Run Plan for 1080110

MP#489 "Damping rate of TAEs near stability threshold with ICRF fast ions"

Goal
****
Observe the stability of moderate n (~6-14) TAEs as the ICRF power is increased from shot to shot. Confirm effect of energetic tail profile on TAE stability.

Run Preparation
***************
* Prepare argon for HIREX
* Setup GPC2 gratings for -5.9 T
* Set CNPA aperture to 208, bias voltage to 45V
* Operate DNB during interval:
* Operate Thomson
* Observe CXRS for core boron density measurements
* Operate PCI if available
* Enable the dpcs_ftae2 procedure in DPCS
* Turn on Active MHD and set qAE to 1.5, AE_order to 2

Plasma Conditions
*****************
* load equilibrium from 1080109025
* this shot is L-mode, upper single null
* change outer gap to 8mm
* change to Bt=-5.9T
* change to nl04=7e19
* change to Ip=-600MA
* leave argon puffing for HYREX

Shot Sequence
*************
Increment RF power by 0.5MW, starting at 0MW. At each power, excite the upper Active MHD antenna first at the q=1.5 frequency, then in a second shot at the q=1 frequency. If unstable TAEs are observed at higher RF powers, repeat shot to attempt to reproduce the mode. Continue incrementing by 0.5MW to highest RF power that can be achieved, even if H-mode is encountered.

If RF power scan is completed, return to moderate power (eg 2MW). Execute a series of shots at -5.9T, -5.7T, -5.4T and -5.1T, to look for the radial distribution of the ion tail with the CNPA as a benchmark for modeling codes.

This was a very successful scan to high RF powers to hunt for the TAE stability threshold. L mode was maintained in these USN configurations above the usual H mode threshold by injecting large amounts of argon to increase radiated power. Unstable TAEs were observed at RF powers above 3.5MW. The ICRF functioned brilliantly and powers up to 5.5MW for 0.5s were achieved.

Other diagnostics also contributed to a successful run. All three channels of the cnpa were operational, giving a spatial and energy distribution of the energetic particles at each RF power level. The neutral beam worked most of the time which will improve the number of particle counts and the resolution. The PCI was up for the first day this campaign and observed both unstable modes and the Active MHD perturbation in some cases.

Run summary for Thursday 10 Jan 2008

MP#489 Damping of TAEs at the threshold of stability in the presence
of ICRF-heated fast ions

Session leader: J. Sears
Physics operator: R. Granetz

Plasma operation was pretty reliable today. We ran upper null, low current
(0.6 MA) discharges at 5.9 tesla today, and got the ICRF power up to 5.5 MW
for 0.4 s, and 4.5+ MW for 1 second. Shot 22 had a total of 4.4 MJ of ICRF
energy injected, which may be a new record for C-Mod. At these high
powers, even the upper null plasmas were going into H-mode, so we
effectively avoided this during the latter part of the run by puffing very
large amounts of argon, in conjunction with running the cryopump. This was
very effective and kept the plasma from disrupting for the most part. For
most of the day we had only a 5 mm outer gap, to aid the Mirnov pickup
signals. However, at the 5.5 MW level this resulted in overheating of
something (G/H limiter?) on shots 26 and 27. We then increased the outer
gap to 10 mm for the remainder of the run, and decreased the RF power.

There were two shots which failed because the EF3 breaker pulled out
before the shot, and we also had one shot that blew a TF fuse
(1080110011).

See the session leader's run summary for results on the TAE measurements.

Physics Operator Comments

Jan 10 2008 09:06:47:803AM 1080110001 Robert Granetz Shot 01 -- Fizzle. Pre-fill pressure was 0.12 mTorr. Pre-fill pulse was 45 ms! I grabbed
this startup from yesterday...don't know why the pre-fill pulse was so long.
DNB is firing into the plasma, but it doesn't need this much extra pre-fill.

Next shot: set pre-fill pulse to 28 ms.

