MP#356 Mode conversion current drive in D[3He] at 50 MHz

The primary goal of this run is to measure net current drive from mode converted waves using loop voltage differences between co/counter phasing. This involves establishing an acceptable target discharge maximizing the efficiency (~ Te/(ne Zeff) according to parametrizations).

Special gas: He3 15 PSI, B-side Upper
Diagnostics: standard set, with ECE (~5-5.5T setup) and PCI (50 MHz, no localization).

Run plan:
1) Start with 1050629014 (USN, 5.4T, 1 MA, nl04 ~ 0.8), but with Ip = 600 kA, nl04 ~ 0.6, B_T = 5.5 T
Set helium 3 puff at .3 sec, 250 ms (target 3He concentration is ~ 20%)
ICRF waveform : 0.6-1.4 sec, Ramp up ICRF power,
* 0.6 - 1.0 sec: J port alone, 2.0 --> 3.0 MW, heating phase, with notches (if necessary) for break in slope
* 1.0 - 1.4 sec: 3 MW J-port and ramp up E port to 1.5 MW).
Thus determine maximum power below H-mode threshold and compatible with antenna operation.
Decrease the density further to minimize (ne x Zeff) and possibly increase H-mode threshold.
Readjust puff to have 3He concentration around 20%, based on break-in-slope. (5-10 shots)

2) Using the best target from 1), square ICRF waveform from J and E, from 0.6 sec to 1.4 sec.
Do a field scan to vary the deposition location around the magnetic axis, repeating discharges with +90, -90 and
heating phasing. Look at loop voltage changes between co/counter to determine possible current drive. (15 shots)
Target mode conversion layer locations: r/a = 0., 0.05, 0.10, 0.15, 0.2 on the HFS.
Corresponding values of the B_T: 5.73T, 5.63T, 5.53T, 5.43T, 5.38T (will be readjusted from concentration estimates
in part 1).

3) If time allows, lower toroidal field and do a field ramp across the HFS q=1 surface and investigate changes in the
sawtooth period, repeating discharges with +90, -90 and heating phasing. Start with B_T from ~ 4.9T to 5.4T, then do a
smaller (and slower) ramp around values of B_T where changes in the sawtooth period are observed. (6-9 shots)

We obtained very good results on the sawtooth control part of the experiment.
By sweeping the mode conversion layer through the inversion radius with a toroidal field ramp, we were able to increase the sawtooth period to 10 ms in co-CD phasing (shot 27) and decrease it to 4 ms in counter-CD phasing (shot 26). This is consistent with local changes in the shear at the q = 1 surface from currents driven by the mode converted waves.

In the early part of the run, we spent some time developing an acceptable target for current drive measurements using loop voltage analysis. We could not get the density lower than nl04 = 0.8e20 m^-2 in upper single null. The shape was changed to inner wall limited, and the 3He puff was moved earlier (0.2 sec) and reduced in duration (100 ms time). In those conditions, better plasma targets were obtained (e.g. shot 19) with nl04 ~ 0.6 m^-2 (ne0 ~ 1.5e20), Te0 ~ 4 keV and a helium 3 concentration around 20%, however with Zeff reaching 4. An initial loop voltage comparison between co- and counter CD phasing was conducted
in shots 19 and 20, but no clear evidence of current drive could be observed.
Overall, we made progress but the target conditions are not yet optimal, leading to lower current drive efficiencies than desired for part 2.

We switched to part 3 after shot 21 and looked at changes in the sawtooth period. Although we had several fizzles and disruptions, significant changes in the sawtooth period could be obtained, as mentionned above.

The RF ran very well today with E to 1.5 MW and J-port to 3 MW in heating, co and counter CD phasings. The plasma stayed in L-mode even with 4.5 MW RF power. Good break-in-slope and PCI data was collected throughout the day, and will be useful for analysis.

This was a difficult run because very low densities were required at very high RF power. We started
with upper null plasmas to avoid H-mode, but after shot 1050729013, we went to inner wall limited because it
appeared that the upper divertor plates could not handle the heat load of more than 4 MW RF power for
multiple shots. The inner wall discharges did seem to perform better initially and some valuable results
were obtained. Density control was difficult as the 3He puff increased the density and there were apparently
wall sources as well. After a number of inner wall shots, the density did reach the desired 6 x 10^19 m^-2.
However, even the inner wall discharges were plagued with runaways and with disruptions due to impurity
injections. There were also a number of fizzles toward the end of the run. Perhaps between shot ECDC would
have been helpful to improve the discharge quality, but it was not attempted. John Rice reported very high
molybdenum levels throughout the day. Still, we had 37 discharges with 19 full length plasmas and one or two
more that last throughout most of the RF pulse. So, there should be some valuable physics data obtained. See
the session leader summary for details.

Next. Request nl04 to 0.4

Jul 29 2005 10:09:33:593AM1050729005Alexandre ParisotNo power shot.
RF is doing OK and we're not getting H-mode, so we can start moving to the next part while we're trying to get lower densities.
J-port and E-port flat waveforms 0.6 to 1.4 sec, keep notches in J-port.
Mode conversion appears on the PCI.

