MP 633 Lower Hybrid Rotation Scans in Different Magnetic Geometries SL Y. Podpaly PO S. Wolfe The goal of this run is to help understand the co versus counter current rotation observed from LHCD. Tentative Run plan (subject to change as rotation is observed) 1- Locked mode calibration for HiReX Sr (Ref. Shot = 1110125003). 2- USN Rotation Studies (Ref. Shot = 1101119008) Set nl04 ~4E19, PLH = 800 kW, Bt = 5.4, n||=1.6 a. Start at 800 kA and drop current (in 100 kA increments) on progressive shots to 300 kA. Identify the zero rotation change point if possible. Locked modes may require retakes of these shots. 3- Repeat Locked Mode Discharge (Ref. Shot = 1110125003) 4- LSN Rotation Studies (Ref. Shot 1101028006) set nl04~4E19, PLH = 800 kW, Bt = 5.4, n||=1.6 a. Repeat 2a in LSN geometry. Start at 800 kA and drop current (100 kA increments) until cannot go lower or no LHCD rotation change. 5- Understanding Collisionality/LH effect on Rotation. USN (Ref. Shot = 1101119008) a. Power Scan: Ip~400kA PLH scan at 600 and 1000 kW. b. Density scan: nl04 =3E19 to nl04 = 8E19 with current and power to be determined by previous scans. c. n|| scan: n|| =1.9, 2.1, 2.3 d. Magnetic Field: Bt = 6.2 T and 4.6 T 6- Repeat part 5 at 700 kA for collisionality/LH scan completion LH Launcher position with respect to the limiters: (Whatever it was on shots 1101019014 and 1101028006) mm LH Start time: 0.8 sec LH Stop time: 1.3 sec Phasing: 75 deg Mostly at n||=1.6 but some variation possible Net Power desired: Between 600 kW and 1000 kW LH Run Duration: Full day Waveform description: Either: Standard: Box (with ramp) Or, unlikely but may be requested, Special: Standard box but modulated with 100 kW (or higher as needed) at 10 Hz. (e.g. at 800 kW it would be 850 KW for 100 ms, 750 for 100 ms, 850 for 100 ms, etc.)

Load seg 1 and 2 from 1101119008, low current startup, 400kA. SL has decided not to start with locked mode calibration shot from 1110125003, seg 4, so just load this in segment 4, modify the first current point so we can use the 1101119008 startup, and turn it off. 1 USN target from 1101119008, seg 2. Change Seg1 EF4 from -1300 to -1290, modify pg4, pg3 to taste. Seg2: Change nl04 target from 2.9e19 to 4e19 Increase Ip from 400kA to 800 kA. Note this shot used a "low current startup", Ip gain is on in seg1, better check what else it's doing. OH crowbars are at 0.07sec, EF1's still at .2sec. It still overshot the 400kA a bit, so I can tweak on it a litte, but we're going to start the current scan at 800kA and work back down to 300kA, so just make sure the 0.1sec point is consistent to start. May want to lower OH voltage in seg2 as we drop Ip. 2. Run lm calibration shot from seg4. May just reload the whole thing, in which case I have to remember to tell the EO to load the engineering setup so I don't get the early crowbar time. 3. Import LSN target 1101028006, seg2. This is a 550kA case with a normal startup, but I can use the low current seg1 since we're again going to be scanning down. Initially set nl04 from 2.5e19 to 4e19 and raise Ip from 550 to 800kA. Scan down in Ip to 300kA in 100kA increments. 4. Back to USN case, 400kA. a) Do an LH power scan: 600kW, 1MW b) scan nl04 from 3e19 to 8e19, current and power tbd c) N|| scan (3 points) d) TF to 6.2T (172kA, remember to raise PLC limit) TF to 4.6T (128kA) 5. Repeat part 5 at 700kA

Despite the many disruptions, duds, and fizzles that plagued this run, we got some very good data. The USN section of the experiment was completed and the dv versus ip scaling was confirmed. Also the zero rotation change point (~550 kA) was identified at nl04~4E19 and PLH 800 kW. Interestingly, above the zero rotation point in Ip, the scaling of rotation with Ip appears to be completely different. All of 700 kA, 800 kA, and 900 kA discharges had very similar rotation behaviors. An interesting observation from this run was that almost all of the final rotation magnitudes at the end of the 0.5 s LH pulse were identically -20 km/s. The LSN scan was also successful. We discovered that the LHCD can go in the co-current direction. The reversal point (~400 kA) however is significantly lower in current than the USN case. For higher currents, the delta in rotation is effectively unchanged by the plasma current, but for lower currents we recover the seeming Ip scaling. It was also possible to piggyback intrinsic rotation scaling with Ip by the pre-LHCD sections of the discharges. Overall, it seems like there is a sharp bifurcation in the rotation in both LSN and USN, but at different currents. The location of the bifurcation in DN would be interesting to observe but will have to be left for later. We were not able to do the collisionality scans, but since the Te, Ti, and ne were comparable in the USN cases for both co- and counter-rotation this effect is looking less likely; the density however may still be a culprit in the problem. There is a possible suggestion that the reversed n|| launched from the LH launcher may explain the difference since that spectrum is lost in the scrape-off layer. Running at different n|| in the future will be needed to test this.

