1. Establish discharge using 1091112034 as a basis with 2.5 MW from D+E antennas and 2.5 MW from J in heating phase. (10 shots) Neon may be needed to limit injections and faults. Raise plasma current to avoid H-mode if needed. Scan density down to maximize fast ion energy. - monitor Prad/Mo brightness Scan 3He to minimize mode conversion and maximize ion energy. 2. Using developed discharge, scan the J antenna phase with 2.5 MW from D+E, 2.5 MW from J antenna, Ip=0.8 MA and BT~5.5->5.7 T. (6 shots) 3. Scan the J antenna phase in discharges with 2.5 MW from D+E, 1.5 MW from J antenna, and BT~5.5->5.7.(6 shots) 4. Once the critical BT field is identified, perform power ramp to assess power required for sawtooth pacing for fixed BT. Compare different antenna phases (6 shots). 5. Repeat 2 for Ip=1 MA and 1.3 MA time permitting.

We were able to make good progress investigating sawtooth stabilization/destabilization with 3He minority absorption near the q=1 surface. We completed a phase scan with He monitor indicating ~100 a.u. concentration and PCI saw no evidence of mode converted waves. For -90deg phasing (waves in counter current direction), the sawteeth grew larger with the 3He resonance inside the q=1 surface and shorter with the resonance outside the q=1 surface. For +90deg, the response was opposite with sawteeth short then becoming long. The amplitude was also smaller for +90deg. Heating phasing behaved similarly to +90deg. This phase dependence is opposite from central H minority heating where the sawtooth period can be lengthened/shortened. This suggests the mechanism is not diffusion of fast particles in space. We also attempted to scan He3 fraction to lower concentrations but ran out of time - we lost several discharges to locked modes, MARFEs, and ratty RF performance. An interesting observation is that the neutron rate was highest for heating phase, next +90deg phase, and the lowest was -90deg phase. In the future we would like to complete the He3 scan to lower concentration, with lower Zeff, power scan, and larger initial sawteeth.

Run summary for Monday 2009/11/23 MP588 - Evaluation of ICRF sawtooth pacing techniques Session leaders: S. Wukitch Physics operator: R. Granetz The tokamak ran reasonably well today. The ICRF also ran well, with a clean 5 MW on nearly all shots, perhaps thanks to the neon puffing that we were doing. There were several operational issues today which rendered the data less than stellar. There was a persistent high level of hard x-rays early in the discharge, which seems to be an ongoing problem in the last few weeks. None of the PG3 gas tweaks or voltage programming tweaks that we tried today did any good. Eventually we found that raising the pre-fill enough (to about 35 ms or more) solved the problem for a while, even though this has not worked so well on other recent run days. We also had a curious locked mode problem on a few shots for reasons that we didn't understand, and there were large marfes on a number of shots that caused undesirable cooling. I also made some physop errors, including not loading one change, and changing the Ne/Ar pulse duration instead of the He3 pulse duration on two shots. Scorecard: 31 plasmas 0 duds 3 fizzles 0 power supply tests 0 no-power MDS shot cycles -------------- Total: 34 shot cycles

Physics Operator Comments
Nov 23 2009 09:18:11:740AM		Robert Granetz	Additional last-minute tweaks made to first shot: - decrease He3 puff duration to 100 ms, starting at t=0.3 s - set nl_04 to 0.7e20 m-2
Nov 23 2009 09:19:38:550AM	1091123001	Robert Granetz	Shot 01 -- Fizzle. I loaded the startup from the end of Friday, which must have been running with the cryopump. Today we're not using the cryopump, so the pre-fill was much too high. Next shot: reduce pre-fill pulse to 27 ms; also reduce PG3 gas programming in seg 1
Nov 23 2009 09:22:24:753AM	1091123002	Robert Granetz	Shot 02 -- Fizzle. Somehow I didn't properly load the change to the pre-fill. The change to PG3 did load properly. Physop error. Next shot: load the correct prefill pulse this time (27 ms)
Nov 23 2009 09:41:24:253AM	1091123003	Robert Granetz	Shot 03 -- Plasma, full length. Upper null; 0.8 MA, 5.6 T, 0.7e20 m-2. Prf=5.0 MW from D,E, & J. One short H-mode. Neon is not yet turned on. Next shot: no DPCS changes; Steve is changing the RF waveforms a bit

