MP 702(2nd half day): Cold pulse modulation experiments
SL: cgao
PO: hughes

This half run day is to complete the first part of MP 702. If the run goes smoothly, we will move to the second part of MP702. First of all we will try locked mode shot for HiReX velocity calibration (ref: 1120607004). If locked mode is archived, we will move on to have shots with current and density scans with CaF2 injection from 0.7 - 1.5s, 10Hz.

MP697 - Shoelace Antenna: Survey of boundary plasma response (day 1.5, L-mode)

Half-day - carry-over from 1120619

The primary goal of the MP is to survey the L-mode edge plasma's response to the application of magnetic perturbations from C-Mod's new shoelace antenna system.

Diagnostic setup:
Full set of Mirnov coils
A-port scanning probe with magnetic head
F-port scanning probe
GPI, PCI, differential TCI, reflectometer
Edge Thomson (for EDA H-Mode)
Desired:
Edge Thomson
WASP probe
HIREX, CXRS for rotation

No DNB, ICRF, LH

Overnight ECDC in helium, standard parameters.

Start out: Base plasma from 1120619025
Density target of NL04=0.6

Run Plan

0. Establish plasma

1. Dynamic RGAP scan (1 shot)
Scan RGAP from 0.5-1.5 cm, 0.5-1.5 s. Same field and plasma current from 1120619025
Operate Shoelace antenna at 200 kHz fixed freq., 100 Hz amplitude modulation

2. q-scan, shot-to-shot (3 shots)
*Run Shoelace antenna with staircase frequency ramp, 50,100, and 150 kHz, and modulate amplitude at 100 Hz
*NINJA puff at 0.5 s so that GPI gets data for whole shot - compensate for density target
*RGAP = 0.5 cm
2.a: Reduce field so that q95=3.5
2.b: Modify field so that q95=4.5
2.c: Modify field so that q95=5.5

3. Dynamic q-scan (6 shots)
*RGAP=0.5 cm
3.a - scan q95 from 4 to 5 by ramping up toroidal field, scan Shoelace freq for 10 full triangle cycles in spec. freq. range.
i. Shoelace freq. range = 50-100 kHz
ii. Shoelace freq. range = 100-150 kHz
iii. Shoelace freq. range = 150-200 kHz
3.b - scan q95 from 3 to 4 by ramping up toroidal field, scan Shoelace freq for 10 full triangle cycles in spec. freq. range.
i. Shoelace freq. range = 50-100 kHz
ii. Shoelace freq. range = 100-150 kHz
iii. Shoelace freq. range = 150-200 kHz

4. Time-permiting, do a wide frequency scan from 40-300 kHz on Shoelace antenna, NL04=0.4 (last density scan point), RGAP=0.5 cm, q95=4.8 (Shot 1120619024 should meet these parameters, except for the lower density) (1 shot)

Run summary of 1120620 (2nd half run day, MP702)

We had 15 shots today. (#16 -- #30)

4 fizzles: #22,#23,#26,#29
3 disruptions: #20(0.9s), #21(0.58s), #25(0.47s)
2 locked mode shots: #16, #17
6 full plasma: #18,#19,#24,#27,#28,#30. Of them #18,#24,#27,#28,#30 are good shots for analysis.

(1) Locked mode

#16: good locked mode. But NINJA was on. So it's not perfect for HiReX calibration
#17: very good locked mode. 0.7s - 1.6s

(2) Ip = 0.55MA. Density scan: #18-#20
#18: Good shot. nl04~0.32. SOC. Counter-current rotation. Core Te dropped.
#19: nl04 programmed to 0.24. Density was perturbed too much, and lots of runaways.
reduced the LBO target size by 2.
#20: Disruption at 0.9. Non-thermal electrons for edge GPC channels.
restore LBO target size.

(3)Ip = 1.1MA. Density scan:#21-#30
#21: disruption
#22: post-disruption fizzle
#23: fizzle
#24: Good shot. nl04~0.54. Co-current rotation.LOC. Core Te increased.
#25: disruption
#26: post-disruption fizzle
#27: Good repeat of #24
Bt changed from 5.6T to 5.4T (for CECE)
#28: Good shot. nl04~1.00. SOC. Counter-current rotation. Core Te dropped.
#29: fizzle
increase the LBO target size by ~ 50%
#30: Good shot. nl04~1.20. SOC. Counter-current rotation(but very close to 0). Core Te dropped(channel 1&2 of GPC barely saw Te change).

Overall we had a very good density scan at 1.1MA(2 in LOC, 2 in SOC). We got a SOC shot for 0.55MA, but didn't succeed entering the LOC/low density for 0.55MA. Preliminary analysis shows the evidence of heat pinch for LOC regime. We need to be carefully with the effect of sawtooth on the FFT amplitude analysis.