Physop summary for Friday, Jan 28, 2011 MP#633 Lower hybrid rotation effects SL: Podpaly PO: wolfe EO: Tesfaye, Fitzgerald, Byford A long day, but a lot was accomplished. We completed the two major current scans, one in USN and one in LSN, and found rotation reversal points with LHCD in both configurations. We also got a locked mode calibration shot (step 2). Steps 4 and 5 of the SL_PLAN were not attempted. The initial plan of using the low current, early OH crowbar startup from 1101119008 for the 800kA discharges was not successful. After two early disruptions we put the crowbar back to .120sec and reloaded a standard startup from Wednesday, and put the initial Ip point in seg2 back where it had been. This got decent discharges, and we used the normal startup for the rest of the day, allowing overshoots and rampdowns in the active segment for the low current cases. Gas puffing and increased early density program were implemented to avoid locked modes. This was mainly successful. The following density control settings were implemented as of shot#9 and used for the remainder of the USN scan and most of the LSN scan, with a minor adjustment for the lowest currents of LSN: for NL04 : P=4, D=6, I=1 (Int gain after 0.6sec) for PG3: Start at 50V from .1 to .2sec, down to maintenance level of 20V to EOF The same prescription was used for the LSN, resulting in slightly higher density before and during LH, but still acceptable, until shot#30 at 300kA, which had a monster early marfe, followed by a locked mode. The locked mode at very low current seemed unusual, and was undoubtedly (?) associated with the marfe, which also led to _lower_ density in flattop. I then reduced the PG3 feedforward from 50 to 35V, which seemed to cure the marfe and locking, and gave good density traces, though still increased during LH. On shot#18 I started using Integral gain on the current to get better control during the LHCD and also more consistent behavior on fine adjustments with targets near 500kA. The final settings, used from then on, were: P=9 from 0.5sec (moved from 0.65) and I=4 from 0.55sec, D=0. This seemed to work well, although an even higher gain might have been able to reduce the overshoot during LHCD even further; as it was this was less than 10kA after the initial transient. For the lowest current cases, I le 400kA, I dropped the OH1V from .1 to .15sec from 250V to 150V. The seg1 value of 250V was left in place. The LH group reported that the density at the launcher increased dramatically as the current was decreased, and requested variations of the outer gap to compensate. These gap changes, totalling over a cm for the 800 to 300kA current scans, seemed to help the LH coupling and did not have any obvious detrimental effect on the plasma. When we moved on to the LSN current scan (shot#21-34) I extended the flattop to 1.7sec as in the USN cases. These shots all terminated at about 2sec, while many of the USN ones continued to rampdown later than that. I thought I had missed extending some gains, but couldn't find anything. Since we were scanning down in current anyway, I ended up speeding up the rampdown so it ended by the time the plasma was going to disrupt. We had a couple of fizzles, and some early injections leading to runaways. Small changes in the seg1 gas programming, PG4 and PG3, were used to deal with these, with some success. There were also several flattop injections, not all associated with LH, that led to disruptions. There was also one dud, due to failure of TF to come on; it's been a while since that pathology showed up, but it's still out there. We ended up with 24 plasmas past EOF out of 33 attempts. Not a great percentage, but 24 good shots isn't too bad. LH ran well once they got the gaps they needed, and by the end of the day we were able to anticipate the changes fairly well. Scorecard: Tests/No Power shots 0 Duds 1 (no TF) Fizzles 3 Plasmas 30 (6 disruptions in rise or flattop) ============== == Shots 34

Session Leader Comments
Jan 28 2011 09:04:19:610AM	1110128001	Yuri Podpaly	Starting with part 2a at 800 kA and hopefully avoiding the locked mode. Result: Early disruption. Next: Try again.