Nov 23 2009 10:12:50:817AM	1091123005	Robert Granetz	Shot 05 -- Plasma, full length. 0.8 MA, 5.6 T, USN. Prf=5.1 MW. 3 short H-modes. Lots of early hard x-rays on this shot, unlike the previous shots today. Neon is being puffed starting at t=0.4 s. Next shot: program a small ramp up to 5.8 T in Btor starting at t=1.2 s
Nov 23 2009 10:22:05:990AM	1091123006	Robert Granetz	Shot 06 -- Plasma, full length. 0.8 MA, 5.6 T with a small ramp to 5.73 T; USN; neon puffing. J-port faulted alot. Lots of hard x-rays, but less than the previous shot. Next shot: no DPCS changes; repeat to get better J-port performance
Nov 23 2009 10:43:05:660AM	1091123007	Robert Granetz	Shot 07 -- Plasma, nearly full length. 0.8 MA, 5.6 T with a small ramp to 5.73 T; USN; neon puffing. Prf=5.1 MW; D,E,J all ran very well. Some early hard x-rays. Next shot: tweak the late Btor ramp; also increase CLEARIN by 3 mm (and increase RCUR by 1.5 mm to keep outer gap unchanged)
Nov 23 2009 10:57:39:957AM	1091123008	Robert Granetz	Shot 08 -- Plasma, full length. 0.8 MA, 5.6 T with a small ramp to 5.75 T; USN; neon puffing. Prf=5.0 T; nice RF performance. Sawteeth are noticeably longer. Marfe went away. Next shot: tweak late Btor ramp up a little more
Nov 23 2009 11:07:56:690AM	1091123009	Robert Granetz	Shot 09 -- Plasma, nearly full length. 0.8 MA, 5.6 T with a small ramp to 5.84 T; USN; neon puffing. Prf=5.0 MW; nice RF performance; lots of early hard x-rays...these seem to come and go randomly fro shot-to-shot Next shot: no DPCS changes; Steve is switching RF phasing
Nov 23 2009 11:22:57:817AM	1091123010	Robert Granetz	Shot 10 -- Plasma, nearly full length. 0.8 MA, 5.6 T with a small ramp to 5.83 T; USN; neon puffing. Prf=5.0 MW; some faulting on J; lots of early hard x-rays; big marfe is back Next shot: add 0.5 psi of argon to the B-side-lower plenum; tweak nl_04 to 0.65e20 m-2
Nov 23 2009 11:30:22:380AM	1091123011	Robert Granetz	Shot 11 -- Plasma, disrupted at t=0.68 s, before any RF turns on. Argon? Next shot: disable B-side-lower
Nov 23 2009 11:48:56:317AM	1091123012	Robert Granetz	Shot 12 -- Plasma, nearly full length. 0.8 MA, 5.6 T with late ramp to 5.83 T; USN. No neon (or argon) puffed on this shot. No marfe. No early hard x-rays. Next shot: turn B-side-lower valve back on, but shorten the pulse to 100 ms
Nov 23 2009 11:58:09:427AM	1091123013	Robert Granetz	Shot 13 -- Plasma, full length. 0.8 MA, 5.6 T with late ramp to 5.83 T, USN, neon puffing (w/some argon as well). Prf=5.0 MW. Huge early hard x-ray signal, even though the previous shot had none. There was a curious unidentified high-Z injection at t=0.69 s Next shot: increase prefill puff by 3 ms
Nov 23 2009 12:08:26:910PM	1091123014	Robert Granetz	Shot 14 -- Plasma, disrupted early in rampdown. 0.8 MA, 5.6 T with late ramp to 5.83 T, USN, neon. Large early hard x-ray signal. Prf=5.0 MW Next shot: no DPCS changes; Steve will change RF phasing
Nov 23 2009 12:23:21:973PM	1091123015	Robert Granetz	Shot 15 -- Plasma, nearly full length. 0.8 MA, 5.6 T with late ramp to 5.83 T, USN, neon Next shot: add 3 more ms to pre-fill; tweak nl_04 down to 0.6e20 m-2 I have to leave for a short dental checkup. Jim Irby is taking over as physics operator for about an hour.
Nov 23 2009 12:44:19:100PM	1091123016	Jim Irby	Plasma into rampdown
Nov 23 2009 12:59:38:050PM	1091123017	Jim Irby	changes -------------------------------- no dpcs changes --- just changing antenna phasing results -------------------------------- plasma into rampdown --- hards early --- beautiful rf traces; 5 MW
Nov 23 2009 01:10:41:380PM	1091123018	Jim Irby	changes -------------------------------- no dpcs changes results -------------------------------- plasma into rampdown --- hards worse
Nov 23 2009 01:23:01:677PM	1091123019	Jim Irby	changes -------------------------------- ef4 from -1290 to -1280 A -- tweak for hards? loaded results -------------------------------- plasma into rampdown
Nov 23 2009 01:27:12:333PM	1091123019	Robert Granetz	Shot 19 -- Plasma, full length. 0.8 MA, 5.6 T with late ramp to 5.80 T, USN, neon. Huge early hard x-ray signal, but actually better than the previous shot. Prf=5.0 MW. I'm back as physics operator after this shot. Next shot: no DPCS changes
Nov 23 2009 01:50:38:473PM	1091123020	Robert Granetz	Shot 20 -- Plasma, but disrupted at t=0.37 s. The cognescenti claim it's a locked mode. Next shot: add early gas via PG3 programming
Nov 23 2009 01:59:25:363PM	1091123021	Robert Granetz	Shot 21 -- Plasma, disrupted at t=0.72 s. This looks like a locked mode...no sawtoothing. Next shot: tweak early gas programming and nl_04 programming between 0.2 and 0.3 s.