This half run day was meant to finish the Shoelace survey begun on 1120619, given the problems the machine encountered early in the day. The specific targets of 1120620 were to

1. Complete a dynamic gap scan, so that we might compare data from the wall-mounted, fixed Mirnov coils to the magnetic head on the scanning probe.
2. Perform a q scan to in order to maximize the chance of observing with the GPI diagnostic fluctuations induced by the Shoelace antenna
3. Perform fast frequency scanning during slow, dynamic q scans to look for resonant responses.

Out of 15 attemps, we achieved 10 full-length plasmas, and managed to get through Parts 1 and 2 of the Run Plan, and 2/3 of Part 3.

Off to a clumsy start this morning. The first shot had no PF, which
didn't do a lot for breakdown. We then had a couple of weak fizzles
that seemed mysterious, until we realized the B-top plenum had been
loaded by mistake with He instead of D2. This was remedied by shot 4,
but then we had a recurrence of the common ACK failure that has been
plaguing us of late. Finally shot 5 went (with the EOs bypassing some
additional spurious warning). After that the machine behaved fairly
well, as long as I didn't ask it to do anything absurd.

In the morning I continued with the low-field startup that was
established yesterday. I observed a number of early bounces in this
startup, but most of them ran. I worked on getting the useful flattop
in these shots extended from 0.5 to 1.5s. This involved not only
getting the shape programming settled down by 0.5s, but also
accelerating the current ramp up to try to hasten
cross-over. Eventually we were able to bang out a large portion of
Ted's run plan.

Chi picked up the run starting with shot 16. I forgot to have
engineering reload correct power supply settings for the normal field
startup, but Steve Wolfe caught this, and we corrected it. We began
with some locked mode calibration shots. Interestingly we had NINJA
enabled by mistake on shot 16. This resulted in a density ramp in the
locked mode plasma, with the plasma staying locked thorugh
flattop. There was some good GPI data obtained on this shot. The puff
was turned off for shot 17, which produced a more conventional
locked-mode calibration.

After that we moved on the cold pulse experiments at varying current
and density. The first attempts were at 0.55MA, where some data were
obtained in the SOC regime. Accessing the LOC regime at the target
nl04 of 2.4e19 was very challenging. We mostly made a lot of very very
fast electrons, and had to give up after only a few shots. We moved
on quickly to 1.1MA shots, and after some struggling with
disruption-induced fizzles, we got some data for the SL at both high
and low density.

There were a number of alternator bearing warnings, mainly during the
afternoon. There was also a failure to store the bus Rogowski signals
on shot 26, which I understand to be a very rare event. No reason was
properly determined for this failure.

Scorecard
---------
30 total shots
18 plasmas into rampdown
3 early disruptions
6 fizzles (2 caused by incorrect gas in B-top)
1 Dud (power supply failure)
1 No power test

Next: try again

Jun 20 2012 09:54:23:197AM 1120620004 Theodore Golfinopoulos No-power shot - ack failure

Next: try again

Jun 20 2012 10:24:15:207AM 1120620005 Theodore Golfinopoulos First plasma!

Density is ramping up from the NINJA puffs - Jim Terry will try to tweak a little bit.

Next: try the RGAP scan - ramp RGAP down from 1.5 to 0.5 cm

Jun 20 2012 10:54:15:127AM 1120620006 Theodore Golfinopoulos Shoelace Operation Parameters:
Freq.: 200 kHz, fixed
Amp.: 100 Hz amplitude modulation, amp_wave_w max value=230

Phys. Op. Jerry Hughes gave us a good RGAP scan from around 1.7 cm at 0.62 s to 0.15 cm at 1.5 s. Density is still ramping - varying density didn't have a big effect yesterday, however.

Next: Bring q95 down to 3.5 by changing toroidal field. Staircase Shoelace frequency from 50 -> 100 -> 150 kHz, with amplitude modulation. (Also, drop power level envelope at higher frequencies a bit to avoid tripping). This is part of our q scan for GPI. Jim doesn't think density ramp will affect GPI analysis too much, so we won't try to avoid it.

Jun 20 2012 11:09:26:553AM 1120620007 Theodore Golfinopoulos Shoelace Operation Parameters:
Freq.: Staircase, stepping up from 50 to 100 to 150 kHz
Amp.: 100 Hz AM, in amplitude envelope with amp_wave_w=260 for 50 kHz, 250 for 100 kHz, and 240 for 150 kHz

Result: q95 around 3.7

Next: we will try again, attempting to get RGAP stabilized by 0.6 s. Also, run Shoelace from 0.6 s to 1.5 s, giving equal time of the effective flattop to each of the frequencies.