Jan 28 2011 09:20:08:537AM	1110128002	Yuri Podpaly	Early disruption again. Next: Try again.
Jan 28 2011 09:41:53:130AM	1110128003	Yuri Podpaly	Lower hybrid issues, but we still got a decent 100 ms pulse in early with possible counter current rotation on HiReX Sr, but density also went up so it is hard to say. LH group request change of outer gap for better coupling. Possible locked mode, but HiReX Jr does not see the classic locked mode behavior. Next: Try again with better LH.
Jan 28 2011 10:01:11:810AM	1110128004	Yuri Podpaly	Very clear co-current rotation of +20 km/s. This is not what I expected. Is the locked mode coming in again? HiReX Sr profiles are showing larger than I would like so Ar to 90ms. Thomson shutter was closed on this shot too, so no ne, Te profiles. Next: Continue with current scan to 700 kA
Jan 28 2011 10:00:41:073AM	1110128005	Yuri Podpaly	Fizzle Next: Try again.
Jan 28 2011 10:13:40:897AM	1110128006	Yuri Podpaly	Early disruption again. Next: Try again.
Jan 28 2011 10:37:07:107AM	1110128007	Yuri Podpaly	Locked mode disruption. Unfortunately not good enough for a HiReX calibration, but qualitatively it does not look like it drifted too badly from before. Next: Try again.
Jan 28 2011 10:46:04:357AM	1110128008	Yuri Podpaly	Early disruption during LH. Next: Try yet again.
Jan 28 2011 11:05:31:557AM	1110128009	Yuri Podpaly	Shot went. LH trace good and 20 km/s COUNTER current rotation drive. This is worth exploring later. LH group reports higher reflections so LH power was ~700-750 kW. Next: stick to the plan, 600 kA.
Jan 28 2011 11:07:18:317AM	1110128010	Yuri Podpaly	Dud. No TF. Next: Try again. Wrong kind of chicken.
Jan 28 2011 11:22:20:910AM	1110128011	Yuri Podpaly	This was good. Very slight counter current rotation change. Next: 500 kA. Should rotate co-current if this is right.
Jan 28 2011 11:35:49:350AM	1110128012	Yuri Podpaly	Slight co-current rotation, this is looking more like it. Next: 400 kA
Jan 28 2011 12:03:15:400PM	1110128013	Yuri Podpaly	LH Went. Nice co-current rotation. Next: 300 kA.
Jan 28 2011 12:02:34:593PM	1110128014	Yuri Podpaly	Fizzle. Next: Try again
Jan 28 2011 12:32:28:530PM	1110128015	Yuri Podpaly	Nice co-current rotation trace. Done with coarse scan part. Next: 568kA
Jan 28 2011 12:32:43:473PM	1110128016	Yuri Podpaly	Early Disruption. Next: Try again.
Jan 28 2011 12:46:09:807PM	1110128017	Yuri Podpaly	Current was a little high ~600 kA, and it overlayed the previous 600 kA point fairly nicely. Next: 550 kA.
Jan 28 2011 12:59:58:230PM	1110128018	Yuri Podpaly	This was a good albeit confusing shot. Rotation was mostly flat during the LH flat-top but it was evolving prior to the turn on. Next: 800 kA. repeat, hopefully with better density control.