Jan 10 2008 09:26:23:250AM 1080110001 Robert Granetz Steve Wukitch reminded me that yesterday the cryopump was being used, which explains
the long pre-fill pulse.

Jan 10 2008 09:23:36:420AM 1080110002 Robert Granetz Shot 02 -- Plasma. Good shot. 0.6 MA, 5.9 T, upper null, nl_04=6.6e19 m-2. Outer gap = 8-9 mm.
RF faulted a lot.

Next shot: turn on argon; decrease outer gap to 4 mm (increase RCUR by 2 mm); retry for better RF.

Jan 10 2008 09:43:18:740AM 1080110003 Robert Granetz Shot 03 -- Plasma. Good shot. Outer gap varies from 6 mm down to 4 mm during the flattop.
Got good 0.5 MW pulse from D-port. Video cameras don't show any overheating of
D or J antenna edges.

Next shot: Tweak RCUR programming to get a more constant 4 mm outer gap.

Jan 10 2008 09:54:11:253AM 1080110004 Robert Granetz Shot 04 -- Plasma. Good shot. Prf=1 MW. (We're stepping up the ICRF power by 0.5 MW
on a shot-to-shot basis for this MP.) Outer gap is now very constant, but for
some reason it's shrunk to just 2 mm.

Next shot: increase outer gap to 4 mm (move RCUR in by 1 mm). Try for 1.5 MW ICRF power.

Jan 10 2008 10:02:55:907AM 1080110005 Robert Granetz Shot 05 -- Plasma. Good shot. Prf=1.5 MW (as requested). Outer gap jumped to 6 mm, not 4.

Next shot: Another RCUR tweak. Prf=2 MW.

Jan 10 2008 10:24:35:710AM 1080110006 Robert Granetz Shot 06 -- Plasma. Good shot. Prf=2 MW (as requested). Outer gap = 4-5 mm except
early in the flattop. I don't think I can control it better than this.

Next shot: no DPCS changes. Prf=2.5 MW

Jan 10 2008 10:36:30:097AM 1080110007 Robert Granetz Shot 07 -- Plasma. Good shot. Prf=2.44 MW, as requested. Still no overheating
seen on the D and J video views.

Next shot: no DPCS changes. Prf will stay at 2.5 MW.

Jan 10 2008 10:52:40:653AM 1080110008 Robert Granetz Shot 08 -- Plasma. Good shot. Prf=2.5 MW. Outer gap = 4 mm.
H/(H+D) is saying 2-3%.

Next shot: no DPCS changes. Prf staying at 2.5 MW.

Jan 10 2008 11:00:09:650AM 1080110009 Robert Granetz Shot 09 -- Fizzle.

Next shot: reduce pre-fill by 3 ms.

Jan 10 2008 11:16:22:567AM 1080110010 Robert Granetz Shot 10 -- Fizzle. This one also should have gone.

Next shot: add -0.2 mT to Br0; add 1 ms to pre-fill.

Jan 10 2008 11:35:26:340AM 1080110011 Robert Granetz Shot 11 -- Plasma. Good shot. Good startup. Prf=2.5 MW.

There was a ""glitch"" in TF converter #1 which will require a
power room access.

Next shot: no DPCS changes.

Jan 10 2008 12:00:35:753PM 1080110011 Robert Granetz There was a long break between shots 11 and 12 to replace a fuse in the TF cabinet
and high-pot it.

Jan 10 2008 12:16:05:463PM 1080110013 Robert Granetz Shot 12 -- Plasma. Good shot. D-port failed though. Lithium pellet was injected at t=1.45 s.

Next shot: no DPCS changes.

Jan 10 2008 12:23:45:273PM 1080110013 Robert Granetz Shot 13 -- Plasma. Good shot. Prf=2 MW, as requested.

