Engineering Setup and Physop plan for Tuesday, Nov 20 Power Systems Testing SL: Cochran,Irby PO: Wolfe Run begins at 9:00 AM (08:30 Lockup) The main purpose of this run is Engineering Power System tests. These will also provide fields suitable for checking out the replacement flux loops at F10, F11, and F19, as well as the remainder of the magnetics equilibrium diagnostics. Most of the testing will be carried out under PLC control. DPCS will be used for double swing EF4 testing, and to provide inputs for the Chopper test and the A-Coil tests. Gas puff tests will be carried out using DPCS program waveforms, as requested. Gas Setup: ----------- fill B-top 6psi D2 Hybrid Disabled (PG4) fill B-side lower 1 psi Argon Hybrid Disabled (PG1) fill B-side Upper as is, Hybrid Disabled (PG2) fill B-main 40psi D2 Hybrid Disabled (PG3) NINJA pumped out, Disabled * Valves will be Enabled for testing during the course of the day. Shot sequence for the power system testing will be determined by the Engineering operator. Magnetics signals, particularly those from the replaced flux loops will be monitored for polarity and amplitude during the PF testing. If these are ok, then the following steps could be done to start using them again: 1) Turn the corresponding INPUTs on in the Hybrid model tree, both under CONFIG and DPCS_CONFIG 2) Change \analysis::recon_vac:static_shot from 2014 to 2003 3) Change \analysis::efit_green:static_shot from 2007 to 2008 (Also in \efit) Change expressions in fwtsi in both \analysis::efit_efitin and \efit::efit_efitin. May need to change icalz as well? 4) CVS update /usr/local/cmod/codes/pcs/user_algs/contihh/ianup.pro to pick up the reversion to ian_001 for new shots 5) With the new ianup.pro in place, run usr/local/cmod/codes/mhd/fluxihh/load_predictors_procedure.sh to put back the predictors in the tree 6) Add a line to \hybrid::top.config:config_id to recalculate mag predictors. Note that it may be better to let the first plasma attempts use the same subset of flux loops that we ended up with in August, and then make the changes to turn the new ones on again. See logbook entry from Nov 16 01:28PM under DPCS and MHD topics. It is extremely unlikely that we will try for plasma on Tuesday, especially if the leak has not been found. In case we do get that far and decide to try, the following power system setup should be used: Power systems as on 1070830001 Acoil Configuration +Dtop -Dbot -Jtop +Jbot, Enabled Gas setup as above, except ENABLE B-top and B-main. TORVAC: Pumping Gate valves open Enable the following gate valves and shutters, assuming no vacuum problems: Z-bolo shutter. Check with Terry and/or Reinke before opening VUV ECE will NOT be available ICRF setup: None LH: none Physop plan: Try for plasma with the programming as on the target shot. Check null and magnetics signals on replacement flux loops. Once plasma is obtained, check EFIT reconstruction, chisq values of new loops. If not already done, update fluxihh predictors in analysis tree (/usr/local/cmod/codes/mhd/fluxihh/load_predictors_procedure.sh) and check startup signals and gap values during flattop. Get at least two consecutive successful startups before recalculating predictors to use the new loops. Probably start by only updating seg2 predictors.

Physop summary for Tuesday, Nov 20, 2007 Power system tests and C-Mod startup. SL: ? PO: wolfe EO: Dekow,Cochran,Byford Power testing went fairly smoothly, and was completed on shot 29. One remaining outstanding issue is that the TF bus rogowski is reading 10-15% low, compared to the shunt, and also to the Btor signal. The new replacement magnetics flux loops f10,f11,f19 seem to be working ok. No other active magnetics are reporting problems. MFLUX plots look reasonable, perhaps with a small up-down assymetry associated with f11. Shots 30 and 31 were plasma attempts, taken despite the fact that the air leak is still present with a base pressure of 3.6e-6Torr. Programming was taken from 1070830001, an 800kA successful shot from the next to last day of operation last summer. Both resulted in fizzles, with no current pickup and high CIII light. The zmeter isn't working. Flashes were not seen on the tv, either ch 33 or the h-port view. The mflux nulls looked reasonable, certainly better than they had been. The EFIT static shot was updated to 2008 before the plasma attempts. None of the other changes relative to the replacement loops were implemented during the run. After shot 31, we shut down the run in order to resume leak checking. There seems no point in continuing until the leak is fixed. Following the run, I completed items #1-4 of the steps listed in the po_plan for incorporating the replacement flux loops. EFIT, MFIL and RECON_VAC are ready to go using the new loops. Calling predictors using vacuum, filament, and fluxihh algorithms should generate predictors using the new loops. I have not yet updated the coefficients used for the analysis tree fluxihh predictors (including rcur,clearin, etc.) and I have not yet added a line to the \hybrid::top.config:config_id with instructions for changing the predictors. I'll do these tomorrow, assuming we run and get plasmas, which assumes the leak gets fixed. Scorecard: ----------- Tests 29 Duds 0 Fizzles 2 Plasmas 0 ======= == Shots 31

