MP 702(first part,half run day): Cold pulse modulation experiments SL: cgao PO: parker This half run day is first part of MP 702. First of all we will try locked mode shot for HiReX velocity calibration (ref: 1120517007). If locked mode is archived, we will move on to have shots with current and density scans with CaF2 injection from 0.7 - 1.5s, 10Hz. put 1.5 psi Ar in B-SIDE-LOWER Target plasma: LSN nl04: varies under different current (see below for details) Ip = 0.55MA, 0.8MA, 1.1MA Bt = 5.4 T ================ Shot Plan =============================================== (1) Locked mode.

The second half (1pm - 6pm) will be an MP for current profile measurements in strong LHCD. MP 705: Current profile measurements in plasmas with Strong LHCD SL: Mumgaard PO: Parker This will be part b and c of the MP as we obtained a good power scan yesterday during the Polarimeter shake-down. The second half runday will be run tomorrow morning where we will finish what we don't accomplish today and revist the power scan. Target plasma: 1120601025. Extend flat top to 1.9s. nl04: 0.3e20 m^-2 Ip = 500kA, vary to avoid MHD, but then run fixed for phase and density scans. Bt = 5.4 T Beam prescription: 16 pulses starting at 0.3s, 75ms on -25ms off, 48-50keV, > 6.5A. Check MSE data between shots, repeat if necessary. ================ Shot Plan =============================================== (0) We will skip the locked mode and use the one just prior on Chi Gao's run. (1) MSE plasma size scan Ref 1120516020. Flatten density. Decrease Ar puff. (2) Establish reliable LH performance at 800-900kW at 75deg phasing, stable density, no MHD, significant current drive and 0.7s LH pulse length starting at 0.7s. (3) LH Phase scan. - 60 deg - 75 deg - 90 deg - 105 deg (4) Quasicontinous LH phase scan. LH 1s long starting at 0.7s. Phase scan from 60-105deg with 5deg changes every 100ms. (5) Shot-to-Shot density scan. LH at 75deg, 0.7s starting at 0.7s, 900kW. - 0.3 nel04 - 0.4 - 0.5 - 0.6 - 0.75 - 0.9 (only if we saw some LH effect in 0.75nel04 shot) (6) Limited discharge. Ref 1100820003 with flattop to 1.9s and LH 0.7s long at 0.7s. (7) Repeat MSE plasma sweep from part 1 ================ Required Diagnostics ================================== MSE-DNB.

Run summary of MP702(first part) We tried 13 shots before the TF crowbar's problem. 3 fizzles: shot 3,7,12. 1 early disruption: 1(runaway shutdown) 1 good locked mode: 4. Disruption at 1.58s, but good enough for HiReX calibration 8 full plasma: 2,5,6,8,9,10,11,13. Of them shot 8,9,10,11,13 are good shots for analysis. The run ended earlier because of the TF problem. (1) Locked mode good locked mode: 1120607004. Planned to have another locked mode the end of the run, but the TF problem stops the run. (2) Ip = 0.8MA. Density scan: Shot 5 - 12. Shot 5,6 the LBO didn't work properly. No injection for some time points. Shot 7 fizzle Shot 8,9: ne_ave~ 0.7. LOC. Co-current rotation. The cold pulse propagation was not purely diffusive, non-local hear transport. Shot 10,11: ne_ave~ 1.0 & 1.1. SOC. Counter-current rotation. But the non-local still existed. Shot 12: Fizzle. Programmed to higher current, but fizzled. Due to time issue, we moved to higher current (1.1MA) (3)Ip = 1.1MA. Shot 13 Shot 13: ne_ave ~ 1.2. LOC. Co-current rotation. Heat transport is non-local. Thanks Prof. Ron Parker for the Phys Op. Thanks all for helping the run. Need to say sorry to Bob, ruined your run...

A disappointing run. The run began with a PO error. The SL requested a locked mode shot for a HIREX calibration and specified a shot. This was loaded by the PO, but only in Segment 2 so that another startup could be used in segment 1. It turned out that the locked mode segment in the SL's shot was in segment 4, not segment 1. The loaded shot resulted in a runaway shutdown. After tuning the gas fill, the shot went off well, but there was no locked mode. The problem of the wrong segment was discovered and fixed for shot 3, which did produce the desired locked mode. In hindsight, the entire shot recommended by the SL should have been loaded, with Segment 1 from a recent startup imported after the SL's shot was loaded. After the locked mode shot, the run followed the run plan and basically completed about 1/3 of it. This was all at 800 kA. The SL then decided to push to 1.1 MA and the first shot ran well, but the TF crowbarred. This was in some way not surprising since noise was showing up on some of the diagnostic waveforms from the relevant convertor cabinet (Converter 2, cabinet 3) in previous shots. After changing out 3 blown fuses caused by the crowbar, the supply was tested at 50, 100 and 150 kA, but again crowbarred during the 150 kA test. This time there were no blown fuses, and various boards were checked that were thought to be related to the problem. After trouble shooting, the TF was again tested. This time it did not crowbar at 150 kA, but the signals used to monitor its performance again showed spikes similar to those originally seen and that were associated with the crowbars. At this point it was decided to hi-pot all 60 SCR's in the cabinet, a procedure which, to do safely, would take several hours. With only 2 hours remaining in the run by then it was decided to scrub it so that work could get on with the hi-potting. Scorecard: 13 plasma attempts, 8 through flattop, 1 runaway shutdown, 3 fizzles and 1 disruption.

