Physop plan for Thursday, March 22,2007 Prepared by smw on behalf of Ian Hutchinson ECDC overnight in D2, 2e-4 Torr, Sweep Rmin=44cm Rdwell=45cm Rmax=103cm Bake at 60C Engineering Setup: Power Systems as on 1070321032 Acoil config +Dtop -Dbot -Jtop +Jbot Enabled Gas setup: fill B-top 6psi D2 Hybrid Enabled(PG4) fill B-side lower 1 psi Argon Hybrid Disabled (PG1) leave B-side Upper as is, Hybrid Disabled (PG2) fill B-main 40psi D2 Hybrid Enabled(PG3) NINJA pumped out, Disabled TORVAC pump gate valves open during pulse Enable the following diagnostic gate valves and shutters, assuming no vacuum problems: ECE, VUV, Z-bolo shutter. ICRF setup: None Physop plan: ------------- Start from 1070321034 (800kA, LSN, decent startup on Wednesday). Tune startup to taste, aiming for most reliable startup, preferably without runaways. Run lower null discharges until it gets boring (hopefully), then Change to Limiter discharges to do better scouring of inner wall, and If things are going really well go to upper null; try to get Brian to monitor upper probes during any upper null shots.

SL summary for Thursday, March 22, 2007 MP#298a C-Mod Startup SL: wolfe PO: Hutch,Granetz The run got off to an excellent start and then went really bad, really fast. The first five shots were successful full length 800kA lower nulls, which showed signs of cleaning up. We then hit a string of fizzle (late breakdown) and 3 duds that Ian blamed on the sparker, probably correctly. We got a plasma back on shot#10 after Jim increased the sparker voltage. However shot#11 was another dud and after Jim increased the voltage once again disaaster struck. On shot 12 there was evidence of big noise false triggers on numerous signals, and the bus rogowskis for the OH2 and TF currents went berserk. Since the bus rog signals are used by dpcs for feedback control in pre-charge and in the fizzle sequence, the oh2's were driven to their current rails. During the fizzle sequence they actually ended up at opposite polarity full currents, while the oh1 double swung normally. The problem was exacerbated by the baseline subtraction routine in dpcs, which ended up subtracting ~10V from the signals, somehow ending up with the bipolar demands trying to reach +15kA on each. The bus rog problem was still present on test shots after shot12, including a PLC control oh2 test (shot 13). No permanent fault was found, and after a couple of rounds of pulling out cables and integrator boards and putting them back in the problem went away. Very unsatisfying! We took additional tests including PLC tests on shots 15 and 16 before risking another dpcs control shot. This is a very scary fault scenario that we have never encountered before. It is probably possible to make dpcs check baseline values for out of range levels in baseline_sub and force an abort (jump to end or something) to avoid this condition, but I need to think about how to implement it safely. For shot 17, in a superabundance of caution, we had the EO lower the reverse bridge PLC current limit on all three OH supplies to 15kA, hoping to minmize the potential damage of a repeat of the behavior of shot 12. The shot ran normally until it ran into these current limits at ~1.5sec, then disrupted. The fact that JR convinced Bob to turn on the argon puff on 17 probably didn't make things any worse, but it didn't help. The disruption stirred up a lot of dirt (mass 18, 44, 28, ...). Mass 18 went up by over an order of magnitude, and stayed high for a long time. This was the last plasma we got all day. Shots 18-28 were a series of duds and fizzles. We ran ecdc after shot#23, and Jim found that the sparker supply had tripped off at some point, possibly after 17. However, we continued to get only fizzles after it was turned back on and the ecdc was completed. Probably the fizzles can be blamed on dirt generated by the disruption, but it is possible something more serious is wrong. We should see based on what happens tomorrow morning, after an overnight of ecdc. Meanwhile, a new cable has been installed on the sparker, connected to the other HV supply, and Jim says it seems to be behaving "correctly".

Run summary for Thursday 22 March 2007 MP# 298a: Startup Session leaders: S. Wolfe Physics operator: I. Hutchinson (shots 1-11) / R. Granetz (shots 11-28) Ian started the day with 5 full-length plasmas in a row. Then things decrapitated. Fizzles and duds, interrupted by a problem with the bus Rogowskis for the OH2's and the TF. This problem caused a problem with DPCS feedback control of the OH2's on shot 12. There were also DAQ problems a number of seemingly unrelated signals, such as the G-side ratiomatic. It may of been coincidental, but this problem was immediately preceeded by Jim Irby's tinkering with the sparker HV cable, and hearing a ""zap"". It took several data system cycles and no-power tests to convince ourselves that it was okay to continue with plasma operation. We got a long plasma on shot 17, which disrupted just after the start of rampdown. And then it was back to fizzles and duds. Scorecard: 7 plasmas 8 duds 8 fizzles 3 power supply tests 2 no power MDS shot cycles -------------- Total: 28 shot cycles

Session Leader Comments
Mar 22 2007 09:24:42:527AM	1070322001	Steve Wolfe	Shot#1: Plasma full length, very nice startup but f01 is reporting 20mV offset, along with f11; that's bad. Nl04 is flat at 6.3e19, no pg3 puff yet.