Next shot: no DPCS changes

Jan 10 2008 12:38:02:253PM 1080110014 Robert Granetz Shot 14 -- Plasma. Good shot. Prf=1.4 MW, as requested. Li pellet at 1.45 s.

Next shot: no DPCS changes

Jan 10 2008 12:54:41:823PM 1080110015 Robert Granetz Shot 15 -- Plasma. Good shot. Prf=0.5 MW. The DANT camera caught the lithium
pellet streaking into the plasma (frame 43).

Next shot: no DPCS changes

Jan 10 2008 01:14:45:880PM 1080110017 Robert Granetz Shot 17 -- Fizzle. Everything looks fine.

Next shot: reduce Br0 by another 0.2 mT (to 0.0000 T)

Jan 10 2008 02:30:00:913PM 1080110017 Robert Granetz Shot 16 -- Plasma. Good shot. Prf=3 MW, as requested.

Next shot: no DPCS changes

Jan 10 2008 01:38:15:777PM 1080110018 Robert Granetz Shot 18 -- Plasma. Disrupted at t=0.93 s. Prf=3.5 MW, which caused this upper null plasma to
go into H-mode. It looks like an injection killed the plasma.

Next shot: no DPCS changes

Jan 10 2008 02:08:47:843PM 1080110019 Robert Granetz Shot 19 -- Plasma. Good shot. 3.5 MW, long pulse. H/(H+D)=4-5%.

Cell access granted for various people

Next shot: increase argon puff to 0.5 s (t=0.3 to 0.8 s) and turn on cryopump.
This is to try and keep us out of H-mode.

Jan 10 2008 02:21:22:540PM 1080110020 Robert Granetz Shot 20 -- Dud. I forgot to increase the pre-fill to compensate for turning on the cryopump.

Next shot: increase pre-fill by 15 ms.

Jan 10 2008 02:43:37:627PM 1080110021 Robert Granetz Shot 21 -- Plasma. Good shot. Prf=4+ MW, long pulse. The argon kept us in L-mode, as
desired. The cryopump kept the argon from killing the shot. Trophy shot.
H/(H+D) = 5%

Next shot: increase argon puff duration to 1.0 s (t=0.3 to 1.3 s). Cryopump on again.
Prf=4+ MW again. Also add 2 more ms to pre-fill.

Jan 10 2008 02:53:47:950PM 1080110022 Robert Granetz Shot 22 -- Plasma. Good shot. Prf=4.5+ MW for 1.0 s. Total RF energy = 4.4 MJ (a record?).
Stayed in L-mode due to massive argon puff; Cryopump kept the argon from disrupting
the plasma.

Next shot: repeat same shot. Cryopump on, Prf=4.5+ MW, argon puff = 1.0 s.

Jan 10 2008 02:59:39:387PM 1080110023 Robert Granetz Shot 23 -- Dud. EF3 failed. Breaker pulled just before the shot.

Next shot: try again

Jan 10 2008 03:21:20:877PM 1080110024 Robert Granetz Shot 24 -- Plasma. Good shot. D-port antenna faulted out. Prf=2.5 MW.

Next shot: try again with all antennas

Jan 10 2008 03:36:13:170PM 1080110025 Robert Granetz Shot 25 -- Plasma. Good shot. Prf=4.1 MW for 1+ s. H/(H+D)=6%

Next shot: more RF power (5+ MW)

Jan 10 2008 03:45:04:290PM 1080110026 Robert Granetz Shot 26 -- Plasma. Disrupted at t=0.83 s. Prf=5.5+ MW.

Next shot: increase the argon plenum pressure to 2 psi (from 1 psi). Keep the pulse
length at 1.0 s.

Jan 10 2008 04:01:05:393PM 1080110027 Robert Granetz Power room access was needed after shot 27 to look again at TF converter cabinet #1.
We may have blown another fuse.