Jun 20 2012 11:21:13:523AM 1120620008 Theodore Golfinopoulos Shoelace Operation Parameters:
Freq.: Staircase, stepping up from 50 to 100 to 150 kHz
Amp.: 100 Hz AM, in amplitude envelope with amp_wave_w=260 for 50 kHz, 250 for 100 kHz, and 240 for 150 kHz
Antenna is now run between 0.6 to 1.5 s, corresponding to GPI time window. This way, we have equal time on GPI for each frequency.

Result: RGAP stabilizes much earlier - good job, Jerry. q95 around 3.7 - good.
Where in Shot 6, we see the Shoelace on BP_EF_BOT, in Shots 7 and 8, we see no or little signal on this and other of the low-n coils.

Next: March in in scan of q95, varying toroidal field. Target 4.5. Also, try to keep RGAP stable out to 1.5 s.

Jun 20 2012 11:39:27:277AM 1120620009 Theodore Golfinopoulos Shoelace Operation Parameters:
Same as Shot 8
Freq.: Staircase, stepping up from 50 to 100 to 150 kHz
Amp.: 100 Hz AM, in amplitude envelope with amp_wave_w=260 for 50 kHz, 250 for 100 kHz, and 240 for 150 kHz
Antenna is now run between 0.6 to 1.5 s, corresponding to GPI time window. This way, we have equal time on GPI for each frequency.

Result: q95 around 4.5 - on target. We got an injection around 0.87-0.88 s - accept it and move on.
See Shoelace signal on BP_AB_TOP, a little on BP_EF_BOT, and not readily noticeable on BC_BOT or TOP.

Next: Last point in q95 scan - q95=5.5

Jun 20 2012 12:12:44:037PM 1120620010 Theodore Golfinopoulos Shoelace Operation Parameters:
Same as Shot 8
Freq.: Staircase, stepping up from 50 to 100 to 150 kHz
Amp.: 100 Hz AM, in amplitude envelope with amp_wave_w=260 for 50 kHz, 250 for 100 kHz, and 240 for 150 kHz
Antenna is now run between 0.6 to 1.5 s, corresponding to GPI time window. This way, we have equal time on GPI for each frequency.

Result: got a q95 around 5.3-5.4 - good. I think this wraps our shot-to-shot q scan - part 2 of run plan.

Next: dynamic q scan from q95=4 to q95=5. Fast scan of Shoelace frequency, 50 to 100 kHz in ten triangle wave cycles.

Jun 20 2012 12:36:26:840PM 1120620011 Theodore Golfinopoulos Shoelace Operation Parameters:
Freq.: Fast scan, 10 triangle wave cycles from 50 to 100 kHz
Amp.: Fixed (no amplitude modulation), amp_wave_w at 250

Result: we got a nice dynamic q scan from 3.7 to 4.9 - we'll stick with it for our next shot.
See Shoelace signal on BP_EF_BOT at beginning of shot (low q) but not end of shot. It looks like BP_AB_TOP has the opposite situation: you see the Shoelace signal more at the end of the shot (high q) than the beginning.

Doesn't look like we see any poles from the transfer functions.

Next: Same plasma, increase frequency range. Now, 100 to 150 kHz.

Transfer functions:

Next: Try again

Jun 20 2012 12:48:52:803PM 1120620013 Theodore Golfinopoulos Shoelace Operation Parameters:
Freq.: Fast scan, 10 triangle wave cycles from 100 to 150 kHz
Amp.: Fixed (no amplitude modulation), amp_wave_w at 240

Result: Again, BP_EF_BOT shows Shoelace at beginning of shot, and BP_AB_TOP shows it at end. So far, no indication of resonances in transfer functions.

Next: Increase frequency range to 150-200 kHz.

Jun 20 2012 01:06:07:120PM 1120620014 Theodore Golfinopoulos Shoelace Operation Parameters:
Freq.: Fast scan, 10 triangle wave cycles from 150 to 200 kHz
Amp.: Fixed (no amplitude modulation), amp_wave_w at 230

Result: Same pattern on BP_EF_BOT (shows Shoelace early in shot, low q) and BP_AB_TOP (shows Shoelace late, high q)

Next: q scan from 3 to 4, keep Shoelace at fast high frequency scan.

Jun 20 2012 01:04:56:487PM 1120620015 Theodore Golfinopoulos Shoelace Operation Parameters:
Freq.: Fast scan, 10 triangle wave cycles from 150 to 200 kHz
Amp.: Fixed (no amplitude modulation), amp_wave_w at 230

Result: We got a good q scan, q95 from 3.1 to 4.