Physics Operator Comments
Jun 7 2012 09:12:24:530AM	1120607001	Ron Parker	First shot was a runaway shutdown -- thanks Matt. Next: Add 3 ms pulse gas prefill.
Jun 7 2012 09:38:20:143AM	1120607002	Ron Parker	Shot 2 ran OK, but didn't lock. It turned out that the shot the SL wanted was programmed in segment 4 from 1120517007, not segment 2 which was loaded. The mistake was to load just segment 2 from that day rather than the whole shot. Interestingly, segment 2 did run but didn't have the right A-coils for locking.Next time: load whole shot, then import segment 1 for a better startup, rather than the reverse. Delay while TF power supplies checked -- some spikes appeared in converter #3 cabinet waveforms.
Jun 7 2012 10:35:46:653AM	1120607003	Ron Parker	Shot 3 fizzled
Jun 7 2012 10:36:26:973AM	1120607004	Ron Parker	Shot 4 ran and locked as expected. Now we move on to the rest of the SL's shot plan.
Jun 7 2012 10:54:19:587AM	1120607005	Ron Parker	Shot 5 ran well,disrupting halfway into rampdown. Density was in the range specified, but a) Thomson was not working and b) CaF2 injections were erratic, so we'll try to repeat this shot.
Jun 7 2012 11:10:29:307AM	1120607006	Ron Parker	Shot ran, this time disrupting at ~ 1.25 s after several CaF2 injections. Next: Increased programmed density by 20%, to 4.2e19.
Jun 7 2012 11:18:19:807AM	1120607007	Ron Parker	Shot 7 fizzled, the price to pay after a mid-pulse disruption.
Jun 7 2012 11:38:54:950AM	1120607008	Ron Parker	Shot 8 was OK, still disrupts half way into rampdown. Density had a dip early, which needs to be eliminated if possible. Repeat last shot.
Jun 7 2012 11:53:48:543AM	1120607009	Ron Parker	Shot 9 ran well, useful data. Next: Raise programmed density to 6.5e19 m-2.
Jun 7 2012 12:35:02:420PM	1120607010	Ron Parker	Shot 10 ran well
Jun 7 2012 12:35:15:083PM	1120607011	Ron Parker	Shot 11 ran well.
Jun 7 2012 12:35:30:130PM	1120607012	Ron Parker	Shot 12 fizzled.
Jun 7 2012 01:12:40:030PM	1120607013	Ron Parker	Shot 12 ran, produced good data at 1.1 MA. but TF crowbarred. There will be a delay while TF converter fuses are checked. Fault was triggered in cabinet 3, which was checked after shot 2 when noisy signals had been observed from this cabinet.
Jun 7 2012 01:43:02:823PM	1120607013	Ron Parker	3 Fuses have been replaced, Test shot coming up.
Jun 7 2012 01:49:29:770PM	1120607014	Ron Parker	Shot 14 was a 50 kA TF test shot, all indications normal. Next: Try 150 kA TF test shot.
Jun 7 2012 02:02:32:493PM	1120607015	Ron Parker	Another TF fault and crowbar during the 150 kA test shot. This means we are likely down for at least 1 hour.
Jun 7 2012 02:45:54:740PM	1120607015	Ron Parker	50 kA TF test coming up
Jun 7 2012 03:15:56:593PM	1120607016	Ron Parker	TF test was OK at 50 kA. Try 100 kA test.
Jun 7 2012 03:15:41:250PM	1120607017	Ron Parker	TF test at 100 kA OK. Try 150 kA next.
Jun 7 2012 04:04:59:133PM	1120607017	Ron Parker	It has been decided to hi pot each SCR in converter 2, cabinet 3 since Bill thinks that the problem that we are having with the TF crowbar is a likely to be a bad SCR. This is a time consuming process, likely to take a few hours. So at 4:00 we have decided to scrub the run.
Jun 7 2012 04:09:23:390PM	1120607018	Ron Parker	150 kA shot was OK. But glitches in the reporting waveforms. We'll continue to trouble shoot.
