MP 355C ICRF testing and conditioning, with detection of mode conversion location Purpose of experiments: Conditioning the ICRF system (D+E antennas), and also measure the location of RF mode conversion in H/D plasmas with large H/D ratio (compare the H/D level from H_alpha measurement and that from PCI measurement) Plan: 1. Start with Bt0 = 6.0 T, 800 kA, nl = 0.8e20 m^-2, LSN plasma. D antenna: 1 MW, 0.5-0.9 sec E antenna: 1 MW, 1.0-1.4 sec. 2. Adjust Bt0 field based on the observed H/(H+D) level and PCI data. Adjust D and E antenna powers for conditioning the antennas. 3. Possibly program a B field ramp in order to clearly see the MC location. 4. H/(H+D) level is expected to rise shot by shot. Try to have two shots with reasonably clean RF pulses at each H/D level.

SL_summary: 1. conditioned D and E antennas to 1.5 MW, running separately. 2. Run the new J antenna up to 1 MW. No problems encountered. Also tried mono-pole phase in the last a few shots. 3. Recorded H/(H+D) level and compared with PCI inferred H/ne data, for the range of H/(H+D) of roughly 15% to 35%. 4. H/(H+D) rises shot by shot. 5. Nearly no heating effect observed at this H level.

Physics Operator Summary for Tuesday, 6-Dec-2011 MP#355c ICRF conditioning with MC location measurements SL: Yijun Lin PO: wolfe EO: Pfeiffer, Dekow A relatively successful run. RF made progress on conditioning D&E up to ~1.5MW, and also got J going up to 1MW level, limited by voltage handling of N2 in the transmission lines. We started at 6.0T so PCI could see the mode conversion layer, and then moved up to 6.2 as the H/(H+D) level rose with more RF power. This seemed to be successful, with Naoto reporting nH/ne fractions close to Earl's H/(H+D) signals. At shot#13 we went back to 5.4T for the rest of the run. The machine ran fine at 6 and 6.2T, with somewhat slower cooling rates. Since the coax resistances have been good and we were double swinging anyway, I had Andy move the Fizz Gate Off time from 2.1 to 1.8sec for shot#12 to get rid of the TF increase and long pulse, but then we went back to 5.4T anyway. The sparker was misbehaving all day, with current dropping from the usual .2mA to around .1 mA or less. Jim Irby posted a logbook entry noting that it appeared to be voltage limited, and suggesting Bill Parkin could increase the supply voltage. However, the lower current did not appear to be adversely affecting breakdown. The sparker appears to be bistable, with two current levels. Operation was pretty reliable, at least up until a hard disruption (RF induced) on shot#25. After that we had three fizzles in a row, one plasma, another fizzle, then four more plasmas with somewhat shaky startups. Runaways were not a problem today; we had a few shots with ~3e13 levels on neuts/hards with a little snow on the tv, but nothing serious. I did a fair bit of fiddling with the startup, mostly gas, some voltage and rcur tweaks, to no obvious benefit. On the last shot I did try dropping the plateau voltage in the seg1 pg3 puff, which had already been shortened a lot from what we used last year. This actually seemed to help with a hesitation and inward drift that had been present for the last part of the run. Might be worth leaving at the lower (30V) level just to see how it behaves for extended periods. There was one power system problem: oh2l crowbarred at switch close time on shot #23. No blown fuses were found and the next shot ran fine. There was a logbook problem, maybe more than one, at the beginning of the day. Initially the web-based logbook wouldn't come up for me, and people with browsers already up reported slow response. IDL entry_display was working for me. Then around shot#4 we started getting the error message indicating