Next. Repeat

Jul 29 2005 10:24:53:703AM1050729006Alexandre ParisotPlasma. Still no change in nl04 during the flat-top.

Next. Move 3He puff to 0.25 sec.

Jul 29 2005 10:52:16:313AM1050729008Alexandre ParisotPlasma. Density in flatop did not go down. Less D-puff.
J-port in heating phase.

Next. Move 3He puff to 200ms.

Jul 29 2005 11:04:35:563AM1050729009Alexandre ParisotPlasma. Slight decrease in density. No D-puff after 0.1 sec.
The rise in density seems to come from the 3He puff, since we're already low in 3He concentration, we don't want to lower it.

J-port in counter-CD phasing.

Next. Go Inner Wall limited.
Jul 29 2005 12:12:34:330PM1050729014Alexandre ParisotRan inner wall limited.
nl04 ~ 1.0, E-port ran but not J-port.
The plasma touches the outer limiter.
We might be too high on the 3He concentration (maybe because we puffed earlier).

Next. Increase the gap and lower 3He puff time to 150 ms.
Jul 29 2005 12:34:32:000PM1050729015Alexandre ParisotRan inner wall limited.

Jul 29 2005 02:51:49:877PM1050729016Alexandre ParisotRan inner wall limited. No change in density.
At this point, it appears we are not succesfull in establishing a proper target for part 2). The density is way too high, and we cannot get it any lower.
Take another shot with lower 3He puff time, then move to part 3 (sawtooth control), which requires a smaller current drive efficiency.

Next. Lower 3He puff time to 100 ms [0.2-0.3 s].
Jul 29 2005 12:54:53:550PM1050729017Alexandre ParisotRan inner wall limited.

nl04 ~ 0.6-0.7. No FRC-ECE.
Mode conversion layer crosses inversion radius at the end of the RF pulse.
Zeff goes to 4. From GPC @ 1.4s, 3He concentration is between 15 and 20%.

