MP575 Run Plan 1091006 Reference discharge 1090911030, ohmic discharge with long rampdown phase Ip = 1.3 MA at 550 ms Bt = 5.4 T Flattop is 0.55 to 1.2 s (2009 rampdown reference 1080409016) Modifications: - nl04 target is 1.3e20 at 700 ms - Bt is 5.4 T through to 2.0 s - flattop Ip is from 550 ms to 1.0-1.2 s - maintain diverted plasma to 1.95 s, large bore if it's ramping down, then start adjusting the rcur and clearing rampdown programming to keep it diverted and closer to the antenna longer - target end of rampdown Ip is 100-200 kA - 2-3 MW ICRF injection at 650 ms, off at 1.0 s - MAYBE: neon injection, see how flattop H-modes behave: Use 1psi neon in B-side lower, puff from .6 to .8sec. NO Argon Tweak at neon puff, rf, nl04(?) in flattop to get as steady/reproducible EOF condition as we can. Maybe have D2 in the NINJA plenum so we can try supplementing the fueling with that if the rf likes it better, as suggested in Wukie's MP581. Establish as reliable as possible flattop H-Mode to initiate rampdown Establish ohmic rampdown reference case with power termination at EOF 1) rampdown (t = 1000ms to 1950ms) 1 MW injection fixed through rampdown (to Ip or n permissible on ICRF) 2 MW (1000ms to 1500ms), and 1 MW (1500ms to 1950ms) 3 MW (1000ms to 1333ms), 2 MW (1333ms to 1667ms), 1 MW (1667 ms to 1950 ms) P(ICRF) to 0 MW at 1333ms (starting power at EOF TBD from above discharges) 3 MW from EOF to 1333ms 2 MW from EOF to 1333ms 1 MW from EOF to 1333ms P(ICRF) to 0 MW at 1500ms 3 MW from EOF to 1500ms 2 MW from EOF to 1500ms 1 MW from EOF to 1500ms P(ICRF) to 0 MW at 1667ms 3 MW from EOF to 1667ms 2 MW from EOF to 1667ms 1 MW from EOF to 1667ms 2) above with 0.5 s rampdown 3) above with 1.5 s rampdown

MP575 ITER-like Rampdown Experiments Successfully set up new baseline discharge for rampdown experiments incoporating: -nl04 target higher density by 700 ms -Bt steady at 5.4 T to 2.0 s -maintain diverted plasma to 1.9+s, holding inner and outer gaps steady to about 1.8 s -target rampdown Ip of 100-200 kA -Ip flattop 0.55 to 1.2 s, beginning of rampdown at 1.2 s, end of rampdown at 1.95 s had difficulties with injections, appearing as large spikes in radiated power some computer problems many discharges to get ICRF conditioned and/or until we used neon to make everything better, however this seemed to wear off H-modes during rampdown 002 ohmic full thru rampdown 003 ohmic full thru rampdown 008 ICRF (very choppy) full thru rampdown H-mode into rampdown 009 similar to 008 with H-mode terminating at 1.1 s 014 ICRF (improving, choppy) full thru rampdown 015 ICRF ramping down in Ip rampdown, full thru rampdown 020 neon added, ICRF 2.2 MW in flattop, drops to 0.75 MW at 1.2 s choppy H-modes, full thru rampdown 022 neon added, ICRF 2.5 MW to 1.5 MW to 0.75 MW not full discharge ends at 1.8 s 023 L-mode, no ICRF not full discharge ends at 1.65 s 025 turn neon off, Prad high ICRF 2MW to 0.75 MW Long H-mode into rampdown out to end of discharge not full discharge ends at 1.65 s Overall, it was a tough run day. It was difficult to get systematic scan of controllable quantities, such as ICRF power. However, there are extreme cases for comparison, and discharges with H-mode well into the rampdown. Radiated power spikes plagued us all day, as well as vertical position control problems in the very early startup phase. Discharge setup proved to be a constant problem rather than fix and forget.

This was a relatively difficult day from the physop point of view. The startup was quite vertically unstable around 100 msec, and quite a few shots were lost vertically at that time. Various tweaks seemed to be helping, but in the end it was not clear. Why some shots seemed fine, while others lurched strongly at or shortly after segment switch (80 ms) was also unclear. A few shots had full rampdown from 1.3 MA, some with H-mode at and even well into rampdown. EF1's were hitting their limit (5 kA) late in flattop for most of the shots that made it that far. Shot 7 had no EF4, shot 12 had no OH2's. Shot 11 was a complete stealth shot (no power supplies, no gas). Shot 6 was a no-power shot (data system hang in init). We tried neon puffing to improve the H-modes/RF; it did not obviously help, and may have increased the probability of disruptions, both in flat-top and during the ramp-down. plasmas 26 (11 of which made it at least part way into rampdown) power supply duds 3 no power 1 cycle test 1 total cycles 31

Oct 6 2009 09:20:45:067AM	1091006002	Chuck Kessel	great first shot, all the way thru good repro of 1090911030 Bt out to 2 s nl04 target set 1.3e20 at 700 ms left gap held longer ef1 reaching limits
Oct 6 2009 09:29:00:723AM	1091006003	Chuck Kessel	repeat 002 with ICRF to get it conditioned no ICRF power good repeat of 002
Oct 6 2009 09:51:22:757AM	1091006004	Chuck Kessel	ugh attempt to repeat 002 with ICRF power early plasma vertical motion around divert time high radiated power, injection? at 120 ms
Oct 6 2009 11:34:19:550AM	1091006008	Chuck Kessel	good recovery early start up behavior much better left gap is held out to 1.85 s nice long H-mode in flattop even with low ICRF power ICRF is choppy, problem with E, fix in progress
Oct 6 2009 11:52:42:613AM	1091006009	Chuck Kessel	good shot all the way thru H-mode in flattop, ends before rampdown ICRF choppy, getting better need more power to get Te up and lower li to start rampdown outer gap is very good held steady out to 1.8 s Zeff/Zave staying low in rampdown while ne is staying high as Ip drops ECE's are cutoff during H-modes
Oct 6 2009 12:22:26:380PM	1091006010	Chuck Kessel	discharge going OK, then disrupts about 1.35 s, injection? radiated power a bit higher than 008 and 009 first H-mode killed by radiation 2nd H-mode occurs even after ICRF turns off Zeff/Zave a bit higher after ICRF
Oct 6 2009 01:47:19:287PM	1091006014	Chuck Kessel	014 and 015 choppy H-modes early with better H-modes later 015 ICRF extending into rampdown lots of radiation with injections during ICRF discharges going thru rampdown
Oct 6 2009 03:23:25:117PM	1091006020	Chuck Kessel	020 and 022 getting ICRF step downs in rampdown, not exactly on purpose, but thats OK H-modes into first half of rampdown li rise delayed compared to L-mode discharges neon helping ICRF, but may be getting slow increase in overall radiation discharges not all the way thru
Oct 6 2009 04:05:51:197PM	1091006025	Chuck Kessel	025 SUPER ICRF pulse long H-mode in rampdown, correlated slower li rise compared to 014/015 radiated power in rampdown similar to older no neon shots 014/015 neon is off injections here and there