Following the run on Tuesday, Nov 20 Update /usr/local/cmod/codes/pcs/user_algs/contihh/ianup.pro This should cause mfil and the fluxihh algorithm for predictors to revert to the original ian tree which uses all the flux loops (in their nominal locations). Calling the predictors should now result in getting predictors with the right things loaded. I'll test that now. It seems to only retrieve ian shot version 1, which is correct. The predictor has entries for f10,f11 and f19.

Following the run on Tuesday, Nov 20 Try using recon_vac:static_shot=2003 on the Br0 trace for shot31. It is broken, at least in IDL. Also in scopes. It may be an IEEE float or library issue, the values are in the 10^22 range. This means I'm going to need to make a new one anyhow. The numbers for the coefficients don't look crazy IDL> print,mdsvalue('ANALYSIS::TOP:RECON_VAC:BR_0:MATRIX') 0.00100399 -0.105050 -0.0928029 -0.0386942 -0.0182297 -0.0251558 -0.00671100 -0.00594429 -0.0706493 -0.0332532 -0.0330985 0.0328775 0.0330541 0.0718021 0.00554995 0.00650418 0.0250986 0.0182487 0.0387873 0.0929127 0.103649 -0.496878 -0.484248 Ah, the problem is that the mag_data:signal is the wrong shape, because it was stored from the other static shot prescription Try again, and the value using 2003 comes out +.0005T compared to -.002T. The mflux value is coming out around -.0005T. Put the static shot value back in the pulse file. In the analysis model, set analysis::recon_vac:static_shot=2003. This will allow recalculation of vacuum predictors (br_0) and the recon_vac calculation in the tree will be consistent with the new predictors, and will hopefully be close to correct.

Nov 20 2007 09:28:19:233AM 1071120001 Steve Wolfe
shot#1: EFC test gas on for b-top only 59ms pulse at -.5sec hung up in INIT. Josh cleared it Only about 100A of efc, only got about 40V on vstatic Got gas. 0.12mTorr on ratiomatic.

Nov 20 2007 09:30:25:030AM 1071120001 Steve Wolfe
shot#1: EFC test Bit noise level blip on f10,f11 (both negative) and f19 (positive). Signs seem consistent with nearby loops. Can't tell anything from the magnitude; we only got about 40A of current.

Nov 20 2007 09:37:16:860AM 1071120002 Steve Wolfe
shot#2: EFC test repeat Got about 100amps, again looks like low voltage on all three TMX's.

Nov 20 2007 10:01:22:150AM 1071120003 Steve Wolfe
shot#3: Turn off B-top puff Bill and Gary changed a chip on the EFC regulator board Repeat EFC test Got current this time, about 800amps, looks normal. Torus pressure is rising (with gate valves closed) into the high e-5 scale at 1:30 into recool 1e-4 at 2:00 min magnetics signals look reasonable, between 5 and 9mWb on the new loops, correct polarity

Nov 20 2007 10:09:06:810AM 1071120004 Steve Wolfe
shot#4: 800V EFC test. Gary will restart the cycle, per jas Current looks ok again, voltage still seems to be 600V?

Nov 20 2007 10:22:50:080AM 1071120005 Steve Wolfe
shot#5: 800V EFC test with current limit at 2.5ka fizzle detector moved out. Got a nice flat pulse at 1700A, near 1000V. Looks good to me. magnetics look ok, f10=-36, f11=-27,f19=+22 f01 has nothing but bit noise, which may be ok since it's on the midplane. All other flux loops have visible signal.

