Session Leader Plan for 1100812 (am) Session Leader: G. Wallace Physics Operator: R. Parker Miniproposal: 605 LH2 Lower Hybrid Launcher Checkout and Conditioning The purpose of this half day will be to make sure the LH system is operating properly after fixing several issues over the maintenence days early in the week. Also, we will attempt to get Andrea's square wave modulation waveform working. LH Setup: 0.5 mm behind limiter, up to 140 kW/klystron, steady pulses and modulated pulses, 90 & 146 deg phasing. Reference shot: 1100804007 1) Verify proper phase and amplitude of klystron 4 in dummy load. (Before 9am?) 2) Attempt to couple steady LH pulse at 146 deg, 40 kV, 80 kW/klystron. If necessary adjust phasing/amplitude on klystron 4 if necessary. Adjust plasma density, gaps, and launcher position to achieve lowest reflection coefficients on columns which generate trips. If successful increase power to 110 kW/klystron, then 140 kW/klystron. 3) Attempt to couple modulated LH waveform at 90 deg phasing, 40 kV, 80 kW/klystron. If successful increase power to 110 kW/klystron, then 140 kW/klystron at 90 deg phasing. 4) Repeat 3 at 146 deg phasing.

Continuation of MP 468 (LH Modulation) Second 1/2 of run day 1) Start with 500 kA, nl04=5e19 (1070827007) Modulate 146 deg phasing LH 12.5 ms on, 12.5 ms off from 0.5 to 1.2 s Try to get 4-5 clean shots at this condition 2) Increase current to 1000 kA, nl04=5e19 Modulate 146 deg phasing LH 12.5 ms on, 12.5 ms off from 0.5 to 1.2 s Try to get 4-5 clean shots at this condition 3) If there is time, move to 800 kA, nl04=7.5e19 (1070426013) Modulate 146 deg phasing LH 12.5 ms on, 12.5 ms off from 0.5 to 1.2 s Try to get 5 clean shots at these conditions. Runplan subject to change, depending on how conditioning run goes in the morning. May need to reduce n_|| to 2.9.

Summary: Continuation of MP 468 (LH Modulation) Second 1/2 of run day The conditioning run in the morning was semi-successful and produced the proper waveform into a higher density plasma for lower phasing than desired. Given the results of the conditioning run, I decided to try to get condition #3 from the session leader plan, the only condition at high density. We were repeatedly unable to get the desired modulated wave form for 146 degree phasing (n_||=3.1), so we decided to move on to 135 degree phasing instead. Even at the lower phasing, there were many LH nuissance trips. As before, LH was tripping frequently during the fall in power. We did get 5 shots at 135 degree phasing with between 5 and 20 complete modulations and 7 shots at 146 degree phasing with between 3 and 6 complete modulations.

Machine ran fairly well today, with a few minor problems.The programmed shot was a nominal 800 kA, 5.4 T, nelo4 ~ 5-7e19 m-2 discharge. The objective was to try to get fast electron transport data at high phasing corresponding to n_par ~ 3.1. The problem has been (and continues to be) fairly high reflection coefficient at this relatively high value of n_par. During much of the day,various densities, outer gaps and RXL programs were tried in order to minimize the reflection coefficient. Nevertheless, the best values obtained were still high, ~ 40%. The first plasma attempt failed due to lack of commutation.Thereafter, most of the shots ran full length, with the exception of a few that suffered early disruptions and one in which the OH2 crowbarred. The ICRF piggybacked up until shot 25 in order to prepare it for tomorrow's run. Scorecard: 31 plasma attempts, 1 failed commutation, 1 OH2 crowbar, 3 disruptions, 1 fizzle and 25 full length plasmas