Jan 28 2011 01:17:26:093PM	1110128019	Yuri Podpaly	Counter current rotation. Only -13 km/s which is strangely low. Maybe hit a plateau? Next: 900 kA and then move on I think.
Jan 28 2011 01:35:25:327PM	1110128020	Yuri Podpaly	900 kA, -15 km/s on the rotation. Very interesting, it looks like the ip scaling only really works at co-current rotation. Next: Move on to section 3. LSN at 800 kA with extended flattop and density to match as closely as possible to USN cases.
Jan 28 2011 01:52:53:893PM	1110128021	Yuri Podpaly	LH did not couple. Next: About time for a HiReX Sr calibration locked mode.
Jan 28 2011 02:06:14:640PM	1110128022	Yuri Podpaly	Successful locked mode calibration for HiReX Sr. Next: 800 kA LSN LH shot repeated.
Jan 28 2011 02:21:41:337PM	1110128023	Yuri Podpaly	Fizzle. Next: Try again.
Jan 28 2011 02:36:48:190PM	1110128024	Yuri Podpaly	Shot went. No LH. Next: Try again, but with LH.
Jan 28 2011 02:52:07:447PM	1110128025	Yuri Podpaly	Successful 800 kA shot. -20 km/s observed. Next: 700 kA.
Jan 28 2011 03:06:08:673PM	1110128026	Yuri Podpaly	700 kA. -13 km/s observed. Noticed that both this and the previous shot reach ~5E19 during the LH pulse. Next: 600 kA.
Jan 28 2011 03:18:35:253PM	1110128027	Yuri Podpaly	Lower Hybrid tripped half-way through. Not good enough rotation behavior to make a judgement. Next: Try again.
Jan 28 2011 03:35:31:530PM	1110128028	Yuri Podpaly	600 kA. Still no change whatsoever in the rotation trace from Ip drop. Density control was worse, may want to revisit this current. Next: 500 kA.
Jan 28 2011 03:51:56:553PM	1110128029	Yuri Podpaly	500 kA; still counter current rotation. Next: In the interest of time, move to 300 kA, skipping 400. We will return to 400 kA if time permits.
Jan 28 2011 04:08:28:260PM	1110128030	Yuri Podpaly	Possible locked mode. Next: Try again.
Jan 28 2011 04:25:36:323PM	1110128031	Yuri Podpaly	Co-current rotation (+25 km/s) in lower single null. As far as I am aware, this is the first time we have seen this in LSN. Next: 400 kA.
Jan 28 2011 04:54:59:823PM	1110128033	Yuri Podpaly	No rotation change for this case. Next: 350 kA.
Jan 28 2011 05:07:36:200PM	1110128034	Yuri Podpaly	Shot went. Lh stayed on and slight co-current rotation. That's all. Thank you.

Jan 27 2011 04:51:52:390PM		Steve Wolfe	Set up the shot for Friday's experiment MP#633: Load from 1101119008 Import seg4 from 1110125003 to seg 4(locked mode calibration shot) Import seg2 from 1101028006 to seg 3(LSN 550kA case) Change OUTPUT_PROS dpcs_piezo_chopper setup OUTPUTS to include "pulse_gas1" In seg1, change IC_EF4U from -1300 to 1290A Reduce PG4 from 70 to 50msec In seg2: title change to USN 800kA Increase flattop of current from 400 to 800kA, note EOF is at 1.7sec Increase nl04 from 2.9e19 to 4.0e19 In seg3: Change title to LSN 800kA Increase flattop Ip from 550 to 800kA, point at 0.1sec to 400kA Increase nl04 from 2.5 to 4.0e19 In seg4: change Ip point at .1sec from 600 to 400ka Save as 1110128000 in ~/pcs_scratch and alcdata-test:/cmod/trees/test/pcs & dpcs
Jan 28 2011 08:06:51:633AM		Steve Wolfe	Setting up for MP#633 on 1110128 Load from 1110128000, saved yesterday Note some details in the programming: Ip has P=D=6 in seg 1, dropping to 4,0 at .1sec in seg2; seg2 has OH1V starting around 250V, which is probably untouched from normal. Could lower this and in seg1 once we start dropping the current. there's a pg3 puff at .2 to .275sec, but it's only 3V, so it's mostly a noop argon puff is only 50msec, which seems low for a HIREX run, but I won't complain until Yuri does. Note that the engineering invert times are 2.2sec for EF1,2,3,4, and CC; 2.5sec for OH's; 3.2sec for TF . OH crowbars are .07sec, EF is .20. FD is .08 to 2.3sec TF current limit is 164ka, need to remember to raise it for 6.2T case, when we get to it. I think this is ready to go.