Mar 22 2007 09:37:05:573AM	1070322002	Steve Wolfe	Shot#2: Another plasma, a few runaways EFIT shows larger than normal chisq (~2) on flux24 (F25) and flux_09 (F10), along with flux_17 (F18) which is normally high. No sign of baseline offsets on the raw signals. Mflux plots look normal.
Mar 22 2007 09:50:07:963AM	1070322003	Steve Wolfe	Shot#3: Three in a row - a new record (this year) Hards are getting worse; small bounce. GPC2 now working, GPC1 otl. Vloop just over 1V. NL04=6.2e19, no pg3 in flattop.
Mar 22 2007 10:01:13:713AM	1070322004	Steve Wolfe	Shot#4: Plasma, Ian is getting bored; Hards down by factor of ten EFIT now shows chisq high on flux_21 (F22) flux_24(F25) and flux_09 (F10), in addition to flux_17. NL04=6.4e19, but got a little bit of pg3 feedback at .3 to .4 sec, couple of little blips later.
Mar 22 2007 10:17:33:400AM	1070322005	Steve Wolfe	Shot#5: Plasma. Lots of runaway. Another delayed trig on bolos and neuts/hards not on zmeter. flux_09 is still reporting chisq>2, flux_21 over 1. loop voltage still around 1.0V Next: reduce inner gap (from about 1cm)
Mar 22 2007 10:29:07:027AM	1070322006	Steve Wolfe	Shot#6: reduce inner gap (from about 1cm to .5cm) Fizzle. Ian left the room.
Mar 22 2007 10:39:55:400AM	1070322007	Steve Wolfe	Shot#7: repeat for reduced inner gap (from about 1cm to .5cm) Dud. Ian is blaming the sparker.
Mar 22 2007 10:54:59:260AM	1070322008	Steve Wolfe	Shot#8: repeat for reduced inner gap (from about 1cm to .5cm) Another dud, bz came down as programmed.
Mar 22 2007 11:05:20:573AM	1070322009	Steve Wolfe	Shot#9: Another dud. Jim will go in the cell to inspect the sparker.
Mar 22 2007 11:41:04:253AM	1070322010	Steve Wolfe	Shot#10: Plasma came back after increasing sparker voltage Bouncer with hards. Pg3 puff very marginal throughout the shot. Ratiomatic is noisy, maybe pickup from sparker. next: decrease inner gap again.
Mar 22 2007 11:51:17:710AM	1070322011	Steve Wolfe	Shot#11: decrease inner gap again. Dud. Jim says sparker is still close to 1mA.
Mar 22 2007 12:20:40:540PM	1070322012	Steve Wolfe	Shot#12: decrease inner gap again. Bob now in as physop, and will raise pg4 to 24msec (from 20) Something bad happened to oh2 bus rogs (camac and dpcs) and tf rog on that shot.
Mar 22 2007 12:49:33:430PM	1070322012	Steve Wolfe	Shot#12: Shunt signals indicate the oh2's went to their PLC limits on that shot. DPCS demand on oh2L was full out on negative voltage through shot oh2U is full negative before commutation then reverses ok. This means that after 80msec the oh2's went to opposite rails. TF rog was bad, but it's on current control so it ran ok.
Mar 22 2007 01:12:42:947PM	1070322013	Steve Wolfe	Shot#13: OH2U and OH2L forward bridge 10kA PLC test to check supplies, coax resistance, amd whether the bus rogowskis are in fact fixed. Rogowskis are still bad on both oh2's and tf Fizzle detector may not have worked either.
Mar 22 2007 01:45:15:713PM	1070322014	Steve Wolfe	Shot#14: No power cycle to see if the rogowskis are showing up bad with no inputs. Test shots look ok. The signals in question include at least three different integrator cards (the oh2u varistor rogowski also had a problem on shot13). Rog signals look fine. Next: another oh2 plc test
Mar 22 2007 01:57:01:210PM	1070322015	Steve Wolfe	Shot#15: PLC Oh2 test again. These look ok.
Mar 22 2007 02:05:47:477PM	1070322016	Steve Wolfe	Shot#16: PLC tf test Still trying to confirm that rogs are now working, because nothing has been done beyond unplugging and plugging cables and pulling and re-seating boards. That looks ok, TF trace is good, oh baseline is near zero with no slope.