Session Leader Comments
Aug 12 2010 09:29:01:143AM	1100812002	Greg Wallace	80kW/klystron, 146 deg phasing. Many trips, possibly caused by ICRF running during LH pulse. Will retry for next shot without ICRF.
Aug 12 2010 09:53:19:313AM	1100812003	Greg Wallace	Clean LH pulse at 146 deg and 80 kW/klystron. JGDC signals were unintentionally masked, should have tripped substantially. Reflections on col 2 and 12 JGDC were over 60%. Klystron 1 phase is off by 10 deg. Will try adjusting that to see if reflections on col 2 go down.
Aug 12 2010 10:07:24:263AM	1100812004	Greg Wallace	All trips at 146 deg, 80 kW. High reflections (>60%) on col 2, 12, 14. Will increase trip level to 80% on those columns. Next shot will repeat with slightly lower density. No LH Langmuir probe data again. Roman thinks this is related to his problem with other probes.
Aug 12 2010 10:23:37:373AM	1100812005	Greg Wallace	80kW/klystron, 146 deg phasing. More trips, this time from col 7 and 10, but some sustained periods at full power. Will move launcher to 0.1mm behind limiter on next shot. LH Langmuir probe data is back but looks a little flakey. Density down a little bit (nl04~8.5e19).
Aug 12 2010 10:39:34:620AM	1100812006	Greg Wallace	Many trips again at 80 kW/klystron and 146 deg phasing. Will try decreasing outer gap for next shot by 8mm.
Aug 12 2010 10:53:57:600AM	1100812007	Greg Wallace	Better during first half of LH pulse, but still all trips during the second half. 80 kW/klystron, 146 deg. Went into cell to put attenuators on klystron 4 and 7 RINTs. Will repeat same plasma and setpoints.
Aug 12 2010 10:57:58:480AM	1100812008	Greg Wallace	Fizzle.
Aug 12 2010 11:19:33:600AM	1100812009	Greg Wallace	Only 1 trip at 80 kW/klystron 146 deg phasing with added attenuators on klystron 4 and 7 RINTs. Next shot will attempt modified modulation waveform at 90 deg phasing, 80 kW/klystron during odd segments, 10 kW/klystron during even segments. Still only 10 segments during LH shot (slow modulation).
Aug 12 2010 11:34:57:997AM	1100812009	Greg Wallace	Good shot at 90 deg phasing 80 kW/klystron and slow modulation (50 ms modulation pulses). Next shot will try 12.5ms modulation pulses.
Aug 12 2010 11:46:05:913AM	1100812011	Greg Wallace	Good shot! No trips with full modulation waveform at 90 deg, 80 kW/klystron. Will move on to 125 deg phasing with modulation waveform.
Aug 12 2010 12:08:56:280PM	1100812012	Greg Wallace	Many trips on col 12 JGDC. 80 kW/klystron, 125 deg phasing. Will add attenuator to col 12 JGDC reflected diode.
Aug 12 2010 12:13:51:740PM	1100812012	Greg Wallace	Many trips on col 12 JGDC. 80 kW/klystron, 125 deg phasing. Will add attenuator to col 12 JGDC reflected diode and try again.
Aug 12 2010 12:38:58:163PM	1100812013	Greg Wallace	Three trips. First one looks like FINT05 power jumped before others, therefore causing the trip. Might want to have masking between segments. Next shot will try again with timing of LH moved to accomodate more ICRF conditioning.
Aug 12 2010 12:43:59:613PM	1100812014	Greg Wallace	A few trips later in the shot. Will decrease nl04 to 6e19 and increase phasing to 146 deg.
Aug 12 2010 01:07:56:250PM	1100812015	Greg Wallace	Many trips at 146 deg 80 kW/klystron. Will try to repeat for the next shot to see if problem gets better. If performance does not improve we will swap 1dB attens for 2dB attens on klystrons 4 and 7.
Aug 12 2010 01:37:45:173PM	1100812017	Greg Wallace	Ran clean for first half of shot, then many trips at 146 deg, 80 kW/klystron. Will go to 100 kW/klystron and increase trip levels on cols 2, 3, 14, 15.
Aug 12 2010 02:16:47:500PM	1100812019	Greg Wallace	More trips again?!?!? Increasing trip levels some more at 100kW/klystron, 146 deg phasing. Tired of playing whack-a-mole... Increasing power during "off" to 15 kW.
Aug 12 2010 02:30:26:697PM	1100812020	Greg Wallace	All trips. Will decrease outer gap by 5mm to see if some additional density at the grill improves the coupling.
Aug 12 2010 02:45:32:603PM	1100812021	Greg Wallace	A little better when the density is higher at beginning and end of LH pulse. Giving up on trying to get 146 deg phasing at lower density for Andrea. Signing out as SL and giving over the run to Andrea at this point. Next shot will have 120 kW/klystron at 146 deg with nl04 set to 7.5e19.
Aug 12 2010 03:04:17:387PM	1100812022	Andrea Schmidt	LH doesn't seem to be behaving at low density, so we're starting with condition 3. Stepped up the power for this shot and raised the density slightly. Only a few pulses ran cleanly. Next shot will go back to shot 14 plasma from earlier in the day and lower phasing to 135 degrees.
Aug 12 2010 03:13:51:197PM	1100812023	Andrea Schmidt	Pretty clean shot. All trips during the low power portion of the modulation. We are having trouble keeping the density constant. For the next shot, we will move the LH to start at 0.9 s for better density control. (ICRF will be off)
Aug 12 2010 03:19:46:417PM	1100812024	Andrea Schmidt	Disruption. Try again.
Aug 12 2010 03:47:48:383PM	1100812025	Andrea Schmidt	Many trips. Recently discovered that the x-point was being swept in this shot. Next shot will have more constant magnetic profile.
Aug 12 2010 03:54:47:363PM	1100812026	Andrea Schmidt	No plasma. Try again.
Aug 12 2010 04:26:58:110PM	1100812027	Andrea Schmidt	Got 5 clean pulses, then trips. Try again.
Aug 12 2010 04:38:38:427PM	1100812028	Andrea Schmidt	Got 9 clean pulses (not consecutive). Try again.
Aug 12 2010 04:40:43:580PM	1100812029	Andrea Schmidt	No plasma. Try again.
Aug 12 2010 05:08:09:337PM	1100812030	Andrea Schmidt	9 clean pulses. try again
Aug 12 2010 05:09:07:037PM	1100812031	Andrea Schmidt	11 clean pulses. end of run.