Nov 23 2009 02:10:25:660PM	1091123022	Robert Granetz	Shot 22 -- Plasma, full length. 0.8 MA, 5.6 T with late ramp to 5.83 T, USN, neon. Prf=5.0 MW. Fewer early hard x-rays. Next shot: reduce Ne/Ar puff duration to 75 ms
Nov 23 2009 02:28:39:440PM	1091123023	Robert Granetz	Shot 23 -- Plasma, full length. 0.8 MA, 5.6 T with late ramp to 5.83 T, USN, neon. Prf=5.0 MW. Bad startup...almost choked. Next shot: add -10 A to IC_EF4 (i.e. set to -1290 A); decrease Ne/Ar puff to 60 ms
Nov 23 2009 02:40:34:707PM	1091123024	Robert Granetz	Shot 24 -- Plasma, full length. 0.8 MA, 5.6 T with late ramp to 5.83 T, USN, neon. On this shot and the preceding shot I decreased the Ne/Ar puff, but Steve actually wanted me to decrease the He3 puff. Another physop mistake. The startup was much better, although the early runaways are bad. Next shot: reduce He3 pulse to 60 ms, and set the Ne/Ar puff back to 100 ms; also tweak early EF3 preprogrammed voltage as suggested by Steve Wolfe
Nov 23 2009 02:54:22:130PM	1091123025	Robert Granetz	Shot 25 -- Plasma, full length. 0.8 MA, 5.6 T with late ramp to 5.83 T, USN, neon. Prf=5.0 MW. Huge early hard x-rays, so the EF3 voltage tweak didn't help. Next shot: disable the He3 valve (B-side-upper); tweak early OH1 voltage programming as suggested by Steve Wolfe
Nov 23 2009 03:07:31:957PM	1091123026	Robert Granetz	Shot 26 -- Plasma, full length. 0.8 MA, 5.6 T with late ramp to 5.83 T, USN, neon. Lots of faulting on J-port. Huge early hard x-ray signal, so the OH1 voltage tweak didn't do anything. Next shot: turn He3 valve back on (B-side-upper); start the late Btor ramp a little earlier (t=0.9 s) to try getting to 6.0 T
Nov 23 2009 03:30:05:690PM	1091123027	Robert Granetz	Shot 27 -- Plasma, nearly full length. 0.8 MA, 5.6 T with late ramp to 5.96 T, USN, neon. Prf=4.7 MW, but J turned off early. No early hards! This shot had a locked mode until the RF turns on. Next shot: tweak early nl_04 programming to try avoiding the early locked mode; add 3 more ms to pre-fill
Nov 23 2009 03:42:35:800PM	1091123028	Robert Granetz	Shot 28 -- Plasma, disrupted during rampdown. 0.8 MA, 5.6 T with late ramp to 5.96 T, USN, neon. Prf=5.0 MW. No early hard x-rays. Sawteeth don't start until t=0.45 s. Next shot: a bit more tweaking of early nl_04
Nov 23 2009 03:52:48:317PM	1091123029	Robert Granetz	Shot 29 -- Fizzle. Looks like too much pre-fill. Next shot: reduce pre-fill by 3 ms
Nov 23 2009 04:08:26:537PM	1091123030	Robert Granetz	Shot 30 -- Plasma, disrupted at t=0.91 s. I think it was a low-Z injection. Prf=5.0 MW at the time of the disruption. Next shot: repeat, no changes
Nov 23 2009 04:23:01:067PM	1091123031	Robert Granetz	Shot 31 -- Plasma, full length. 0.8 MA, 5.6 T with late ramp to 5.96 T, USN, neon. Prf=5 MW, but with lots of faulting on J. No hard x-rays. Next shot: no DPCS changes
Nov 23 2009 04:36:53:100PM	1091123032	Robert Granetz	Shot 32 -- Plasma, disrupts late in rampdown. 0.8 MA, 5.6 T with late ramp to 5.96 T, USN, neon. There was a big marfe for most of the flattop. Next shot: reload shot 9 into all segments, shorten the He3 pulse to 60 ms and the Ne/Ar pulse to 100 ms
Nov 23 2009 04:48:58:197PM	1091123033	Robert Granetz	Shot 33 -- Plasma, full length. Looks like a good repeat of shot 9, including high Te and high neutron rate, and no marfe during most of the flattop. 0.8 MA, 5.6 T with late ramp to 5.84 T, USN, neon. Prf=5.0 MW. Huge early hard x-ray signal. Next shot: no DPCS changes; Steve will change the RF phasing
Nov 23 2009 05:01:20:637PM	1091123034	Robert Granetz	Shot 34 -- Plasma, full length. 0.8 MA, 5.6 T with late ramp to 5.84 T, USN, neon. Prf=5.0 MW, but J was faulting for the first part of its pulse. Really huge hard x-ray signal. End of run