Jan 28 2011 09:14:04:830AM	1110128001	Steve Wolfe	shot#1: USN based on 1101119008 with higher current and density. Early disruption at .17sec, goes vertically unstable. Seems to be diverting very early. Next: slow down the current rise in seg2 to put BOF at .5sec looks like the OH's were getting slammed and oscillating. Also, delay the jump in zcur to +.009 from .1sec to .2sec
Jan 28 2011 09:21:25:467AM	1110128002	Steve Wolfe	shot#2:slow down the current rise in seg2 to put BOF at .5sec looks like the OH's were getting slammed and oscillating. Also, delay the jump in zcur to +.009 from .1sec to .2sec Early disruption again. Let's move the crowbars back to .12sec, and use a normal startup. Can come back to this later, maybe.
Jan 28 2011 09:36:53:400AM	1110128003	Steve Wolfe	shot#3: Request crowbar times on OH's to move from .07 to .12sec Import seg 1 from 1110126010 (random shot from Wednesday) this has normal t=0 settings, no Ip gain in seg1 Increase Ip prog in seg2 from 400 to 600kA at 0.1sec, BOF at .3sec leave ramp in Zcur between .1 and .2sec to .009 Result: plasma full length (to 2sec), got LH, but it faults after .9sec, lots of runaways after .8sec Might be a locked mode early though. Next: tweak up early density
Jan 28 2011 09:53:17:973AM	1110128004	Steve Wolfe	shot#4: Increase pg3 level in seg1 from 30 to 50V Increase nl04 demand at .1 to .3sec to 5e19, then decrease to 4e19 leave gains at P=8, D=4.5, but consider dropping P next time. Move rcur out by 2.5mm to reduce right gap by 5mm: .656 to .6585 before 1sec, and keep it at .6585 to EOF (was programned to move in to .6545) Result: plasma full length looks like LH stayed on to 1.3sec, then runaways increase to sat level to end of shot. Glad I've got my film badge on! Loop voltage drops to .3V, outer gap is 1.9 and moving in to 1.5cm, not as much change as expected, but seems to work. Next: Decrease Ip to 700kA
Jan 28 2011 10:02:17:667AM	1110128005	Steve Wolfe	shot#5: Decrease Ip to 700kA, second point on current scan#1. decrease Pgain on Nl04 from 8 to 6 to try to improve wobble Increase argon from 75 to 90msec per SL request Result: fizzle, injection at .029sec, followed by runaways. Could be a bounce, or just grazing. Next: increase pg4 from 50 to 55msec
Jan 28 2011 10:16:54:150AM	1110128006	Steve Wolfe	shot#6: Increase pg4 from 50 to 55msec Relative to shot#4: Decrease Ip to 700kA, second point on current scan#1. decrease Pgain on Nl04 from 8 to 6 to try to improve wobble Increase argon from 75 to 90msec per SL request Result: short disruption at .35sec, had runaways early but not a runaway shutdown? Single bouce in startup, but the disruption is either an injection or a locked mode followed by injection. Next: Raise pg4 from 55 to 60, increase pg3 in seg1 from 50 to 60
Jan 28 2011 10:36:07:020AM	1110128007	Steve Wolfe	shot#7: Increase pg4 from 55 to 60msec, pg3 from 50 to 60V decrease Ip program at t=.1sec from 600 to 550kA Relative to shot#4: Decrease Ip to 700kA, second point on current scan#1. decrease Pgain on Nl04 from 8 to 6 to try to improve wobble Increase argon from 75 to 90msec per SL request Result: No bounce this time, and no runaways, but disrupts at .55sec, before LH. This one looks like a locked mode. Need to increase the early density then drop it. Next: increase early program nl04 to 6e19, add pg3 puff in seg2
Jan 28 2011 10:49:26:930AM	1110128008	Steve Wolfe	shot#8: increase early program nl04 to 6e19, add pg3 puff in seg2 to start at 50V through .2sec, dropping to zero at .3sec Still trying for 700kA case. Result: plasma to .95sec, injection during LH, Matt says tungsten. Looks like the locked mode is gone, but the density is not real steady Next: Reduce nl04 P gain to 4, add pg3 maint level at 20V