unable to allocate space. Josh and Tom fixed this by around shot#7, by changing a database parameter. It then took a few more shots before the logbook could be convinced to advance the current shot number. Everything seemed to work from around shot#10 to the end of the day. Then I had a brief hang trying to make the physop entry for the last shot (running in Chrome), but it eventually made it. I don't know if this means the problems aren't completely fixed or maybe there was just a network issue at the time. Scorecard: ---------- Gas tests/No Power 2 Duds 1 (power supply fault) Fizzles 7 Plasmas 24 (all but one full length) =========== == Shots 34

Dec 6 2011 08:45:36:720AM	1111206001	Steve Wolfe	Shot#1: Gas and data cycle test Expect B-main not to respond with short progammed pulse, but we'll see. Now making logbook entries in chrome. Result: Btop responded, B-main did not. Will program a longer high level and retest before run RF will be turning on FMIT# 3 and 4 for vac testing
Dec 6 2011 09:10:22:460AM	1111206002	Steve Wolfe	Shot#2: Gas and data cycle test Program pg3 to 100V from -.019 to +.004 to exercise valve Load at 6-Dec-2011 08:48:59.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done Waiting for RF guys to finish with FMIT#3,4 setup. Note that Sparker was working and arcing on the gas test shot#1, but it looks like there was a loss of current between -0.5 and -0.25sec; have to keep an eye on that. Voltage over 20kV Result: Got gas that time B-main responded fine. Sparker is below 0.06mA for an extended period before t=0, just recovers at -0.07 sec; this could be trouble. Next: Reprogram pg3 in seg1 and go for plasma, hope sparker cleans up.
Dec 6 2011 10:44:56:260AM	1111206004	Steve Wolfe	Logbook is hosed again, can't make entries Tried from chrome and from idl, error both times Keep log in emacs until Tom fixes it: Shot#4: repeat after long delay to track down issue with E-port; seems to have been a bad point in the programmed waveform, but Yijun is still not sure how it did what it did. Result: plasma full length some early runaways some hestitation in initial current rise, just over 200kA at 50msec Sparker still faulting, maybe better than last time; cleaning up? Voltage down to 18kV around t=0 this time. D&E still ratty, no early pulse from E this time. Some evidence of heating on Te trace during Eport faulting Density feedback puff is putting in about 10Torr-l H/D going from .22 to .3 this time Next: No DPCS changes
Dec 6 2011 10:43:42:420AM	1111206005	Steve Wolfe	Shot#5: no dpcs changes Plasma full length, xraus at 3e13 level, current rise getting slower, starting to move in. Next: Decrease PG4 from 17 to 16msec Load at 6-Dec-2011 10:12:22.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done Logbook still not taking entries from me. Tom claims he could enter a one-line, but I don't see it.
Dec 6 2011 10:39:44:047AM	1111206006	Steve Wolfe	Shot#6: Decrease PG4 from 17 to 16msec Yijun managed to get a logbook entry after several tries for shot#5. Result: Fizzle, big C signal, looks like it's moving in. EF4 is already at -1310. Sparker was down at t=0 on this one, but the breakdown time was normal. Complicating things is that Wukie is pulsing J into vacuum between shots; no obvious junk on RGA. Next: Reduce PG4 from 16 to 15msec Load at 6-Dec-2011 10:28:49.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done
Dec 6 2011 10:42:48:073AM	1111206007	Steve Wolfe	Shot#7: Logbook is sort of fixed, but didn't have a shot record for shot#7. Shot#7: Reduce PG4 from 16 to 15msec Result: plasma full length, early CIII signal still large and spiky, RCUR indicates early move in, then out, xrays down to 2e12 Sparker is down to 0.1mA until after t=0; I think it's dead or dying D still faulting, E better. Next: Repeat