That's our last shot of the day - ceding to Chi Gao.

result: good shot. nl04 ~ 0.52. LOC. co-current rotation. Core Te increases. Amplitude profile shows evidence of heat pinch.

Next: 1.1MA, nl04 ~ 1.08*1e20. Lower the B field to 5.4T (for CECE)

Today we loaded the shots from 1120216, where the B field was 5.6T, different from 1120106 (B = 5.4T). So CECE doesn't see anything prior this shot.. My fault didn't check it carefully...

Jun 20 2012 05:10:25:463PM 1120620028 Chi Gao plan: 1.1MA, nl04 ~ 1.08*1e20. SOC

result: good shot. nl04 ~ 1.0. SOC. count-current rotation. Core Te decreases.

Next: 1.1MA, nl04 ~ 1.3*1e20. L

Jun 20 2012 05:10:36:980PM 1120620029 Chi Gao plan: 1.1MA, nl04 ~ 1.3*1e20. SOC

result: fizzle

Next: try again

Jun 20 2012 05:45:54:213PM 1120620030 Chi Gao Before this shot, request to increas LBO target size by ~ 50%.

plan: 1.1MA, nl04 ~ 1.3*1e20. SOC

result: Good shot. SOC. Counter-current rotation (but close to 0. More co-current than shot#028.) Core Te drops(channel 1&2 the drop almost disappears)

Last shot of today's run.

Steve Wolfe points out that I forgot to have EO reload the power supply settings
consistent with the normal field startup. Have now asked Gary to load those
settings from 1120614028.

Result: Got the locked mode, but we neglected to disable the NINJA puff.
Interesting that it stays locked, even with density ramp.

Jun 20 2012 01:37:24:843PM 1120620017 Jerry Hughes Shot 17.

Result: Fewer hards, but we get a big disruption at 0.9s, following a
monster density rise. Non-thermals on the ECE would make it difficult to
do a heat pulse analysis under these conditions.

Jun 20 2012 02:51:54:790PM 1120620021 Jerry Hughes Shot 21.

Moving to the high current phase of the experiment:

Set Ip to -1.1e6A in flattop

Session Leader Comments
Jun 20 2012 09:03:48:887AM	1120620001	Theodore Golfinopoulos	Fizzle - no PF - power-supply issue. Next: Try again (establish plasma starting with 1120619025)
Jun 20 2012 09:21:19:140AM	1120620002	Theodore Golfinopoulos	Fizzle - got a flash. Next: try again
Jun 20 2012 09:42:41:810AM	1120620003	Theodore Golfinopoulos	Fizzle with flash. Next: try again
Jun 20 2012 09:54:23:197AM	1120620004	Theodore Golfinopoulos	No-power shot - ack failure Next: try again
Jun 20 2012 10:24:15:207AM	1120620005	Theodore Golfinopoulos	First plasma! Density is ramping up from the NINJA puffs - Jim Terry will try to tweak a little bit. Next: try the RGAP scan - ramp RGAP down from 1.5 to 0.5 cm
Jun 20 2012 10:54:15:127AM	1120620006	Theodore Golfinopoulos	Shoelace Operation Parameters: Freq.: 200 kHz, fixed Amp.: 100 Hz amplitude modulation, amp_wave_w max value=230 Phys. Op. Jerry Hughes gave us a good RGAP scan from around 1.7 cm at 0.62 s to 0.15 cm at 1.5 s. Density is still ramping - varying density didn't have a big effect yesterday, however. Next: Bring q95 down to 3.5 by changing toroidal field. Staircase Shoelace frequency from 50 -> 100 -> 150 kHz, with amplitude modulation. (Also, drop power level envelope at higher frequencies a bit to avoid tripping). This is part of our q scan for GPI. Jim doesn't think density ramp will affect GPI analysis too much, so we won't try to avoid it.
Jun 20 2012 11:09:26:553AM	1120620007	Theodore Golfinopoulos	Shoelace Operation Parameters: Freq.: Staircase, stepping up from 50 to 100 to 150 kHz Amp.: 100 Hz AM, in amplitude envelope with amp_wave_w=260 for 50 kHz, 250 for 100 kHz, and 240 for 150 kHz Result: q95 around 3.7 Next: we will try again, attempting to get RGAP stabilized by 0.6 s. Also, run Shoelace from 0.6 s to 1.5 s, giving equal time of the effective flattop to each of the frequencies.
Jun 20 2012 11:21:13:523AM	1120620008	Theodore Golfinopoulos	Shoelace Operation Parameters: Freq.: Staircase, stepping up from 50 to 100 to 150 kHz Amp.: 100 Hz AM, in amplitude envelope with amp_wave_w=260 for 50 kHz, 250 for 100 kHz, and 240 for 150 kHz Antenna is now run between 0.6 to 1.5 s, corresponding to GPI time window. This way, we have equal time on GPI for each frequency. Result: RGAP stabilizes much earlier - good job, Jerry. q95 around 3.7 - good. Where in Shot 6, we see the Shoelace on BP_EF_BOT, in Shots 7 and 8, we see no or little signal on this and other of the low-n coils. Next: March in in scan of q95, varying toroidal field. Target 4.5. Also, try to keep RGAP stable out to 1.5 s.
Jun 20 2012 11:39:27:277AM	1120620009	Theodore Golfinopoulos	Shoelace Operation Parameters: Same as Shot 8 Freq.: Staircase, stepping up from 50 to 100 to 150 kHz Amp.: 100 Hz AM, in amplitude envelope with amp_wave_w=260 for 50 kHz, 250 for 100 kHz, and 240 for 150 kHz Antenna is now run between 0.6 to 1.5 s, corresponding to GPI time window. This way, we have equal time on GPI for each frequency. Result: q95 around 4.5 - on target. We got an injection around 0.87-0.88 s - accept it and move on. See Shoelace signal on BP_AB_TOP, a little on BP_EF_BOT, and not readily noticeable on BC_BOT or TOP. Next: Last point in q95 scan - q95=5.5
Jun 20 2012 12:12:44:037PM	1120620010	Theodore Golfinopoulos	Shoelace Operation Parameters: Same as Shot 8 Freq.: Staircase, stepping up from 50 to 100 to 150 kHz Amp.: 100 Hz AM, in amplitude envelope with amp_wave_w=260 for 50 kHz, 250 for 100 kHz, and 240 for 150 kHz Antenna is now run between 0.6 to 1.5 s, corresponding to GPI time window. This way, we have equal time on GPI for each frequency. Result: got a q95 around 5.3-5.4 - good. I think this wraps our shot-to-shot q scan - part 2 of run plan. Next: dynamic q scan from q95=4 to q95=5. Fast scan of Shoelace frequency, 50 to 100 kHz in ten triangle wave cycles.
Jun 20 2012 12:36:26:840PM	1120620011	Theodore Golfinopoulos	Shoelace Operation Parameters: Freq.: Fast scan, 10 triangle wave cycles from 50 to 100 kHz Amp.: Fixed (no amplitude modulation), amp_wave_w at 250 Result: we got a nice dynamic q scan from 3.7 to 4.9 - we'll stick with it for our next shot. See Shoelace signal on BP_EF_BOT at beginning of shot (low q) but not end of shot. It looks like BP_AB_TOP has the opposite situation: you see the Shoelace signal more at the end of the shot (high q) than the beginning. Doesn't look like we see any poles from the transfer functions. Next: Same plasma, increase frequency range. Now, 100 to 150 kHz. Transfer functions:
Jun 20 2012 12:13:26:020PM	1120620012	Theodore Golfinopoulos	Fizzle. Next: Try again
Jun 20 2012 12:48:52:803PM	1120620013	Theodore Golfinopoulos	Shoelace Operation Parameters: Freq.: Fast scan, 10 triangle wave cycles from 100 to 150 kHz Amp.: Fixed (no amplitude modulation), amp_wave_w at 240 Result: Again, BP_EF_BOT shows Shoelace at beginning of shot, and BP_AB_TOP shows it at end. So far, no indication of resonances in transfer functions. Next: Increase frequency range to 150-200 kHz.
Jun 20 2012 01:06:07:120PM	1120620014	Theodore Golfinopoulos	Shoelace Operation Parameters: Freq.: Fast scan, 10 triangle wave cycles from 150 to 200 kHz Amp.: Fixed (no amplitude modulation), amp_wave_w at 230 Result: Same pattern on BP_EF_BOT (shows Shoelace early in shot, low q) and BP_AB_TOP (shows Shoelace late, high q) Next: q scan from 3 to 4, keep Shoelace at fast high frequency scan.
Jun 20 2012 01:04:56:487PM	1120620015	Theodore Golfinopoulos	Shoelace Operation Parameters: Freq.: Fast scan, 10 triangle wave cycles from 150 to 200 kHz Amp.: Fixed (no amplitude modulation), amp_wave_w at 230 Result: We got a good q scan, q95 from 3.1 to 4. That's our last shot of the day - ceding to Chi Gao.
Jun 20 2012 01:30:23:647PM	1120620016	Chi Gao	First shot of today's 2nd part run. MP702 plan: Locked mode. loaded from 1120607004 result: Locked at 0.68s. But NINJA was on, density ramped up and temperature went down. HiReX signals went down, not best for calibration. Next: Repeat locked mode. Ted also mentioned he didn't turn off shoelace attenna for tthis shot(should be ok).
Jun 20 2012 01:45:27:500PM	1120620017	Chi Gao	plan: Locked mode. loaded from 1120607004 result: Good locked mode: 0.7s - 1.6s. HiReX doesn't much shift from last Friday. Next: Ip = 0.55MA. nl04 ~ 0.30.
Jun 20 2012 04:09:57:630PM	1120620018	Chi Gao	plan: Ip = 0.55MA. nl04 ~ 0.30. result:Good shot.nl04 ~ 0.36. SOC. GPC both core and edge Te drop(except for channel 3). Diffusive. FRCECE signals are good, except for channel 17-20. Next: Ip = 0.55MA. nl04 ~ 0.24. LOC
Jun 20 2012 05:32:33:123PM	1120620019	Chi Gao	plan: Ip = 0.55MA. nl04 ~ 0.24. LOC result: LBO perturbed density too much. Seems in SOC: counter-current rotation, Te drops in the core and edge. Core Ti increase. Next: Retry. Reduce the LBO target size.
Jun 20 2012 02:53:58:040PM	1120620020	Chi Gao	plan: 1.1MA, nl04 ~ 0.54*1e20 result: Disruption at 0.58s Next: Try again
Jun 20 2012 03:03:58:440PM	1120620020	Chi Gao	plan: Ip = 0.55MA. nl04 ~ 24. LOC result: Disruption at 0.9s. fast electrons(edge channels of GPC) Next: Try LOC at high current. 1.1MA, nl04 ~ 0.54*1e20. restore the LBO target size to normal.
Jun 20 2012 03:05:21:447PM	1120620022	Chi Gao	plan: 1.1MA, nl04 ~ 0.54*1e20 result: fizzle Next: Try again
Jun 20 2012 03:44:12:510PM	1120620024	Chi Gao	plan: 1.1MA, nl04 ~ 0.54*1e20 result: good shot. LOC. 1.1MA. nl04 ~ 0.52. Core Te increases Next: Repeat
Jun 20 2012 03:53:45:523PM	1120620025	Chi Gao	plan: 1.1MA, nl04 ~ 0.54*1e20 result: disruption at 0.47s Next: repeat
Jun 20 2012 03:58:30:150PM	1120620026	Chi Gao	plan: 1.1MA, nl04 ~ 0.54*1e20 result: fizzle Next: repeat
Jun 20 2012 04:39:08:497PM	1120620027	Chi Gao	plan: 1.1MA, nl04 ~ 0.541e20 result: good shot. nl04 ~ 0.52. LOC. co-current rotation. Core Te increases. Amplitude profile shows evidence of heat pinch. Next: 1.1MA, nl04 ~ 1.081e20. Lower the B field to 5.4T (for CECE) Today we loaded the shots from 1120216, where the B field was 5.6T, different from 1120106 (B = 5.4T). So CECE doesn't see anything prior this shot.. My fault didn't check it carefully...
Jun 20 2012 05:10:25:463PM	1120620028	Chi Gao	plan: 1.1MA, nl04 ~ 1.081e20. SOC result: good shot. nl04 ~ 1.0. SOC. count-current rotation. Core Te decreases. Next: 1.1MA, nl04 ~ 1.31e20. L
Jun 20 2012 05:10:36:980PM	1120620029	Chi Gao	plan: 1.1MA, nl04 ~ 1.3*1e20. SOC result: fizzle Next: try again
Jun 20 2012 05:45:54:213PM	1120620030	Chi Gao	Before this shot, request to increas LBO target size by ~ 50%. plan: 1.1MA, nl04 ~ 1.3*1e20. SOC result: Good shot. SOC. Counter-current rotation (but close to 0. More co-current than shot#028.) Core Te drops(channel 1&2 the drop almost disappears) Last shot of today's run.

