MP132 ICRF H-modes with Boron. MP134 SOL profiles with H-Mode. #2

SL: Takase
PO: Hutchinson
EO: Bertolino/Daigle

Objectives:
1. Get enough consistent shots at 1.1, 0.8MA to give Ti profiles at
a density at the low end (ELMfree) and the high end (ELMY) of H-mode.
2. Implement divertor sweeping (better divertor profile, reduce Moly).
3. Try 1.2MA at slightly higher field.

Jim Irby's note on boronization prior to run:
The boronization was completed at 0600 this morning. We deposited
2.4 times as much boron this time compared to the last boronization
run (somewhere).

RF overloaded on the fiducial shot (shot 02) because of too much loading
(gassed-up antenna?). The first few shots of the day had long H-mode,
but the H-factor wasn't high. It took several shots to get good H-factors.
Sweeping of the strike point was implemented to get better profiles at the
divertor and to spread the heat flux.

Profile scans at "low" (target nel_04=0.9) and "high" (nel_04=1.3) density
were performed at 1.1MA and 0.8MA. The "low" density scan at 1.1MA was
not completed because of repeated disruptions (q was just above 3 because
the inner and outer gaps were relatively large). It was quite clear that
the target density had to be nel_04>=0.9 to get H-mode at 1.1MA.
Some data were also taken at low density at 1.0MA.

On shot 22, we took a baseline shot for diamagnetic measurements.
With the baseline subtraction, W_dia agreed with W_EFIT very well,
but discrepancy started developing around shot 26. The cause of
this discrepancy is under investigation.

On shots 39 and 40 gas puffing during H-mode was attempted with fill valve
(shot 39) and with NINJA (shot 40), but RF did not stay on.
Objective 3. was not pursued.

Physop Summary 960130
_____________________
MP132 ICRF H-modes with Boron. MP134 SOL profiles with H-Mode.(Continued)

Plan
____
Get enough consistent shots at 1.1, 1.0, 0.8MA to give Ti profiles
at a density at the low end (ELMfree) and the high end (ELMY) of H-mode.
Try scanning the strike-point to lower the local divertor energy and
get more detailed profiles.

Summary
_______
Basically completed the plan, except without a high density case at 1MA.
RF did not exceed about 2MW today but was fairly reliable at that level.
Used an RXL sweep throughout to sweep the strikepoint and keep the power
spread out on the divertor. This seemed to work just fine.
The first about 6 shots showed steady improvement in stored energy
and dropping Prad.
Discovered that most of the early Mo influxes observed on shots from
13 on are caused by minor disruptions. They arise when the recycling
is less because of lower density operation. They can be compensated by
higher gas puff but this was not done till the end of the run . Use
shot 40 as an example for future settings at 1.1 MA.
Shots 37 on have the RCUR offset fixed to 3000 in segment 2. This is about
the right value to give a position that is independent of Ip.
Highly robust startup. 39 fizzle-free shots (new Record).
Repeatable/Notable shots:
6-9,10 High density 1.1MA.
14,18,20 Lower density 1.1MA
22 Diamagnetism baseline shot.
27,30,31 Lower density 1.MA
32-34 lower density 0.8MA
35,37,38 higher density 0.8MA
39 B-top gas puff during H-mode.
40 Ninja puff during H-mode.
ELM-free cases were obtained at lower density but did not exceed the stored
energy on the higher density cases because of worse radiation.