Nov 20 2007 10:33:09:900AM 1071120006 Steve Wolfe
shot#6: EF2U test (PLC control) EF2U about -3kA, also +600A induced in ef3 all flux loops have signal, mflux looks reasonable.

Nov 20 2007 10:40:43:307AM 1071120007 Steve Wolfe
shot#7: EF2L test (PLC control) EF3L at -3kA, mflux looks reasonable Next: acoil test, dpcs control

Nov 20 2007 10:52:11:810AM 1071120008 Steve Wolfe
Shot#8: Setting up for acoil pulse. Load from 1070315001, get warnings and ack them This one had program for 1000A and 500A, but only got first levelto 550A because of offset. Increase levels to 1200,800, should get ~600 and 200. Ignore f10,f11,f19 warnings on wires 1,2,3,4,6,7 since we're not using these, and the loops are apparently ok anyway! Load at 20-Nov-2007 10:44:03.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done Got 775 amps and 300A looks good to me.

Nov 20 2007 11:04:29:347AM 1071120009 Steve Wolfe
Shot#9: On to EF3 test +2500A on EF3. Mflux looks ok, no obvious magnetics problems Next EF4

Nov 20 2007 11:14:01:790AM 1071120010 Steve Wolfe
Shot#10: EF4 forward bridge We finally noticed that the bigboard is not updating the shot number or the coil currents/voltages. Yuri is looking into it. -1000A on EF4. Vacbrbz Bz0 signal says -.051T, vac says -.046 mflux looks good. Next: reverse bridge

Nov 20 2007 11:23:50:307AM 1071120011 Steve Wolfe
Shot#11: EF4 reverse bridge No current. Didn't this happen last time?

Nov 20 2007 11:38:39:313AM 1071120012 Steve Wolfe
Shot#12: EF4 reverse bridge repeat Got 1000A positive, and induced 400A in EF3 on the shut off Next: EF4 double swing, load from 1070315020

Nov 20 2007 12:09:01:903PM 1071120013 Steve Wolfe
Shot#13: EF4 double swing, load from 1070315020 ignore f10,f11,f19 warnings on wires 1,2,3,4,6,7 Filling in configuration /31-JUL-2007 17:52:43.27/ Filling in DPCS configuration /31-JUL-2007 17:46:18.39/ about to ask alcdaq2 to copy /home/wolfe/pcs_scratch/pcs_model to /cmod/trees/models/pcs/pcs_model about to ask alcdaq2 to copy /home/wolfe/pcs_scratch/dpcs_model to /cmod/trees/models/dpcs/dpcs_model Load at 20-Nov-2007 11:39:52.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done Looks good to me. Well, no it doesn't. I'm only seeing -1100Amps and program is -1345 dpcs is showing -240A of error signal. voltage demaind is only -750V. Maybe doesn't have enough gain? It's at P=8. Gary says it looked the same in march. Move on, maybe need to come back to it Behavior explained, PLC current limit was at 2000A, but the coils are in parallel so should have been >2800 for that program. It was riding the current rail.

Nov 20 2007 12:05:42:400PM 1071120014 Steve Wolfe
Shot#14: EF1U forward bridge -1700A square pulse. Looks ok. mflux is reasonable

Nov 20 2007 01:05:21:660PM 1071120020 Steve Wolfe
Shot#20: OH2u forward bridge -2.5ka

Nov 20 2007 01:15:50:977PM 1071120021 Steve Wolfe
Shot#21: OH2u reverse bridge got -1000A (wrong direction???)

Nov 20 2007 01:26:14:183PM 1071120022 Steve Wolfe
Shot#22: OH2u reverse bridge repeat with correct sign of plc voltage setting +2700A, looks like more oscillation than in the forward direction ~400a P-P, compared to <100a for forward bridge.