Physics Operator Comments
Jun 20 2012 09:03:45:363AM	1120620001	Jerry Hughes	Shot 1. Attempt a repeat of 1120619025. Result: Dud. We had no current from OH1, OH2, EF1.
Jun 20 2012 09:27:22:323AM	1120620002	Jerry Hughes	Shot 2. Retry repeat of 1120619025, this time with PF. Result: Fizzle. Pressure is rather low, compared to yesterday.
Jun 20 2012 09:41:27:397AM	1120620003	Jerry Hughes	Shot 3. Changes: In seg1, increase PG4 pre-puff from 23ms to 33ms. Load at 20-Jun-2012 09:31:11.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: Fizzle again. Whoa. We just realized B-top is filled with He instead of D2. That explains a lot. Ron will refill B-top with 6psi D2.
Jun 20 2012 09:53:33:363AM	1120620004	Jerry Hughes	Shot 4. Change: Re-fill B-top with 6psi D2. Load from 1120619025. Load at 20-Jun-2012 09:44:08.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: No power shot. See engops entries for details.
Jun 20 2012 10:25:04:827AM	1120620005	Jerry Hughes	Shot 5: Retry, no PO changes. EO will ignore bad cryo bit in PLC and proceed with shot. Result: Plasma, full length.
Jun 20 2012 10:40:20:507AM	1120620006	Jerry Hughes	Shot 6: Changes: SL requests an RGAP scan. Set RCUR to ramp from 0.660 at 0.6s to 0.668 at 1.5s. Load at 20-Jun-2012 10:23:17.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: Plasma into rampdown. Gap scan looks good.
Jun 20 2012 11:06:11:883AM	1120620007	Jerry Hughes	Shot 7. Changes: Reload 1120620005. (constant Rgap) In Seg 3 Modify IP trace to reach -700000A at 0.5s and holde there until 1.5s. SL wants q95 of 3.5. Currently it is averaging 4.78. Reduce TF from -132700A to -97165A in Seg 3 flattop. Load at 20-Jun-2012 10:50:34.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: Plasma into rampdown. Longer flattop, and earlier cross-over.
Jun 20 2012 11:13:17:863AM	1120620008	Jerry Hughes	Shot 8. Changes: Try to get RGAP mostly settled by 0.5s. Have RCUR come to 0.668 by 0.5s and set CLEARIN to 0.004 by 0.5s. Load at 20-Jun-2012 11:04:18.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: Plasma into rampdown. Crossover occurs around 0.5s, which makes the gap a little unsteady. Also, the gap is increasing after 1.4s.
Jun 20 2012 11:35:10:720AM	1120620009	Jerry Hughes	Shot 9. Changes: Continuing to restore flattop to this shot. In seg 3, extend RCUR @ 0.668 out to 1.5s. Extend CLEARIN trace @0.004 out to 1.5s. Increase the Ip ramp rate between 0.1 and 0.4s to try to speed up cross-over. In addition, SL wants a q95 of 4.5, up from 3.7. Increase TF flattop value from -97165A to -118175A. Load at 20-Jun-2012 11:21:22.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: Plasma into rampdown. A large injection occurs at 0.46s, which the discharge survives. It might be related to crossover, or to a sudden jog in CLEARIN and/or RCUR.
Jun 20 2012 11:45:26:277AM	1120620010	Jerry Hughes	Shot 10: SL wants to change q95 from 4.45 to 5.5. Set flattop TF in seg 3 to -146000A Load at 20-Jun-2012 11:38:28.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: Plasma into rampdown. Reaches flattop Bt by 0.6s. No injections this time.
Jun 20 2012 12:02:05:920PM	1120620011	Jerry Hughes	Shot 11. SL wants a q95 ramp from 4 to 5 obtained using TF. In seg 3, set TF to ramp from -106200A to -132800A from 0.5 to 1.4s. Load at 20-Jun-2012 11:52:10.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: Plasma into rampdown. Bt ramps from 3.9T to 4.8T during Ip flattop.
Jun 20 2012 12:19:13:477PM	1120620012	Jerry Hughes	Shot 12. No PO changes Result: Fizzle. Fields and pressure look very similar to previous shots.
Jun 20 2012 12:33:25:210PM	1120620013	Jerry Hughes	Shot 13 Alternator reports a city water pressure warning. Temporary spin down and reset. Should not be a long delay. Change: In seg 1 reduce PG4 pre-puff from 23ms to 21ms. Load at 20-Jun-2012 12:21:56.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: Full length plasma.
Jun 20 2012 12:54:02:590PM	1120620014	Jerry Hughes	Shot 14. No PO changes. Result: Plasma into rampdown.
Jun 20 2012 01:28:18:980PM	1120620015	Jerry Hughes	Shot 15. Changes: SL wants a q95 ramp from 3 to 4. In seg 3, change TF @0.5s from -106200A to -79650A Change TF @1.5s from -132800A to -106200A Load at 20-Jun-2012 12:52:54.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: Plasma into rampdown. SL is pleased with his q ramp. End of AM run.