next. Field ramp 5.3 -> 5.0T, same timing

Jul 29 2005 02:24:49:877PM1050729024Alexandre ParisotRan IWL. nl04 ~ 0.7

Physics Operator Comments
Jul 29 2005 09:03:56:517AM1050729001Joseph SnipesShot 1: Loaded shot 1050629014 and then changed Ip to 0.6 MA, nl04 to 0.6 x 10^20 m^-2, and the TF current to
153 kA. Also added a 3He puff in PG2 from 0.3 to 0.55 s at 100 V. Then loaded segment 1 from 1050728035 to
maintain yesterday's startup. Dud!
Jul 29 2005 09:17:24:410AM1050729002Joseph SnipesShot 2: Increased prepuff by 4 ms to 26 ms duration. Good shot but lots of hard x rays. Seems the gas is
still very low.
Jul 29 2005 09:34:55:673AM1050729003Joseph SnipesShot 3: Increased prepuff by 1 ms to 27 ms duration. Good shot.
Jul 29 2005 09:45:32:220AM1050729004Joseph SnipesShot 4: Try lowering the requested nl04 to 5 x 10^19 m^-2, though it seems that the density is already going
much higher than the requested 6 x 10^19 m^-2. Good shot.
Jul 29 2005 10:03:34:173AM1050729005Joseph SnipesShot 5: Increased RCUR in the rampdown to attempt to avoid the disruption in rampdown. Set nl04 = 4 x 10^19 m^-2
to eliminate the D2 puff between 0.3 and 0.4 s. IGOR ACK failure. No power shot.
Jul 29 2005 10:17:47:347AM1050729006Joseph SnipesShot 6: Try again. Good shot.
Jul 29 2005 10:35:14:300AM1050729007Joseph SnipesShot 7: Moved 3He puff 50 ms earlier to start at 0.25 s and end at 0.5 s to attempt to shut off the D2 puff.
Decreased prepuff by 2 ms to 25 ms duration. No power for unknown reasons!
Jul 29 2005 10:39:06:923AM1050729008Joseph SnipesShot 8: Try again. Good shot.
Jul 29 2005 10:54:32:987AM1050729009Joseph SnipesShot 9: Moved 3He puff by another 50 ms to start at 0.2 s and end at 0.45 s. Also lowered nl04 to 3 x 10^19 m^-2.
Reduced pre-programmed gas slightly before 0.1 s as well. Hard x rays from early in the discharge. Otherwise
it was a good shot.
Jul 29 2005 11:05:06:203AM1050729010Joseph SnipesShot 10: Reloaded segment 1 from shot 8 to hopefully avoid the early runaways at least. Disrupted at 0.6 s.
Jul 29 2005 11:20:48:377AM1050729011Joseph SnipesShot 11: Increased prepuff by 4 ms to 29 ms duration. Disrupted at 1.31 s. Something took a bite out of the
current at 1.15 to 1.2 s as well. There is a big impurity injection at 1.16 s.
Jul 29 2005 11:44:59:300AM1050729013Joseph SnipesShot 13: Reduced nl04 to 2.5 x 10^19 m^-2 to keep the D2 puff off. Disrupted at 0.42 s.
Jul 29 2005 12:04:19:953PM1050729014Joseph SnipesShot 14: Loaded shot 1050615022 into segment 2 and turned on segment 2 and turned off segment 3. Copied Ip, nl04,
TF, and gas waveforms to segment 2 from segment 3. This will be an inner wall limited plasma. Good shot.
Jul 29 2005 12:26:29:797PM1050729015Joseph SnipesShot 15: Reduced RCUR by 6 mm to increase the outer gap for the ICRF. Reduced 3He puff duration to 150 ms
from 0.2 to 0.35 s. Good shot.
Jul 29 2005 12:48:40:643PM1050729017Joseph SnipesShot 17: Reduced Br0 from 0 to -0.5 mT. Reduced 3He puff by 50 ms to 100 ms duration from 0.2 to 0.3 s.
Good shot.
Jul 29 2005 12:56:41:407PM1050729018Joseph SnipesShot 18: Repeat. Disrupted at 0.31 s. Too many runaways.
Jul 29 2005 01:11:39:550PM1050729019Joseph SnipesShot 19: Increased prepuff by 3 ms to 30 ms duration. Also increased pre-programmed D2 gas in segment 1
slightly. Runaways have come way down. Good shot.
Jul 29 2005 01:23:33:127PM1050729020Joseph SnipesShot 20: Repeat. Runaways are back. Otherwise a good shot.
Jul 29 2005 01:42:07:347PM1050729021Joseph SnipesShot 21: Increased prepuff by 2 ms to 32 ms duration. Increased pre-programmed gas slightly in segment 1.
Put a TF ramp from 0.8 s to 1.4 s from 153 kA to 144 kA then constant to 1.5 s. Still got lots of runaways but
it is otherwise a good shot.
Jul 29 2005 01:50:07:097PM1050729022Joseph SnipesShot 22: Increased pre-programmed gas from the first time point to try to eliminate the runaways. Also,
increased the prepuff by 2 ms to 34 ms duration. Reduced TF current to 142 kA from 1.4 to 1.5 s. More
runaways!
Jul 29 2005 02:03:41:750PM1050729023Joseph SnipesShot 23: Increased prepuff by 3 ms to 37 ms duration. Increased pre-programmed gas in segment 1 some more.
Good shot. Eliminated most of the runaways.
Jul 29 2005 02:18:57:050PM1050729024Joseph SnipesShot 24: Ian suggests increasing EF4 by 10 A to help resolve the early bounce, but it seems the vertical field
changed by itself on the last shot. I changed EF4 by +10 A to -1300 A. Set the TF current to 148 kA in segments
1 and 2 until 0.8 s then ramped it to 137 kA at 1.4 s and kept it there until 1.5 s. Good shot.
Jul 29 2005 02:32:29:907PM1050729025Joseph SnipesShot 25: Increased pre-programmed gas in segment 1 a bit more. Changed TF current from 1.4 to 1.5 s to 132 kA.
Disrupted at 0.315 s probably due to an impurity injection.
Jul 29 2005 02:42:28:673PM1050729026Joseph SnipesShot 26: Increased pre-programmed gas a bit more in segment 1. Some hard x rays appear just after segment
switch as the gas shuts off, so I added a short gas puff from PG3 in segment 2 from 0.1 to 0.14 s. Good shot.
Jul 29 2005 03:01:21:877PM1050729027Joseph SnipesShot 27: Repeat. Good shot.
Jul 29 2005 03:07:10:907PM1050729028Joseph SnipesShot 28: Moved pre-programmed gas in segment 1 ahead 3 ms earlier. Added 2 ms to the prepuff to make it 39 ms
duration. Changed TF current to 143.7 kA until 0.8 s, then ramped it to 129 kA. Disrupted at 0.2 s.
apparently due to impurity injections.
Jul 29 2005 03:27:43:750PM1050729029Joseph SnipesShot 29: Increased prepuff by 2 ms to 41 ms duration. Moved pre-programmed gas earlier by 2 ms starting to ramp
up at 0.015 s and reaching its peak at 0.19 s and then increased slightly the other gas points in segment 1.
Disrupted at 0.45 s.
Jul 29 2005 03:31:51:563PM1050729030Joseph SnipesShot 30: Raised nl04 to 3.5 x 10^19 m^-2. Moved A-coil start to 0.25 s reaching maximum current at 0.35 s.
Fizzle!
Jul 29 2005 03:44:27:657PM1050729031Joseph SnipesShot 31: Reloaded segment 1 from shot 1050729028. Try again. Fizzle!
Jul 29 2005 04:00:06:830PM1050729032Joseph SnipesShot 32: Reloaded segment 1 from shot 1050729027. Returned EF4 to -1310 A. Try again. Fizzle!
Jul 29 2005 04:08:56:033PM1050729033Joseph SnipesShot 33: Reduced EF4 by another 10 A to -1320 A. Reduced prepuff by 3 ms to 34 ms duration. Increased Br0
by 0.5 mT to 0 mT. Finally got a good shot again.
Jul 29 2005 04:22:27:737PM1050729034Joseph SnipesShot 34: Changed TF current to 141 kA from 0.1 s to 0.8 s. More runaways! Disrupted just after 1 sec.