Jan 28 2011 10:56:42:617AM	1110128009	Steve Wolfe	shot#9: Reduce nl04 P gain to 4, add pg3 maint level at 20V to 1.4sec Still trying to get the 700kA case! Result: plasma full length, marfe early, had an injection at .11 that took a bite out of the current but survived, nl04 reached 7.5, then back down to 4e19 and reasonably steady. LH ok. Could do without the early injection but it's better than it's been. Next: On to 600kA
Jan 28 2011 11:08:00:080AM	1110128010	Steve Wolfe	shot#10: Ip from 700 to 600kA Leave rest of programming alone, and see if the injection goes away on its own. Result: No TF ==> DUD Next: Try that again.
Jan 28 2011 11:21:47:113AM	1110128011	Steve Wolfe	shot#11: Try again at Ip=600kA No pcs changes Result: plasma full length, finally. Still some marfe early, and a few small injections but not serious LH looks good, Vsurf again drops to ~.3V, looks like sawteeth go away during LH ~0.95sec Next: 500kA
Jan 28 2011 11:35:27:300AM	1110128012	Steve Wolfe	shot#12: Ip from 600 to 500kA, keeping 0.1sec point at 550. Add some integral gain I=1 to NL04 and extend pg3 maint level to 1.7sec Reduce RCUR by 1mm (to .6575) to increase gap for LH LH also requested raising ZCUR, but hold off for one shot, per SL request. Result: plasma to 2.1sec,LH stays on ok. Early marfe still present, but maybe smaller. Next: Go on to 400kA.
Jan 28 2011 11:53:27:120AM	1110128013	Steve Wolfe	shot#13: Ip from 500 to 400kA, move gain step in Ip program from .65 to 0.5sec Reduce OH1V at start of seg2 from 250 to 150V, no change in seg1 Leave gaps and ZCUR the same for now. Result: plasma past 2sec, marfe early not too bad, LH stays on ok, some time variation of runaways after LH turn off. Looks like density is varying some during LH. At the end of LH pulse Vsurf is down to .15V Next: 300kA and increase gap another 2mm
Jan 28 2011 12:03:41:533PM	1110128014	Steve Wolfe	shot#14: Ip from 400 to 300kA, increase gap another 2mm (RCUR from .6575 to .6565 Result: fizzle, couple of injections in startup, might bounce at .025sec Thomson needs a pause. Next: PG4 from 60 to 65msec
Jan 28 2011 12:18:13:230PM	1110128015	Steve Wolfe	shot#15: PG4 from 60 to 65msec Relative to 13: Ip from 400 to 300kA, increase gap another 2mm (RCUR from .6575 to .6565) Still working on scan #1 of run plan Result: plasma full length, marfing early and late, and maybe in between Startup was dicey, current rise arrested for awhile around 30msec, but no obvious bounce and no runaways. Current overshoots and comes back down to target ok. Next: Program 568kA (!) and move the rcur back to where it was for shot#12
Jan 28 2011 12:33:14:490PM	1110128016	Steve Wolfe	shot#16: Program 568kA (!) and move the rcur back to where it was for shot#12 RCUR to .6575m OH1V back to 250V in seg2 In seg1, decrease pg3 level from 60 to 50V Result: Short and not sweet. Disrupts at .5sec, before LH. Startup was ok, no runaways. I don't think there's a locked mode, just looks like a brick. Next: Just repeat it
Jan 28 2011 12:45:15:000PM	1110128017	Steve Wolfe	shot#17: Repeat, hoping for no injection Program 568kA (!) and move the rcur back to where it was for shot#12 RCUR to .6575m OH1V back to 250V in seg2 In seg1, decrease pg3 level from 60 to 50V Result: plasma full length, LH looks ok. Current is closer to 600 than 568, maybe I should have put some integral gain on it. Next: Try for 550kA, add some integral gain on Ip
Jan 28 2011 12:58:22:343PM	1110128018	Steve Wolfe	shot#18: Try for 550kA, Turn on Int gain on Ip, I=4 at .55sec Note that if this gain is enough it should reduce the loop voltage during LH. Result: plasma full length, marfe is smaller, LH ok. Ip closer to what was requested, still shows a small increment with LH. Maybe needs more I gain, but this should do for now. Back to 800kA to pick up that point, which had a different density earlier in the day.