Jan 10 2008 04:09:42:000PM 1080110027 Robert Granetz Shot 27 -- Plasma. Disrupted at t=0.91 s. Prf=5.5 MW for 0.4 s !!! Something's getting
hot on the outer wall near G/H; probably the G/H limiter. Outer gap is 5 mm.

Next shot: increase outer gap to 1.0 cm (decrease RCUR by 2.5 mm). Also move
the outboard strikepoint in by 5 mm to get it inboard of the slots in
ceiling. (Move RXU in by 5 mm.)

Jan 10 2008 04:16:59:467PM 1080110028 Robert Granetz Shot 28 -- Fizzle. Fill pressure was somewhat higher, but not by a big factor, so I
think the cryopump still has helium in it.

Next shot: decrease pre-fill by 4 ms

Jan 10 2008 04:32:19:850PM 1080110029 Robert Granetz Shot 29 -- Plasma. Disrupted at t=1.42 s. Prf=4.5 MW for 0.9 s.

Next shot: turn off cryopump and decrease pre-fill to 26 ms to compensate. Also
reduce argon plenum pressure back to 1 psi and reduce the argon puff
back to 100 ms.

Jan 10 2008 04:40:53:957PM 1080110030 Robert Granetz Shot 30 -- No-power shot because the EF3 breaker pulled out in CHECK state.

Next shot: try again. The RF power will be 3 MW.

Jan 10 2008 04:57:46:433PM 1080110031 Robert Granetz Shot 31 -- Plasma. Good shot. Prf=3 MW, as requested.

Next shot: Set Btor = 5.1 tesla.

Jan 10 2008 05:07:55:307PM 1080110032 Robert Granetz Shot 32 -- Plasma. Good shot. Prf=3 MW, as requested. This shot had lots of short
H-modes because the massive argon puffing is no longer being done (just the
usual 100 ms puff). Btor=5.1 tesla.

End of run.