Details
_______
Load from 960116037. (11ms fill puff)
1 OH test.
2 OK Fiducial but No RF. Mo at .75s seems caused by RF. Arc suspected.
Load 960125028 Install RXL ramp (.6s,-.005), (.8s,+.02), (1.s,-.005).
Argon 2psi, 20ms.
3 OK Mo rise at RF turn on, but pumps out as the Halpha lump is present.
density rather higher than programmed. Signs of nearly an Ohmic Hmode.
Increase RXL sweep. Make end at 1.1s since RF stays on.
4 OK Disrupts at 1.5s on ramp down. Big radiative increases at RF turn-on.
These are Mo injections.
Slightly more sweep -.007 to +.007.
5 OK More steady Mo accumulation, then pump out. Divertor sweep? 157kJ
Start of reproducible shots. Repeat
6 OK 192kJ. Seems to be continuously improving.
Turn on RF r-feedback with gain -1000. It was off.
7 OK Nice reproducibility of RF at 2MW. 193kJ.
8 OK Slightly more radiation. Mo injection at .86s. 197kJ.
RF off at 1s for earlier probe scan.
9 OK 202kJ.
nl04 to .7 (but forgot to load).
10 Dis at .29s. Hit by a brick at .263s.
11 OK Density did not drop much. Had forgotten to load.
End of fairly high density reproducible 1.1MA shots.
nl04 to .6 early. Loaded.
12 Ok 160kJ. Some Mo injections during RF
nl04 ramp reduced to .55. RXL to maximum .008 from .006.
Start of disruptions at .9s presumably because of lower gas etc.
13 OK Small injections early. 178kJ.
nl05 to .55
14 OK 173 kJ but clobbered by radiation and RF trip.
Argon off. RF feedback to -1500 to help avoid trips.
15 OK No H-mode.Disrupts in ramp down with radiation rising just prior.
Argon on.
16 Dis At 1.09s. No H-mode.
Increase nl04 to .7 and added a safety ramp later.
17 Dis Strike at 1.17s. Bricks at .82s kills H-mode, and 1.15s.
Early Mo injections. Poor current rise.Very good confinement till hit.
18 OK ELM free. Poor current rise. Horrendous accumulation. 177kJ.
19 OK No H-mode. Disrupts at 1.24s. Mo injection at .55s.
Tweak early nl04 up.
20 OK ELM-free. 187kJ Radiation death.
First nl04 point to .7 (upward tweak).
21 Dis At 1.2s. Dropped out of H-mode.
Disable gas and TF Fiz-detector Diamagnetism baseline.
22 Dud
23 OK Big nasty at .3s. NO H-mode. Disrupts at 1.24s.
24 Dis at .7s. Injections.

Ip to 1.MA, nl04 to .9. TF invert to 1.2s.

26 OK Fixed the early disruptions. 160kJ. Halpha bump.
nl04 to .7.
27 OK Early disruptions return but at .1s. Mo Radiation is worse. Clearly
the early Mo bursts are attributable to these disruptions.
28 OK Still at . 1s.
29 Dis At.73s. Early disruption gone but still incipient.
This disruption appears caused by loss of interferometer and hence
feedback. Gas shut off hard at .11s
30 OK Multiple ELM-free H-modes with lots of radiation.
Realized earlier attempts to raise the early gas were bogus. Wrong
segment. Really raised segment 1 this time.
31 OK ELM-free accumulation. Early disruptions.

Ip to .8MA, raise early gas. (nl04 is at .7)
32 OK Long steady state H-mode with small Ha bump. Only incipient early
disrupts. 120 kJ.
Raise early gas.
33 OK Early disrupts. OK H-mode.113kJ.
Raise early gas.
34 OK Early disrupts. 115kJ

Raise early gas. nl04 to 1.5
35 OK RF came on late. 100kJ. Mo low. Only small disrupts.
Fixed the rcur offset to 2000 at segment switch.
36 OK Large increase in early Halpha light. Presumably recycling. No RF.
Segment 2 offset to 3000.
37 OK H-mode.
38 Ok H-mode. 99kJ.
Load Ip=1.1MA. nl04 to .7. Program gas at .65-1.0s 50V gas valve 4
this is the fill valve

41 Fiducial. OOPS! Forgot to load into model. Sorry! Repeated instead.

Session Leader Comments
Jan 30 1996 08:33:30:910AM		Yuichi Takase	MP132 ICRF H-modes with Boron. MP134 SOL profiles with H-Mode.#2 1. Get enough consistent shots at 1.1, 0.8MA to give Ti profiles at a density at the low end (ELMfree) and the high end (ELMY) of H-mode. 2. Implement divertor sweeping (better divertor profile, reduce Moly). 3. Try 1.2MA at slightly higher field.