Jan 28 2011 01:15:36:033PM	1110128019	Steve Wolfe	shot#19: Program 800kA, move rcur back out to .6585 No other PCS changes Result: plasma to 2sec, LH ok, runaways increase after LH Hint of a hesitation ion startup, but doesn't bounce and no runaways. Also no locked mode. Next: increase current 900kA (adding a point to the run plan)
Jan 28 2011 01:30:47:320PM	1110128020	Steve Wolfe	shot#20: Increase Ip from 800 to 900kA Increase rcur to .6595 to reduce outer gap by 2mm again, per LH request Decrease pg3 level in seg1 from 50 to 40V, see what happens to hesitation Result: plasma full length, LH looks happy, startup a bit better. Next: Go to LSN, 800kA
Jan 28 2011 01:48:59:773PM	1110128021	Steve Wolfe	shot#21: Go to LSN, 800kA: turn off seg2, turn on seg3 Start modifying: Load wire 14 from seg2 (nl04) Copy PG3 waveform from seg2 to seg3 Load wire 16 from seg2 (Ip) and change from 900 to 800kA Extend TF pulse to 1.7sec Extend RCUR, CLEARIN, ZCUR, RXL, ZXL, RXU, ZXU to 1.7sec EOF (RXU,ZXU done by hand) Argon puff from .1 to .09sec No startup changes I'll be surprised if it ramps down, I just hope it makes it through the LH] Result: plasma disrupts in rampdown at 2sec, I may need to extend some gains LH faulting Next: Extend gains and integrator gates to 2.5sec, decrease outer gap per LH recommendation
Jan 28 2011 02:06:33:410PM	1110128022	Steve Wolfe	shot#22: Extend gains and integrator gates to 2.5sec in seg3, but we will run the locked mode cal shot in seg 4 first; increase Ip point at 0.1sec back to 600kA, and turn on seg4, off seg3 If this goes, then we'll go back to seg3 and reduce outer gap by 5mm Result: plasma to 1.6sec, I guess it locks, looks like it may lock early but SL thinks it's ok Next: Back to segment3, increase RCUR by 2.5mm
Jan 28 2011 02:23:40:240PM	1110128023	Steve Wolfe	shot#23: Turn off seg4, turn on seg3 Extended gains and integrator gates to 2.5sec in seg3, reduce outer gap by 5mm: RCUR from .659 to .6615 Trying for LSN, 800kA, first point in scan#3 Result: fizzle. looks like too much gas after preceding disruption. Breakdown may be a little late at 6.8msec, Bz trending positive? Next: Reduce PG4 from 65 to 60msec
Jan 28 2011 02:37:57:467PM	1110128024	Steve Wolfe	shot#24: Reduce PG4 from 65 to 60msec, leave EF4 alone this time Relative to #23: Turn off seg4, turn on seg3 Extended gains and integrator gates to 2.5sec in seg3, reduce outer gap by 5mm: RCUR from .659 to .6615 Trying for LSN, 800kA, first point in scan#3 Result: plasma still disrupting at 2 sec, LH still not happy Startup looks ok. Not sure what's still turning off at 2sec, but it looks like something is. Next: change gap or something to help LH
Jan 28 2011 02:50:27:600PM	1110128025	Steve Wolfe	shot#25: Reduce gap by 5mm more: RCUR from .6615 to .664 Don't worry about the rampdown at this point. Result: plasma to 2sec, Looks like LH was better that time That's point #1 in the LSN current scan Next: reduce current to 700kA