Physics Operator Comments
Jan 10 2008 09:06:47:803AM	1080110001	Robert Granetz	Shot 01 -- Fizzle. Pre-fill pressure was 0.12 mTorr. Pre-fill pulse was 45 ms! I grabbed this startup from yesterday...don't know why the pre-fill pulse was so long. DNB is firing into the plasma, but it doesn't need this much extra pre-fill. Next shot: set pre-fill pulse to 28 ms.
Jan 10 2008 09:26:23:250AM	1080110001	Robert Granetz	Steve Wukitch reminded me that yesterday the cryopump was being used, which explains the long pre-fill pulse.
Jan 10 2008 09:23:36:420AM	1080110002	Robert Granetz	Shot 02 -- Plasma. Good shot. 0.6 MA, 5.9 T, upper null, nl_04=6.6e19 m-2. Outer gap = 8-9 mm. RF faulted a lot. Next shot: turn on argon; decrease outer gap to 4 mm (increase RCUR by 2 mm); retry for better RF.
Jan 10 2008 09:43:18:740AM	1080110003	Robert Granetz	Shot 03 -- Plasma. Good shot. Outer gap varies from 6 mm down to 4 mm during the flattop. Got good 0.5 MW pulse from D-port. Video cameras don't show any overheating of D or J antenna edges. Next shot: Tweak RCUR programming to get a more constant 4 mm outer gap.
Jan 10 2008 09:54:11:253AM	1080110004	Robert Granetz	Shot 04 -- Plasma. Good shot. Prf=1 MW. (We're stepping up the ICRF power by 0.5 MW on a shot-to-shot basis for this MP.) Outer gap is now very constant, but for some reason it's shrunk to just 2 mm. Next shot: increase outer gap to 4 mm (move RCUR in by 1 mm). Try for 1.5 MW ICRF power.
Jan 10 2008 10:02:55:907AM	1080110005	Robert Granetz	Shot 05 -- Plasma. Good shot. Prf=1.5 MW (as requested). Outer gap jumped to 6 mm, not 4. Next shot: Another RCUR tweak. Prf=2 MW.
Jan 10 2008 10:24:35:710AM	1080110006	Robert Granetz	Shot 06 -- Plasma. Good shot. Prf=2 MW (as requested). Outer gap = 4-5 mm except early in the flattop. I don't think I can control it better than this. Next shot: no DPCS changes. Prf=2.5 MW
Jan 10 2008 10:36:30:097AM	1080110007	Robert Granetz	Shot 07 -- Plasma. Good shot. Prf=2.44 MW, as requested. Still no overheating seen on the D and J video views. Next shot: no DPCS changes. Prf will stay at 2.5 MW.
Jan 10 2008 10:52:40:653AM	1080110008	Robert Granetz	Shot 08 -- Plasma. Good shot. Prf=2.5 MW. Outer gap = 4 mm. H/(H+D) is saying 2-3%. Next shot: no DPCS changes. Prf staying at 2.5 MW.
Jan 10 2008 11:00:09:650AM	1080110009	Robert Granetz	Shot 09 -- Fizzle. Next shot: reduce pre-fill by 3 ms.
Jan 10 2008 11:16:22:567AM	1080110010	Robert Granetz	Shot 10 -- Fizzle. This one also should have gone. Next shot: add -0.2 mT to Br0; add 1 ms to pre-fill.
Jan 10 2008 11:35:26:340AM	1080110011	Robert Granetz	Shot 11 -- Plasma. Good shot. Good startup. Prf=2.5 MW. There was a ""glitch"" in TF converter #1 which will require a power room access. Next shot: no DPCS changes.
Jan 10 2008 12:00:35:753PM	1080110011	Robert Granetz	There was a long break between shots 11 and 12 to replace a fuse in the TF cabinet and high-pot it.
Jan 10 2008 12:16:05:463PM	1080110013	Robert Granetz	Shot 12 -- Plasma. Good shot. D-port failed though. Lithium pellet was injected at t=1.45 s. Next shot: no DPCS changes.
Jan 10 2008 12:23:45:273PM	1080110013	Robert Granetz	Shot 13 -- Plasma. Good shot. Prf=2 MW, as requested. Next shot: no DPCS changes
Jan 10 2008 12:38:02:253PM	1080110014	Robert Granetz	Shot 14 -- Plasma. Good shot. Prf=1.4 MW, as requested. Li pellet at 1.45 s. Next shot: no DPCS changes
Jan 10 2008 12:54:41:823PM	1080110015	Robert Granetz	Shot 15 -- Plasma. Good shot. Prf=0.5 MW. The DANT camera caught the lithium pellet streaking into the plasma (frame 43). Next shot: no DPCS changes
Jan 10 2008 01:14:45:880PM	1080110017	Robert Granetz	Shot 17 -- Fizzle. Everything looks fine. Next shot: reduce Br0 by another 0.2 mT (to 0.0000 T)