Jun 20 2012 01:26:45:400PM	1120620016	Jerry Hughes	Shot 16. Beginning Chi Gao's run. Load from 1120216023. Import seg4 of 1120607004 into seg3. (a locked mode calibration) Import seg1 of 1120614028 into seg1. (a recent 5.4T non-cryopump startup) In seg1, set PG4 pre-puff to 21ms. Next, turn OFF seg 2 and turn ON Seg 3 Load at 20-Jun-2012 13:08:58.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Steve Wolfe points out that I forgot to have EO reload the power supply settings consistent with the normal field startup. Have now asked Gary to load those settings from 1120614028. Result: Got the locked mode, but we neglected to disable the NINJA puff. Interesting that it stays locked, even with density ramp.
Jun 20 2012 01:37:24:843PM	1120620017	Jerry Hughes	Shot 17. No PO changes. Repeat locked mode shot without NINJA. Result: Plasma into rampdown. Looks pretty well locked.
Jun 20 2012 01:58:19:143PM	1120620018	Jerry Hughes	Shot 18. Move to physics shots. Increase B-side lower fill from 1 to 1.5psi Turn OFF seg 3 and turn ON seg 2. In seg 2, increase PG1 puff to 175ms, per SL plan. nl04 is set to 3e19. Keep here and see what the outcome is. Load at 20-Jun-2012 13:43:38.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: Plasma into rampdown. The nl04 is fairly close to SL's 2(b) request.
Jun 20 2012 02:18:21:703PM	1120620019	Jerry Hughes	Shot 19. Changes: Drop nl04 program in seg 2 to 2.4e19 In seg 1, reduce PG3 maintenance puff from 60 to 30V. Load at 20-Jun-2012 14:02:21.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: Lots of hards, but we got down to the requested target density.
Jun 20 2012 02:45:15:767PM	1120620020	Jerry Hughes	Shot 20 Changes: Increase PG3 back-porch at t=0 from 30 to 40V. Load at 20-Jun-2012 14:20:56.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: Fewer hards, but we get a big disruption at 0.9s, following a monster density rise. Non-thermals on the ECE would make it difficult to do a heat pulse analysis under these conditions.
Jun 20 2012 02:51:54:790PM	1120620021	Jerry Hughes	Shot 21. Moving to the high current phase of the experiment: Set Ip to -1.1e6A in flattop Set nl04 to 5.4e19 in flattop Also in seg 1, reduce prefill to 19ms to account for the disruption on 19. Load at 20-Jun-2012 14:41:43.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: Disruption at 0.58s, (following a monster sawtooth?)
Jun 20 2012 02:59:17:313PM	1120620022	Jerry Hughes	Shot 22. Changes: Raise PG3 t0 backporch form 40 to 60V. Increase p-gain on nl04 at starting at 0.4s. Load at 20-Jun-2012 14:56:05.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: post-disruption fizzle
Jun 20 2012 03:17:15:603PM	1120620023	Jerry Hughes	Shot 23. Retry. No PO changes. Result: Fizzle
Jun 20 2012 03:39:10:093PM	1120620024	Jerry Hughes	Shot 24. In seg 1, reduce PG4 pre-puff to 18ms. Load at 20-Jun-2012 15:18:52.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: Full length plasma, just in time for the tour group! SLs like the shot so much they want to repeat it. Probably the best startup I've had all day too.
Jun 20 2012 03:49:25:013PM	1120620025	Jerry Hughes	Shot 25 No PO changes. result: Locked mode at 0.42s, following an unwanted drop in the density.
Jun 20 2012 03:57:43:273PM	1120620026	Jerry Hughes	Shot 26 Changes: Apply a longer PG3 back-porch in seg 1. (out to 0.039s) Up the prop gain on the nl04 controller starting at 0.2s. Load at 20-Jun-2012 15:52:21.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: Post-disruption fizzle
Jun 20 2012 04:28:40:823PM	1120620027	Jerry Hughes	Shot 27 No PO changes Result: Runs through. Looks like a good repeat of 24.
Jun 20 2012 04:44:53:137PM	1120620028	Jerry Hughes	Shot 28 Changes: In Seg 2, change TF from -153000A to -148865A. In flattop, set nl04 to 1.08e20. Update Seg 2 title to "2012 1.11 MA, LSN, 5.4T" Load at 20-Jun-2012 16:37:43.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: Plasma into rampdown. Decent startup. Shot did what we wanted.
Jun 20 2012 04:56:12:137PM	1120620029	Jerry Hughes	Shot 29. Change: In seg 2 set nl04 to 1.3e20 Load at 20-Jun-2012 16:52:02.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Result: Fizzle.
Jun 20 2012 05:19:03:623PM	1120620030	Jerry Hughes	Shot 30. No PO changes. Result: Shot went through. EOR