Nov 20 2007 01:37:29:640PM 1071120023 Steve Wolfe
Shot#23: OH2L forward bridge -2600A, looks ok. Next: reverse bridge, ECE gate valve will be enabled, per Amanda

Nov 20 2007 01:57:17:883PM 1071120025 Steve Wolfe
Shot#25: EF1 commutation 2000A successful commutation Next oh commutation

Nov 20 2007 02:08:42:277PM 1071120026 Steve Wolfe
Shot#26: oh commutation 10kA commutation successful next do the TF's; first Gary needs an access

Nov 20 2007 02:47:37:937PM 1071120027 Steve Wolfe
Shot#27: 50kA TF test While I'm waiting, go ahead and load from 1070830001 change seg2 title to 0.8MA SNL Load at 20-Nov-2007 14:16:28.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done Note that the startup (still using 07 configuration) has EF4U = -1335 Br0 = -.0035 rcur = 700 pg4 = 20ms TF 50ka test looks good, no sign of a ground fault There may be a small (< 1mWb) assymetry between f11 and f17

Nov 20 2007 03:04:19:403PM 1071120028 Steve Wolfe
Shot#28: 100kA TF test only got 87ka on the rogowski Shunt claims it is 100kA, Bt says 3.51T, which implies the shunt is correct. May be a problem with the tf rogowski at the 10% level mflux br0 is positive by .5mT

Nov 20 2007 03:09:21:080PM 1071120029 Steve Wolfe
Shot#29: 150kA TF test rogowski reads 130ka, bt=5.24 Next: set up for plasma

Nov 20 2007 03:27:39:883PM 1071120030 Steve Wolfe
Shot#30: plasma attempt. same as above, except drop pg4 from 20 to 16ms Base pressure is still 3.6e-6 from air leak fizzle, got light but no current. CIII signal is .015, Halpha=0.6, zmeter dark mflx null looks fair. breakdown time 6.3ms I'm not sure we can do much better with the leak. try raising pg4 back to 20ms

Nov 20 2007 03:37:51:183PM 1071120031 Steve Wolfe
Shot#31: try raising pg4 back to 20ms fizzle, no current, light about the same. Shut it down and leak check.