Physics Operator Comments
Aug 12 2010 09:04:52:557AM	1100812001	Ron Parker	Loaded shot 1100804001, with fill gas pulse stretched to 50 ms since cryo will be on for first shot.
Aug 12 2010 09:17:56:000AM	1100812001	Ron Parker	First shot was a dud, probably too little fill gas. Ooops, this was not the problem -- instead a failed commutation. Next: Increase fill gas pulse to 55 ms.
Aug 12 2010 09:37:42:987AM	1100812002	Ron Parker	Shot 2 started up well, but disrupted at 1.4 s probably due to ICRF belching. ICRF was on early, even though it was not supposed to be. Next: repeat, but ICRF off until 1.2 s (hopefully)

Aug 12 2010 12:47:49:467PM	1100812014	Ron Parker	Shot full 14 ran full length. Flattop extends to 150 ms. For next shot, density will be lowered to nl04 = 6e19.
Aug 12 2010 12:57:41:270PM	1100812015	Ron Parker	Shot 15 ran full length.
Aug 12 2010 01:14:20:223PM	1100812016	Ron Parker	Shot 16 ran full length. 146 deg phasing still a bit problematic

Aug 12 2010 03:20:13:013PM	1100812023	Ron Parker	Shot 23 ran full length, but density is not well controlled until ~ 1s. for next shot, turn ICRF off and move LH to start at 0.9 s and end at 1.4s.
Aug 12 2010 03:35:25:183PM	1100812024	Ron Parker	Disruption -- OH2 crowbarred. Check fuses in pwr room. Fuses OK, next shot coming up