Mar 22 2007 02:32:33:807PM	1070322017	Steve Wolfe	Shot#17: Limit reverse bridge currents on OH1,OH2U,OH2L to 15ka (from 26 and 27). Set up for plasma. plasma to 1.45sec; it did hit the current rails on the oh's. LOts of runaways. 2mm inner gap. JR talked Bob into letting him have an argon puff. Next: go limited.
Mar 22 2007 02:40:31:697PM	1070322018	Steve Wolfe	Shot#18: PLC current limits back to normal; try for limited plasma. dud.
Mar 22 2007 02:55:03:993PM	1070322019	Steve Wolfe	Shot#19: PLC current limits back to normal; try for limited plasma. another dud, despite higher fill. Br now looks too negative, and Bz is a little positive.
Mar 22 2007 03:04:22:197PM	1070322020	Steve Wolfe	Shot#20: PLC current limits back to normal; try for limited plasma. Another dud.
Mar 22 2007 03:24:46:167PM	1070322021	Steve Wolfe	Shot#21: fizzle
Mar 22 2007 03:32:28:743PM	1070322022	Steve Wolfe	Shot#22: dud.
Mar 22 2007 03:57:57:680PM	1070322023	Steve Wolfe	Shot#23: Very weak fizzle. We are going to ecdc for 15minutes Jim went down to check on the sparker, and reports that it was tripped off. Not sure how long ago this happened because the camera that was looking at it had died, possibly at the same time.
Mar 22 2007 04:13:10:710PM	1070322024	Steve Wolfe	Shot#24: No power shot, to be sure turning the sparker back on didn't screw up the rogowskis again. Rogowskis look ok, try for plasma again.
Mar 22 2007 04:31:56:510PM	1070322025	Steve Wolfe	Shot#25: Still trying to get a limited plasma case. fizzle. breakdown time is good, burnout is poor. Bz looks high. CIII signal is pretty low, so is zmeter.

Physics Operator Comments
Mar 22 2007 09:12:29:463AM		Ian Hutchinson	Only PCS changes from yesterday: Lower PG3 puff to 42 from 50-100ms. Try to avoid the gassing out phenomenon. Gas fill puff to 20ms from 24ms. Remove Wolfe's last tweak. Gas is not the way to avoid runaways on a permanent basis IMHO. Sparker has been worked on.
Mar 22 2007 09:27:04:853AM	1070322001	Ian Hutchinson	Plasma till 2s, complete ramp down. Looks very good.
Mar 22 2007 09:41:04:933AM	1070322002	Ian Hutchinson	Plasma till 2s. Delay the nl04 flat top start to .3s from .2s.
Mar 22 2007 09:58:41:103AM	1070322003	Ian Hutchinson	Plasma till 2s. Some runaways after a small bounce.
Mar 22 2007 10:16:29:713AM	1070322004	Ian Hutchinson	Plasma till 2s. Slight feedback puff shows we are beginning to get fueling under control.
Mar 22 2007 10:28:05:057AM	1070322005	Ian Hutchinson	Plasma till 2 seconds. Camac timing problem on bolo/neuts-hards. Drop Clearin by 5mm. Drop Rcur by 3mm. To move plasma closer to inner wall.
Mar 22 2007 10:39:50:370AM	1070322006	Ian Hutchinson	Fizzle. Late breakdown at 14ms. Sparker is highly suspect. No changes.
Mar 22 2007 10:54:43:637AM	1070322007	Ian Hutchinson	Dud.Bz a little higher. EF4 to -1355 from -1345A.
Mar 22 2007 11:04:55:917AM	1070322008	Ian Hutchinson	Dud. Take 200V off first 2 EF3 voltage points.
Mar 22 2007 11:40:02:500AM	1070322009	Ian Hutchinson	Dud. Entry to increase the voltage on the sparker.
Mar 22 2007 11:48:36:630AM	1070322010	Ian Hutchinson	Plasma to 2 sec. Slight continuing puff. EF3 back to 2800V at 5ms. Clearin to -9mm (drop 5mm), Rcur dropped 3mm.
Mar 22 2007 11:50:37:150AM	1070322011	Ian Hutchinson	Dud.
Mar 22 2007 12:04:04:180PM	1070322012	Robert Granetz	Granetz taking over as physop for Ian prior to this shot.
Mar 22 2007 12:05:15:853PM	1070322012	Robert Granetz	Prior to this shot I increased PG4 by 4 ms (20 --> 24 ms). Jim Irby also went into the cell and played with the sparker cable.