Dec 6 2011 10:54:17:890AM	1111206008	Steve Wolfe	Shot#8: No dpcs changes, though I'm tempted to drop the RCUR offset to 2500. Result: plasma full length. current rise a little worse logbook is not advancing shot number Next: raise B to 6.2T
Dec 6 2011 11:14:27:747AM	1111206009	Steve Wolfe	Shot#9: raise B to 6.2T (174.1kA), current limit to 180 reduce rcur offset from 3500 to 2500 in seg1 Load at 6-Dec-2011 10:57:45.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done ALternator is reducing speed because they are close to alarm state on #2 bearing IGT at INIT =1.9e-6 Result: plasma full length Sparker came back up briefly before t=0, then back down. I don't know if it's doing any good at the 120uA level or not. Current rise still slow, small inward motion before 20msec D and E cleaning up ?? J trying in between them, with not much success. B=6.18T Next: No dpcs changes
Dec 6 2011 11:30:11:110AM	1111206010	Steve Wolfe	Shot#10: No dpcs changes Josh is still trying to get the logbook to notice the current shot change IGT at INIT=2.3e-6 Result: plasma full length, a few early hards (3e13) possible bounce(?) just after 10msec, but then moving in. Logbook current shot advanced to 10 D&E looking better, J just looking Sparker still at 0.11mA until t=0, except briefly at .21 around -1sec Supply Voltage claims to have gone to 35kA after +17msec on fast trace! I didn't think it was set that high??? Must be a subtraction error, that trace is calculated in the scope Next: No dpcs changes
Dec 6 2011 11:48:30:260AM	1111206011	Steve Wolfe	Shot#11: No dpcs changes We're having slow cooling, I think I'll move the fd gate earlier so we don't extend the tf pulse on full plasmas. Coax resistances look fine. Result: plasma full length current rise a little faster, no runaways H/D (marmar) around 0.5 after 1 sec Jport ran together at .15MW each D and E still hanging in around 1MW (separately) Sparker still looks bad, less than 0.1mA before t=0. Next: Asked EO to move fd off from 2.1 to 1.8sec No DPCS changes
Dec 6 2011 11:58:37:027AM	1111206012	Steve Wolfe	Shot#12: No dpcs changes, fd off gate to 1.8sec Did a load just to get a new title (6.2T) on seg2 IGT at INIT=2.2e-6 Result: plasma full length current rise looks ok, no runaways Sparker got to 0.2mA before t=0, then dropped back E ran clean over 1MW, J looking pretty good up to 0.5MW D still hashy Next: back to 5.4T

D just under 1MW, some faulting, then J at .35each, then E up to 1MW, then J again in rampdown B=5.4T as requested Next: repeat
Dec 6 2011 12:31:37:090PM	1111206014	Steve Wolfe	Shot#14: no DPCS changes IGT at INIT=2.5e-6 (13min in recool) Irby has indicated that the sparker may need to have its voltage raised, but the low level could be ok (see logbook entry under Ops). I'll leave it for now, since the plasmas seem ok with it. Result: plasma full length, current rise slower, under 150kA at .05sec Sparker is back up to 0.22mA for most of its pulse this time. RF trying to stack, with mixed success, max power up to 2MW, no noticeable heating. 2pi foil is up to 1.5MW. H/D was over 0.5 Next: No DPCS changes, RF continuing to bang away
Dec 6 2011 12:41:21:190PM	1111206015	Steve Wolfe	Shot#15: no DPCS changes IGT in INIT=2.6e-6 Result: fizzle looks like a bounce, or a couple of bounces. Sparker back down to .8mA until just before t=0, then pops back up Next: raise pg4
Dec 6 2011 12:57:34:697PM	1111206016	Steve Wolfe	Shot#16: raise pg4 from 15 to 17msec Load at 6-Dec-2011 12:42:20.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done Result: plasma full length, some early runaways ~5e13 still a possible bounce around 11msec close to 200kA at .05sec D faults out early, E almost clean for length of flattop J ok from 1 to 1.2sec, .7MW total, then faulting. Sparker was back down to 70uA for most of pulse this time. Next: rcur offset to 3000 in seg1
