MP585 Low Bt Discharge Development with 50 MHz ICRF Bt = 3.4 T Examined Ip = 600 and 450 kA, rampup in 500 ms ICRF power up to 3.0 MW (J-port only), but 2.5 MW was better used step ups in ICRF power during rampup beginning at 120 ms early diverts at 100 ms good plasma shaping, kappa about 1.7, gaps were good and steady obtained EDA H-modes in flattop, also some choppy ELM-free cases obtained routine H-modes in rampup beginning at 200 ms, ELM-free bridging of the rampup H-mode to the flattop H-mode was a challenge are those ELMs in the last discharge 032 (J. Rice)?? reliable discharge programming and development allowed us to get much more routine behavior start with Ip = 600 kA 003 ohmic L-mode reference at 600 kA 009, 011, 013 ohmic rampup,H-mode flattop, EDA H-mode, ICRF power up to 2.5 MW in flattop 014 1 MW ICRF in rampup, 2.5 MW in flattop, H-mode in ramp at 200 ms, choppy ELM-free H-modes in flattop 015 1 to 2 MW ICRF in rampup, 2.5 MW in flattop, H-mode in ramp at 200 ms, choppy ELM-free H-modes in flattop 021 1 to 2 to 2.5 MW in rampup, 2.5 MW in flattop, H-mode in rampup at 200 ms, choppy H-modes in flattop 024 1 to 2 to 2.5 MW in rampup, 2.5 MW in flattop, higher density request to try and bridge rampup to flattop H-mode, getting better switch to Ip = 450 kA 028 ohmic L-mode 029 1 MW ICRF in rampup, 2.5 MW in flattop, EDA H-mode in flattop 032 1 to 2 to 2.5 MW in rampup, H-mode in rampup, EDA H-mode in flattop (ELMs?) betaN (600 kA) ~ 1.5 betaN (450 kA) ~ 1.2 Overall a good run day, several full discharges, flattop and rampup H-modes at low Bt = 3.4 T. The Low Bt startup has been married to the early divert, and has resulted in routine production of H-modes in rampup, something that was highly random in the past at these plasma currents. The q95 values are 4.0 at 600 kA and 4.6 at 450 kA. ICRF worked well with long 1.4 s pulses.

A very successful day of low field startup with early diversion. This run puts to rest the superstition that low-field startup is unreliable. We had not a single fizzle even after disruptions with 3T initiation. RIP! Shots had diversion at about 0.1s which was moved somewhat earlier as the day wore on. I found that one problem with early diversion in this setup is that B_R is being controlled until about 65ms in segment 1. This prevents one moving the plasma down to make an early lower divertor. Beware, most shots today are using segments 1 and 3. Don't just import segment 2 and hope you've got the right thing. Reliable H-modes in current ramp were obtained which made the Session Leader happy.

Session Leader Comments
Nov 17 2009 01:30:48:043PM	1091117017	Chuck Kessel	trying ICRF step up, 1-2-3 MW, 3 MW is too high, tripping antenna getting reliable H-mode onset in rampup trying to push this H-mode into flattop with little or no dropout interesting that we are saving V-s and dropping li, but sawtooth onset is not delayed?? need to check this MY ENTRIES HAVE BEEN UNDER AVAILABILITY, SORRY
Nov 17 2009 02:29:49:170PM	1091117019	Chuck Kessel	shots 19, 20, 21 trying to get a final discharge with H-mode in rampup completely blended into flattop varying final ICRF step +/- 50 ms varying gas injection to get EDA in flattop early rampup H-modes make it difficult to get EDA pre-requisite density ICRF pulses are going well discharge reproducibility is very good
Nov 17 2009 03:16:01:757PM	1091117024	Chuck Kessel	good early H-modes in rampup, have reasonable transition into flattop ICRF pulse is good up to 2.5 MW all thru to rampdown disruption in rampdown now we move onto 450 kA
Nov 17 2009 03:47:16:183PM	1091117026	Chuck Kessel	good start at 450 kA fixing up the programming very steady EDA H-mode 0.5 to 1.1 s
Nov 17 2009 03:59:30:967PM	1091117027	Chuck Kessel	getting H-modes in ramp, but these are distorting the Ip ramp due to low Ip H-mode density excursions may be making ICRF trip out lower density
Nov 17 2009 04:10:21:857PM	1091117028	Chuck Kessel	better Ip trajectory no ICRF on that shot, ohmic, L-mode lower density helped

Physics Operator Comments
Nov 17 2009 09:00:58:057AM		Ian Hutchinson	Load from 1090710015, which is the recommended low field startup for that day. Call all predictors. Do so till no warning comes on load. Set Ip to 0.6MA. Nl04 to 0.5e20. Fiddle with async_pros dpcs_fizzle to use shot 1090731017.
Nov 17 2009 09:50:04:090AM	1091117001	Ian Hutchinson	Plasma disrupts at 1.3s. Appears to be vertically unstable. Lower clearin from .012 to .009. Increase zxu to 1cm from 0. Long wait for data system.
Nov 17 2009 09:50:17:137AM	1091117002	Ian Hutchinson	No power shot
Nov 17 2009 10:09:23:637AM	1091117003	Ian Hutchinson	Load segment 2 from 1090911030 which is the early divert shot, but needs some more adjustment, into segment 3. Call predictors. Set Ip to .6MA in seg 3. Import seg 1 from 1090911030 to seg 4. Call predictors. None of this is active yet. Go ahead with shot, since data system might be fixed.
Nov 17 2009 10:21:39:777AM	1091117003	Ian Hutchinson	Plasma to rampdown. Seg 3. Nl04 to .5e20. zcur kept at -.005 versus ramping to zero. OH1V to 200V at seg switch. Turn on Seg 3 instead of Seg 2.
Nov 17 2009 10:50:13:073AM	1091117004	Ian Hutchinson	Plasma to rampdown! Unfortunately Bt was wrong and ramped up to 5.4T Set TF current to 93500. Add rcur point at .15s at .665 (vs .662). Set nl04 to .5 at .13s.
Nov 17 2009 10:50:35:310AM	1091117005	Ian Hutchinson	Plasma to rampdown. Enable Ar at 50ms puff. Ramp zcur to ~0 so as to keep kappa at >1.7 Tweak rcur out at .2s