Physics Operator Comments
Nov 20 2007 04:29:44:780PM		Steve Wolfe	Following the run on Tuesday, Nov 20 Update /usr/local/cmod/codes/pcs/user_algs/contihh/ianup.pro This should cause mfil and the fluxihh algorithm for predictors to revert to the original ian tree which uses all the flux loops (in their nominal locations). Calling the predictors should now result in getting predictors with the right things loaded. I'll test that now. It seems to only retrieve ian shot version 1, which is correct. The predictor has entries for f10,f11 and f19.
Nov 20 2007 05:25:14:740PM		Steve Wolfe	Following the run on Tuesday, Nov 20 Try using recon_vac:static_shot=2003 on the Br0 trace for shot31. It is broken, at least in IDL. Also in scopes. It may be an IEEE float or library issue, the values are in the 10^22 range. This means I'm going to need to make a new one anyhow. The numbers for the coefficients don't look crazy IDL> print,mdsvalue('ANALYSIS::TOP:RECON_VAC:BR_0:MATRIX') 0.00100399 -0.105050 -0.0928029 -0.0386942 -0.0182297 -0.0251558 -0.00671100 -0.00594429 -0.0706493 -0.0332532 -0.0330985 0.0328775 0.0330541 0.0718021 0.00554995 0.00650418 0.0250986 0.0182487 0.0387873 0.0929127 0.103649 -0.496878 -0.484248 Ah, the problem is that the mag_data:signal is the wrong shape, because it was stored from the other static shot prescription Try again, and the value using 2003 comes out +.0005T compared to -.002T. The mflux value is coming out around -.0005T. Put the static shot value back in the pulse file. In the analysis model, set analysis::recon_vac:static_shot=2003. This will allow recalculation of vacuum predictors (br_0) and the recon_vac calculation in the tree will be consistent with the new predictors, and will hopefully be close to correct.
Nov 20 2007 09:28:19:233AM	1071120001	Steve Wolfe	shot#1: EFC test gas on for b-top only 59ms pulse at -.5sec hung up in INIT. Josh cleared it Only about 100A of efc, only got about 40V on vstatic Got gas. 0.12mTorr on ratiomatic.
Nov 20 2007 09:30:25:030AM	1071120001	Steve Wolfe	shot#1: EFC test Bit noise level blip on f10,f11 (both negative) and f19 (positive). Signs seem consistent with nearby loops. Can't tell anything from the magnitude; we only got about 40A of current.
Nov 20 2007 09:37:16:860AM	1071120002	Steve Wolfe	shot#2: EFC test repeat Got about 100amps, again looks like low voltage on all three TMX's.
Nov 20 2007 10:01:22:150AM	1071120003	Steve Wolfe	shot#3: Turn off B-top puff Bill and Gary changed a chip on the EFC regulator board Repeat EFC test Got current this time, about 800amps, looks normal. Torus pressure is rising (with gate valves closed) into the high e-5 scale at 1:30 into recool 1e-4 at 2:00 min magnetics signals look reasonable, between 5 and 9mWb on the new loops, correct polarity
Nov 20 2007 10:09:06:810AM	1071120004	Steve Wolfe	shot#4: 800V EFC test. Gary will restart the cycle, per jas Current looks ok again, voltage still seems to be 600V?
Nov 20 2007 10:22:50:080AM	1071120005	Steve Wolfe	shot#5: 800V EFC test with current limit at 2.5ka fizzle detector moved out. Got a nice flat pulse at 1700A, near 1000V. Looks good to me. magnetics look ok, f10=-36, f11=-27,f19=+22 f01 has nothing but bit noise, which may be ok since it's on the midplane. All other flux loops have visible signal.
Nov 20 2007 10:33:09:900AM	1071120006	Steve Wolfe	shot#6: EF2U test (PLC control) EF2U about -3kA, also +600A induced in ef3 all flux loops have signal, mflux looks reasonable.
Nov 20 2007 10:40:43:307AM	1071120007	Steve Wolfe	shot#7: EF2L test (PLC control) EF3L at -3kA, mflux looks reasonable Next: acoil test, dpcs control
Nov 20 2007 10:52:11:810AM	1071120008	Steve Wolfe	Shot#8: Setting up for acoil pulse. Load from 1070315001, get warnings and ack them This one had program for 1000A and 500A, but only got first levelto 550A because of offset. Increase levels to 1200,800, should get ~600 and 200. Ignore f10,f11,f19 warnings on wires 1,2,3,4,6,7 since we're not using these, and the loops are apparently ok anyway! Load at 20-Nov-2007 10:44:03.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done Got 775 amps and 300A looks good to me.
Nov 20 2007 11:04:29:347AM	1071120009	Steve Wolfe	Shot#9: On to EF3 test +2500A on EF3. Mflux looks ok, no obvious magnetics problems Next EF4
Nov 20 2007 11:14:01:790AM	1071120010	Steve Wolfe	Shot#10: EF4 forward bridge We finally noticed that the bigboard is not updating the shot number or the coil currents/voltages. Yuri is looking into it. -1000A on EF4. Vacbrbz Bz0 signal says -.051T, vac says -.046 mflux looks good. Next: reverse bridge