Dec 6 2011 01:09:27:087PM	1111206017	Steve Wolfe	Shot#17: rcur offset from 2500 to 3000 in seg1 Load at 6-Dec-2011 12:56:12.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done Note that the monitor has been reporting over 0.6% changes in ef2L the last two shots. Not sure why. The ef2 scope shows no signal from the D supply, but it's been like that IGT at INIT=2.4e-6 Result: plasma full length, no runaways No apparent bounce this time. D still some faults, E pretty clean at 1.1MW, J clean at 0.6MW (total) Next: repeat
Dec 6 2011 01:26:50:803PM	1111206018	Steve Wolfe	Shot#18: repeat, no DPCS changes IGT at INIT=2.2e-6 (over 15 min in RECOOL due to cell access for DNB) Result: plasma full length, current rise the same as 17, no runaways RF looking cleaner on this shot, E up to 1.2MW almost clean Next: repeat
Dec 6 2011 01:44:55:120PM	1111206019	Steve Wolfe	Shot#19: repeat, no DPCS changes IGT at INIT=2.9e-6 may be pushing it, 2.5e-6 going to pulse Result: plasma full length, about 150kA at .05sec, no runaways inward motion a little further before 17msec, CIII signal up around 11msec E is up to 1.3MW, one fault, D clean around 1MW, J a couple faults on the rise to 1.1MW, then clean. Next: No DPCS changes, Amanda is going to change the ECE grating for 5.4T
Dec 6 2011 01:53:33:063PM	1111206020	Steve Wolfe	Shot#20: repeat, no DPCS changes IGT at INIT=3.0e-6 Result: plasma full length, no runaways, similar current rise maybe a little further inside C light back down D up to 1.3MW, E to 1.5MW, J at 1.1MW in between Next: repeat
Dec 6 2011 02:04:27:490PM	1111206021	Steve Wolfe	Shot#21: repeat, no DPCS changes IGT at INIT=2.8e-6 Result: fizzle, oh well! C light shows some spikes, might have bounced, but rcur seems to be moving in Next: Drop pg4 by 1msec
Dec 6 2011 02:18:22:670PM	1111206022	Steve Wolfe	Shot#22: Drop pg4 by From 17 to 16msec, just to do something Load at 6-Dec-2011 14:05:41.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done IGT at INIT=1.9e-6 Result: plasma full length, some early runaways, looks like a bounce at 11msec. I'm going to leave it alone and see if the increased gas load after a plasma calms it down. All RF's ran clean, between 1 and 1.2MW, D-J-E. Next: repeat
Dec 6 2011 02:32:50:167PM	1111206023	Steve Wolfe	Shot#23: repeat, no DPCS changes Result: Dud - PF breaker pulled out near -0.6sec OH2L crowbarred first, around -0.7sec, near switch close time. OH coax warning seems to be bogus due to low currents Next: Engineers checking power systems
Dec 6 2011 02:59:53:620PM	1111206024	Steve Wolfe	Shot#24: repeat, no DPCS changes Result: plasma full length, no runaways Got D and E, but J faulted out. Next: repeat
Dec 6 2011 03:14:23:033PM	1111206025	Steve Wolfe	Shot#25: repeat, no DPCS changes IGT=2.3e-6 at CHECK Result: plasma disrupted at 1.34sec, during RF (Dport) J ran, then had faults, E had a couple of faults at 1.1MW That one evolved a lot of gas, MKS claims over 100Torr-l with 11 injected. Next: reduce pg4 post-disruption
Dec 6 2011 03:23:45:563PM	1111206026	Steve Wolfe	Shot#26: reduce pg4 from 16 to 14msec Load at 6-Dec-2011 15:15:23.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done IGT at INIT=3.3e-6, may as well just go for it Result: fizzle. What a surprise! Next: just repeat, recovery may take a while
Dec 6 2011 03:38:08:317PM	1111206027	Steve Wolfe	Shot#27: just repeat with pg4 at 14msec, recovery may take a while IGT at INIT=1.9e-6, maybe this will work Result: Nope, another fizzle. C light a lot brighter this time, maybe a hint of current, Z-meter still lumpy. Next: drop pg4 by one more msec