Nov 17 2009 11:30:23:747AM	1091117008	Ian Hutchinson	Plasma to rampdown. Startup bounces improved. OH1V to 100V at .13s try to prevent the overshoot on clearin. nl04 to .7e20
Nov 17 2009 11:43:06:900AM	1091117009	Ian Hutchinson	Plasma to rampdown. The OH1V is the right knob. Clearin overshot is moderated. OH1V move last 200V to .1s from .12s
Nov 17 2009 11:58:50:450AM	1091117010	Ian Hutchinson	Plasma disrupts at .65s. Big radiative event. Clearin overshoot mostly fixed. OH1V to 50V at .13s. Clearin integral to 1. early.
Nov 17 2009 12:08:36:260PM	1091117011	Ian Hutchinson	Plasma to rampdown. Raise zxl at .3s on to move strikepoint on to plate earlier. Set zcur to -.008 at .125s. Set OH2u/l voltage to 70V at .04s (from 80V).

Nov 17 2009 12:42:58:150PM	1091117013	Ian Hutchinson	Plasma to rampdown. EF1L voltage to 100V at .08s in segment 1. This asymmetrizes EF1s.
Nov 17 2009 12:55:52:340PM	1091117014	Ian Hutchinson	Plasma to rampdown. The volt-seconds used in rampup is substantially reduced by the RF injected (c.f. shot 13).
Nov 17 2009 01:15:37:120PM	1091117015	Ian Hutchinson	Plasma to rampdown. Decrease EF1u/l voltage in segment 1, and resymmetrize. Speed up the segment 1 chopper ramp.

Nov 17 2009 02:13:23:480PM	1091117020	Bill Rowan	020. Disruption at 0.7s. Looks like an injection. Next shot. No PCS changes
Nov 17 2009 02:19:05:467PM	1091117021	Bill Rowan	021. Plsama through the ramp down. several h-modes. Next shot Ian back
Nov 17 2009 02:46:40:513PM	1091117022	Ian Hutchinson	Gas puff of 42V programmed from .2 to .4s. EF1V to 0V at .065s Plasma to rampdown. Gas puff 100V from .2 to .4s. OH1V to 50V at .115s

Nov 17 2009 03:36:32:170PM	1091117025	Ian Hutchinson	Plasma disrupts at .98s. Failed to reduce the current because of making change to segment 2 rather than 3. Make real Ip change. Make real EF1V change. Looks like OH1V was properly entered.
Nov 17 2009 03:50:31:933PM	1091117026	Ian Hutchinson	Plasma disrupts at 1.24s Start zcur ramp at 60ms vs 70ms in seg 1. Make seg3 OH1 voltage ramp earlier. EF1V to -50V
Nov 17 2009 04:02:51:717PM	1091117027	Ian Hutchinson	Plasma disrupts at .68s Remove nl04 voltage puff and lower early nl04 point. EF1V to -100V seg 1.
Nov 17 2009 04:20:12:983PM	1091117028	Ian Hutchinson	Plasma to rampdown. Ramp zcur faster in seg 1 and 3. EF1V to -200V.
Nov 17 2009 04:28:02:967PM	1091117029	Ian Hutchinson	Plasma to rampdown. The bizarre startup is caused by having copied the EF2 voltage into the EF1 trace! Now EF2V are at -200V. EF1V to -150V.
Nov 17 2009 04:42:03:387PM	1091117030	Ian Hutchinson	Plasma to .88s. Turn nl04 gain down to 1 at .25s. Add a preprogrammed 10V puff instead. OH1V to 350V at .072s (small increase).
Nov 17 2009 04:53:56:857PM	1091117031	Ian Hutchinson	Plasma to rampdown. Import segment 3 into segment 2. Turn off seg 3. Turn on seg 2. Remove gas puff and put gain back into nl04 at .7e20. Start segment 1 zcur ramp at .065s.

good discharge, ran all thru rampdown plasma shape good level trajectories of li, gaps, q95, etc in flattop divert at 120 ms ICRF is warming up

Nov 17 2009 11:14:15:467AM

good discharge ICRF gave 1.5 MW in flattop, H-mode(s) begin soon after end of rampup density is low so lots of ELM free H-modes q95 = 4, kappa = 1.7, li(H-mode) = 1.25 getting close to H-mode flattop baseline, will raise density next radiation bursts are occuring

good discharge flat ICRF at 2 MW EDA-ish H-modes can't track radiated power not sure if plasma outer strike pts are creating problems with injections or not

Nov 17 2009 12:31:14:370PM

OK, have ICRF up to 2.5 MW in flattop getting EDA-ish H-modes density set for H-mode in flattop high radiation or something is affecting discharge will begin ICRF in rampup next

Nov 17 2009 12:55:31:073PM

GREAT, got an H-mode forming at 200 ms Good ICRF, 1 MW at 120 ms then 2.5 at 500 ms really heated electrons early li drops significantly at H-mode onset back transition at 350 ms, since ICRF level at 1 MW