Nov 20 2007 11:23:50:307AM	1071120011	Steve Wolfe	Shot#11: EF4 reverse bridge No current. Didn't this happen last time?
Nov 20 2007 11:38:39:313AM	1071120012	Steve Wolfe	Shot#12: EF4 reverse bridge repeat Got 1000A positive, and induced 400A in EF3 on the shut off Next: EF4 double swing, load from 1070315020
Nov 20 2007 12:09:01:903PM	1071120013	Steve Wolfe	Shot#13: EF4 double swing, load from 1070315020 ignore f10,f11,f19 warnings on wires 1,2,3,4,6,7 Filling in configuration /31-JUL-2007 17:52:43.27/ Filling in DPCS configuration /31-JUL-2007 17:46:18.39/ about to ask alcdaq2 to copy /home/wolfe/pcs_scratch/pcs_model to /cmod/trees/models/pcs/pcs_model about to ask alcdaq2 to copy /home/wolfe/pcs_scratch/dpcs_model to /cmod/trees/models/dpcs/dpcs_model Load at 20-Nov-2007 11:39:52.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done Looks good to me. Well, no it doesn't. I'm only seeing -1100Amps and program is -1345 dpcs is showing -240A of error signal. voltage demaind is only -750V. Maybe doesn't have enough gain? It's at P=8. Gary says it looked the same in march. Move on, maybe need to come back to it Behavior explained, PLC current limit was at 2000A, but the coils are in parallel so should have been >2800 for that program. It was riding the current rail.
Nov 20 2007 12:05:42:400PM	1071120014	Steve Wolfe	Shot#14: EF1U forward bridge -1700A square pulse. Looks ok. mflux is reasonable
Nov 20 2007 12:14:50:093PM	1071120015	Steve Wolfe	Shot#15: EF1U reverse bridge 2000A positive magnetics look ok
Nov 20 2007 12:25:00:330PM	1071120016	Steve Wolfe	Shot#16: EF1L forward bridge Bill will replace relays on comm circuits -2000A, magnetics look ok. next: reverse bridge
Nov 20 2007 12:36:47:883PM	1071120017	Steve Wolfe	Shot#17: EF1L reverse bridge +2000A, ok Next: OH1 forward bridge (wait on the commutations)
Nov 20 2007 12:45:32:607PM	1071120018	Steve Wolfe	Shot#18: OH1 forward bridge (wait on the commutations) -3kA
Nov 20 2007 12:53:54:140PM	1071120019	Steve Wolfe	Shot#19: OH1 reverse bridge +2kA, ok
Nov 20 2007 01:05:21:660PM	1071120020	Steve Wolfe	Shot#20: OH2u forward bridge -2.5ka
Nov 20 2007 01:15:50:977PM	1071120021	Steve Wolfe	Shot#21: OH2u reverse bridge got -1000A (wrong direction???)
Nov 20 2007 01:26:14:183PM	1071120022	Steve Wolfe	Shot#22: OH2u reverse bridge repeat with correct sign of plc voltage setting +2700A, looks like more oscillation than in the forward direction ~400a P-P, compared to <100a for forward bridge.
Nov 20 2007 01:37:29:640PM	1071120023	Steve Wolfe	Shot#23: OH2L forward bridge -2600A, looks ok. Next: reverse bridge, ECE gate valve will be enabled, per Amanda
Nov 20 2007 01:46:00:487PM	1071120024	Steve Wolfe	Shot#24: OH2L reverse bridge ECE gate valve requested enable +2300A
Nov 20 2007 01:57:17:883PM	1071120025	Steve Wolfe	Shot#25: EF1 commutation 2000A successful commutation Next oh commutation
Nov 20 2007 02:08:42:277PM	1071120026	Steve Wolfe	Shot#26: oh commutation 10kA commutation successful next do the TF's; first Gary needs an access
Nov 20 2007 02:47:37:937PM	1071120027	Steve Wolfe	Shot#27: 50kA TF test While I'm waiting, go ahead and load from 1070830001 change seg2 title to 0.8MA SNL Load at 20-Nov-2007 14:16:28.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done Note that the startup (still using 07 configuration) has EF4U = -1335 Br0 = -.0035 rcur = 700 pg4 = 20ms TF 50ka test looks good, no sign of a ground fault There may be a small (< 1mWb) assymetry between f11 and f17
Nov 20 2007 03:04:19:403PM	1071120028	Steve Wolfe	Shot#28: 100kA TF test only got 87ka on the rogowski Shunt claims it is 100kA, Bt says 3.51T, which implies the shunt is correct. May be a problem with the tf rogowski at the 10% level mflux br0 is positive by .5mT
Nov 20 2007 03:09:21:080PM	1071120029	Steve Wolfe	Shot#29: 150kA TF test rogowski reads 130ka, bt=5.24 Next: set up for plasma
Nov 20 2007 03:27:39:883PM	1071120030	Steve Wolfe	Shot#30: plasma attempt. same as above, except drop pg4 from 20 to 16ms Base pressure is still 3.6e-6 from air leak fizzle, got light but no current. CIII signal is .015, Halpha=0.6, zmeter dark mflx null looks fair. breakdown time 6.3ms I'm not sure we can do much better with the leak. try raising pg4 back to 20ms
Nov 20 2007 03:37:51:183PM	1071120031	Steve Wolfe	Shot#31: try raising pg4 back to 20ms fizzle, no current, light about the same. Shut it down and leak check.