Mar 22 2007 12:16:47:947PM	1070322012	Robert Granetz	Shot 12 -- Fizzle. G-side-ratiomatic shows zero pressure, but I don't believe it. Next shot: reload segment 1 from shot 5. (This puts PG4 back to 20 ms.)
Mar 22 2007 12:19:28:727PM	1070322012	Robert Granetz	Actually, a number of the bus Rogowski signals look bad (OH2U & L, TF). These bad signals went into the DPCS.
Mar 22 2007 12:27:20:620PM	1070322012	Robert Granetz	Actually, the bad OH2L bus signal into DPCS caused OH2L to go to 34 kA. Jim Irby just took a test shot and the bus Rogowskis are still bad. Power room access granted to work on the bus Rogowskis.
Mar 22 2007 12:41:45:557PM	1070322013	Robert Granetz	Shot 13: OH2U & L test under PLC control. 10 kA.
Mar 22 2007 01:11:15:273PM	1070322013	Robert Granetz	Result: OH2U & L bus Rogowskis are still bad. So is the TF.
Mar 22 2007 01:47:57:210PM	1070322014	Robert Granetz	Shot 14: test of bus Rogowskis, with no coil currents. They look okay. We also puffed gas, and the G-side ratiomatic is working properly.
Mar 22 2007 01:57:28:010PM	1070322015	Robert Granetz	Shot 15: Another OH2U & L test under PLC control. This time the bus Rogowskis look good. Next shot: 50 kA TF-only test to check its bus Rogowski.
Mar 22 2007 02:16:37:150PM	1070322016	Robert Granetz	Shot 16: TF-only test. 50 kA, PLC control. TF bus Rogowski signal looks good. Next shot: go for plasma. I've enabled an argon puff for John Rice (t=0.300-0.350 s). Also, the PLC reverse current limits on the OH1 and OH2's has been reduced to 15 kA just to be cautious for now.
Mar 22 2007 02:29:06:977PM	1070322017	Robert Granetz	Shot 17: Plasma. Disrupted at 1.5 seconds because the OH's hit their reduced rails. Lots of hard x-rays. This shot was almost inner-wall limited, as planned for shot 5. Next shot: reduce CLEARIN by 1.1 cm (from -9 mm --> -20 mm)
Mar 22 2007 02:39:06:837PM	1070322018	Robert Granetz	Shot 18: Dud. Fields look okay. Next shot: increase pre-fill by 4 ms (20 --> 24 ms).
Mar 22 2007 02:52:16:917PM	1070322019	Robert Granetz	Shot 19: Dud. Br0 is a little low. Next shot: increase Br0 offset by 0.5 mT (-0.0007 --> -0.0002 T)
Mar 22 2007 03:05:28:133PM	1070322020	Robert Granetz	Shot 20: Dud again. Next shot: subtract 15 amps from IC_EF4 (-1345 --> -1360 A)
Mar 22 2007 03:19:36:290PM	1070322021	Robert Granetz	Shot 21: Fizzle. Next shot: no changes.
Mar 22 2007 03:32:14:493PM	1070322022	Robert Granetz	Shot 22: Dud. Field null looks good. Next shot: raise pre-fill to 30 ms, at Steve's suggestion.
Mar 22 2007 03:43:47:557PM	1070322023	Robert Granetz	Shot 23: Fizzle, just barely. Set up to do 15 minutes of ECDC before the next shot. Also, Jim will go down and check the sparker. Next shot: reduce pre-fill gas puff back to 24 ms.
Mar 22 2007 04:08:34:120PM	1070322023	Robert Granetz	Shot 24 -- Prior to this shot, Jim went into the cell and played with the sparker, so we are going to have a no-power test shot to make sure that the bus Rogowskis and other DAQ are still working okay.
Mar 22 2007 04:13:42:603PM	1070322024	Robert Granetz	Shot 24 -- Test. No-power shot cycle to confirm that bus Rogowskis are still working after Jim played with the sparker. Bus rogowskis are working properly. Next shot: try for plasma again.
Mar 22 2007 04:27:01:383PM	1070322025	Robert Granetz	Shot 25 -- Fizzle. I think we need an overnight boronization, but we might as well get in the last 2-3 shot attempts. Next shot: no changes.
Mar 22 2007 04:49:28:620PM	1070322026	Robert Granetz	Shot 26 -- Fizzle. Next shot: reduce pre-fill to 20 ms.
Mar 22 2007 04:51:49:667PM	1070322027	Robert Granetz	Shot 27 -- Fizzle. Next shot: add 2 ms to pre-fill (to 22 ms)
Mar 22 2007 05:00:42:010PM	1070322028	Robert Granetz	Shot 28 -- Fizzle. End of run. Turn on the ECDC please!