Jan 10 2008 02:30:00:913PM	1080110017	Robert Granetz	Shot 16 -- Plasma. Good shot. Prf=3 MW, as requested. Next shot: no DPCS changes
Jan 10 2008 01:38:15:777PM	1080110018	Robert Granetz	Shot 18 -- Plasma. Disrupted at t=0.93 s. Prf=3.5 MW, which caused this upper null plasma to go into H-mode. It looks like an injection killed the plasma. Next shot: no DPCS changes
Jan 10 2008 02:08:47:843PM	1080110019	Robert Granetz	Shot 19 -- Plasma. Good shot. 3.5 MW, long pulse. H/(H+D)=4-5%. Cell access granted for various people Next shot: increase argon puff to 0.5 s (t=0.3 to 0.8 s) and turn on cryopump. This is to try and keep us out of H-mode.
Jan 10 2008 02:21:22:540PM	1080110020	Robert Granetz	Shot 20 -- Dud. I forgot to increase the pre-fill to compensate for turning on the cryopump. Next shot: increase pre-fill by 15 ms.
Jan 10 2008 02:43:37:627PM	1080110021	Robert Granetz	Shot 21 -- Plasma. Good shot. Prf=4+ MW, long pulse. The argon kept us in L-mode, as desired. The cryopump kept the argon from killing the shot. Trophy shot. H/(H+D) = 5% Next shot: increase argon puff duration to 1.0 s (t=0.3 to 1.3 s). Cryopump on again. Prf=4+ MW again. Also add 2 more ms to pre-fill.
Jan 10 2008 02:53:47:950PM	1080110022	Robert Granetz	Shot 22 -- Plasma. Good shot. Prf=4.5+ MW for 1.0 s. Total RF energy = 4.4 MJ (a record?). Stayed in L-mode due to massive argon puff; Cryopump kept the argon from disrupting the plasma. Next shot: repeat same shot. Cryopump on, Prf=4.5+ MW, argon puff = 1.0 s.
Jan 10 2008 02:59:39:387PM	1080110023	Robert Granetz	Shot 23 -- Dud. EF3 failed. Breaker pulled just before the shot. Next shot: try again
Jan 10 2008 03:21:20:877PM	1080110024	Robert Granetz	Shot 24 -- Plasma. Good shot. D-port antenna faulted out. Prf=2.5 MW. Next shot: try again with all antennas
Jan 10 2008 03:36:13:170PM	1080110025	Robert Granetz	Shot 25 -- Plasma. Good shot. Prf=4.1 MW for 1+ s. H/(H+D)=6% Next shot: more RF power (5+ MW)
Jan 10 2008 03:45:04:290PM	1080110026	Robert Granetz	Shot 26 -- Plasma. Disrupted at t=0.83 s. Prf=5.5+ MW. Next shot: increase the argon plenum pressure to 2 psi (from 1 psi). Keep the pulse length at 1.0 s.
Jan 10 2008 04:01:05:393PM	1080110027	Robert Granetz	Power room access was needed after shot 27 to look again at TF converter cabinet #1. We may have blown another fuse.
Jan 10 2008 04:09:42:000PM	1080110027	Robert Granetz	Shot 27 -- Plasma. Disrupted at t=0.91 s. Prf=5.5 MW for 0.4 s !!! Something's getting hot on the outer wall near G/H; probably the G/H limiter. Outer gap is 5 mm. Next shot: increase outer gap to 1.0 cm (decrease RCUR by 2.5 mm). Also move the outboard strikepoint in by 5 mm to get it inboard of the slots in ceiling. (Move RXU in by 5 mm.)
Jan 10 2008 04:16:59:467PM	1080110028	Robert Granetz	Shot 28 -- Fizzle. Fill pressure was somewhat higher, but not by a big factor, so I think the cryopump still has helium in it. Next shot: decrease pre-fill by 4 ms
Jan 10 2008 04:32:19:850PM	1080110029	Robert Granetz	Shot 29 -- Plasma. Disrupted at t=1.42 s. Prf=4.5 MW for 0.9 s. Next shot: turn off cryopump and decrease pre-fill to 26 ms to compensate. Also reduce argon plenum pressure back to 1 psi and reduce the argon puff back to 100 ms.
Jan 10 2008 04:40:53:957PM	1080110030	Robert Granetz	Shot 30 -- No-power shot because the EF3 breaker pulled out in CHECK state. Next shot: try again. The RF power will be 3 MW.
Jan 10 2008 04:57:46:433PM	1080110031	Robert Granetz	Shot 31 -- Plasma. Good shot. Prf=3 MW, as requested. Next shot: Set Btor = 5.1 tesla.
Jan 10 2008 05:07:55:307PM	1080110032	Robert Granetz	Shot 32 -- Plasma. Good shot. Prf=3 MW, as requested. This shot had lots of short H-modes because the massive argon puffing is no longer being done (just the usual 100 ms puff). Btor=5.1 tesla. End of run.