Dec 6 2011 03:51:41:460PM	1111206028	Steve Wolfe	Shot#28: drop pg4 from 14 to 13msec Load at 6-Dec-2011 15:39:02.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done Result: Fizzle again! Still lots of C light, hardly any current I'd ecdc but we only have about an hour left anyway. RGA is showing lots of 16 slowly coming down since the disruption, 28 is mostly back to pre-shot#25 levels. It ought to be ready to go. Next: Drop Seg1 rcur offset back to 2500, pg4 a little bit more
Dec 6 2011 04:06:01:230PM	1111206029	Steve Wolfe	Shot#29: drop pg4 from 13 to 12msec rcur offset from 3000 to 2500 Load at 6-Dec-2011 15:52:49.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done If it runs I'll need to start undoing some of that If not, just keep banging away? Result: plasma full length, finally. And no runaways current rise is slow, about 120kA at .05sec and it still moved in, but made it. The walls pumped a little bit on this one, 6Torr-l out with 16 T-l in. C light only down a little, around 0.02 J ran with multiple faults, then steady for a short while E and D ran clean, all around 1MW. Next: leave short prepuff until it starts giving runaways
Dec 6 2011 04:18:52:503PM	1111206030	Steve Wolfe	Shot#30: no dpcs changes this time, see if it starts bouncing. Result: fizzle, which way did it go? rcur seems to be moving in, but there are tiny spikes on C and Halpha around 15msec, can't tell anything from bounce scope. Next: Rcur offset back to 3000 in seg1
Dec 6 2011 04:37:26:257PM	1111206031	Steve Wolfe	Shot#31: Rcur offset from 2500 to 3000 in seg1 PG4 from 12 to 13 msec Load at 6-Dec-2011 16:20:06.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done Result: plasma full length, no runaways, still moving in, slight hesitation between 10-18msec, C light lumpy, Zmeter burns out, then rises a bit. Startup looks iffy. RF runs just over 1MW with a few faults: order J/E/D Divertor energy didn't update on 31, had a reading on inner divertor on 30 (which had no plasma); possible problem. Next: repeat, cross fingers
Dec 6 2011 04:40:10:107PM	1111206032	Steve Wolfe	Shot#32: Changed my mind: Reduce EF3_VOLT point at .012 sec from 2800 to 2600 see if that's responsible for the inward motion after 10msec Load at 6-Dec-2011 16:33:01.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done Result: plasma full length, some early runaways. inward motion is worse, if anything, no obvious benefit to decreasing ef3, so put it back next time. RF ran in same order, stepped up power on D&E Next: put back EF3_VOLT
Dec 6 2011 04:55:56:183PM	1111206033	Steve Wolfe	Shot#33: put back EF3_VOLT point at .012sec from 2600 to 2800 Load at 6-Dec-2011 16:41:14.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done RF is playing with the phasing on J this time IGT=2.9e-6 at INIT Result: plasma full length, no runaways, but it almost didn't make it, hesitation and slight back-off in current at 13msec J had a couple faults, maybe related to monopole phase? E and D also had faults, E worse than D, both around 1.5MW Next: Reduce pg3 at t=0 a little
Dec 6 2011 05:10:49:890PM	1111206034	Steve Wolfe	Shot#34: Reduce pg3 at t=-1msec and after from 40 to 30V; may not do much, since this is on the software chopper. Load at 6-Dec-2011 16:57:08.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done Result: plasma full length, smoother current rise, less inward motion; I think maybe the lower pg3 puff helped, maybe J stayed on with monopole phasing in the middle of the pulse. 2pi diode drops like a stone during that period, I don't think it's believable, but it notices. Foil goes berserk, bipolar. Probably rectifying? D and E also clean at 1.4MW or so. END OF RUN