Jan 28 2011 03:05:12:960PM	1110128026	Steve Wolfe	Shot#26: reduce current from 800 to 700kA No gap change, extend the Ip integral gain to 2.5sec, although it wasn't extended in seg2; I don't think this matters, but we'll see. Result: Plasma to 2sec, LH seems ok, small glitch in current near 0.1sec. Density rise during LH is larger than earlier USN shots. Next: go on to 600kA
Jan 28 2011 03:23:47:240PM	1110128027	Steve Wolfe	Shot#27: reduce current from 700 to 600kA Increase gap by 2mm, RCUR from .664 to .663 It looks like lots of gains in the long pulse seg2 were actually turning off at 2sec as well. Maybe I'll just ramp it down faster. Result: plasma to 1.99 sec, down to < 100kA at end. LH faults out half-way through pulse. Next: Increase the gap by 4mm
Jan 28 2011 03:33:38:003PM	1110128028	Steve Wolfe	Shot#28: Increase the gap by 4mm: RCUR from .663 to .661 Trying to make the LH happy with the density in front of the launcher. Result: plasma full length, LH stayed on, density still up near 5e19 during LH. Next: Take Ip down to 500kA, probably tweak the gap
Jan 28 2011 03:56:49:570PM	1110128029	Steve Wolfe	Shot#29: Take Ip from 600 to 500kA, Increase gap by 3mm: RCUR from .661 to .6595 Breakdown on 28 was a tiny bit late, 6.6msec, consider taking ef4 to -1300, but leave it for another shot Result: plasma full length, LH stayed on Breakdown moved earlier again, leave the field alone Next: decrease Ip to 300kA (skipping 400 for now)
Jan 28 2011 04:09:32:037PM	1110128030	Steve Wolfe	Shot#30: decrease Ip from 500 to 300kA (skipping 400 for now) Reduce V_oh1 in seg3 from 250 to 150V Increase gap by 5mm: RCUR from .6595 to .6570 Result: plasma full length, marfing all the way. LH had a couple of faults, but recovered. Density came down a bit, may have had a locked mode Next: Try reducing pg3 in seg2 to avoid marfe, which may get higher density back. Counterintuitive, but...
Jan 28 2011 04:23:41:737PM	1110128031	Steve Wolfe	Shot#31: Reduce initial pg3 puff in seg3 from 50 to 35 Slow down Ip ramp down from 550kA to 300 to BOF at .4sec (was .3sec) Increase gap by 2mm more, per LH request: RCUR from .657 to .656 While I'm at it, hold ZXU up longer in rampdown. Result: plasma full length, marfe under control. LH stayed on this time. Density looks ok SL is happy with rotation result. Next: go up to 400kA
Jan 28 2011 04:39:47:907PM	1110128032	Steve Wolfe	Shot#32: Current from 300 to 400kA leave gas programming as on #31. LH recommends leaving gap as is Result: plasma full length, quick marfe flashes by injections before LH, but everything survives. LH stays on ok. Injection takes a bite out of Te, raises density some Next: repeat, hopefully without injections.
Jan 28 2011 04:52:15:017PM	1110128033	Steve Wolfe	Shot#33: repeat at 400kA, hopefully without injections. Result: plasma full length, no injection, LH stays on Density looks ok, should be a valid data point. Next: Current to 350kA
Jan 28 2011 05:08:06:683PM	1110128034	Steve Wolfe	Shot#34: Current from 400 to 350kA Result: plasma full length, LH stayed on Breakdown a little late, but clean No injections, only a small marfe, density trace looks good. Should be a valid datapoint. Yuri says it's co=current, consistent with values at 300 and 400kA End of Run
