| Mar 20 2000 03:56:31:077PM | Steve Wolfe | Begin setting up a shot for power systems testing. Start from 991103014 (a long, reversed-field plasma from last year. Load/clean, just to put something in the model. | |
| Mar 20 2000 03:58:59:263PM | Steve Wolfe | Load from 990120019 - normal field, coil test sequence in seg 1 Start flipping - It is garbling the data when I do a flip. Seems to be a PCS bug, possibly IDL5.2, but not obviously. Some traces seem ok, others lose points and/or get mangled. Josh contacted - he''s doing some sort of demo right now. | |
| Mar 21 2000 08:05:21:030AM | Steve Wolfe | LOad from 990120019, and flip all the supply voltages and currents. PCS / IDL bug is not completely fixed; I need to set at least one why value to 0.0 to keep it from failing. Note: Josh determined that there is a bug in IDL v5.2 which causes it to recognize a value "-0." and turn it into garbage on conversion to/from vaxfloat. He has installed a workaround. This could be a real pain! Zero out the other three panels. Build all Save as cmod$root:[hybrid.pcs] 1000321999 - Bomb! it fails on the 10-digit number save as pcs$wolfe 999 instead. | |
| Mar 21 2000 08:15:33:747AM | Steve Wolfe | Do a coldstart. all matrices respond ok. Take a test shot #2 with existing model (loaded yesterday from 991103014) Looks ok. Load the coll test shot. Take test shot #3: looks ok, except for crosstalk on the pulsed gas lines at the 1V level (out of 100V fs). I think we are ready for testing. Note that a satisfactory plasma start shot is now in pcs_002 | |
| Mar 21 2000 11:48:46:607AM | 1000321001 | Steve Wolfe | shot#1: Btop hybrid enabled. Otherwise, a no power cycle. gas puff works on pre-puff. Next shot: EF4 test |
| Mar 21 2000 12:04:33:123PM | 1000321002 | Steve Wolfe | shot#2: EF4 test, bside upper got some gas from b-side upper. |
| Mar 21 2000 12:37:59:263PM | 1000321003 | Steve Wolfe | shot#3: b-side lower on hybrid enable. The live pc on the power supplies is not working. replace it with a scope, and test gas went ok. |
| Mar 21 2000 12:53:54:547PM | 1000321004 | Steve Wolfe | shot#4:c-side on hybrid enable. EF4 PLC test 2000a Rhone has been moved to the engineering side, but it needed its ethernet card changed, so the IDL license isn''t valid. Therefore, analysis tasks running on it are moved to spanna. got gas and current. looks good |
| Mar 21 2000 01:04:34:640PM | 1000321005 | Steve Wolfe | shot#5:j-bot on hybrid enable. EF4 PLC test 2000a, reverse bridge no gas, got reverse current. Next shot ef2u. |
| Mar 21 2000 01:24:42:653PM | 1000321005 | Steve Wolfe | shot#6: ef2u test. Nothing went, no pulses were created? But they got permissives? On previous shot, hybrid camac failed except for seven channels. Next shot: restart cycle and watch action monitor. |
| Mar 21 2000 01:51:38:997PM | 1000321008 | Steve Wolfe | shot#8: ef2u test. Tom says the disk was full, although I looked and didn''t see one. He says to try again. got current on ef2u. f17 is back on the hybrid inputs, Bob still not getting signal on the tr16. |
| Mar 21 2000 01:57:35:780PM | 1000321009 | Steve Wolfe | shot#9: ef2l test. and try J-bot gas again no gas, got ef2l current ok |
| Mar 21 2000 02:34:12:280PM | 1000321012 | Steve Wolfe | shot 12: Invert the chopper demand signal again (shouldn''t have been flipped?) That time it worked. Either I didn''t invert it the first time, or I did and shouldn''t have. Check the logic later, it works this way. |
| Mar 21 2000 02:43:28:543PM | 1000321013 | Steve Wolfe | shot 13: oh2u test. looks ok. next shot: reverse bridge |
| Mar 21 2000 02:52:56:077PM | 1000321014 | Steve Wolfe | shot 14: oh2u test. reverse bridge ok. |
| Mar 21 2000 03:03:04:763PM | 1000321015 | Steve Wolfe | shot 15: oh2l test - looks ok |
| Mar 21 2000 03:13:03:810PM | 1000321016 | Steve Wolfe | shot 16: oh2l test - reverse bridge looks ok |
| Mar 21 2000 03:22:44:810PM | 1000321017 | Steve Wolfe | shot 17: oh1 test - looks ok |
| Mar 21 2000 03:31:23:450PM | 1000321018 | Steve Wolfe | shot 18: oh1 test - reverse bridge ok |
| Mar 21 2000 03:39:09:170PM | 1000321019 | Steve Wolfe | shot 19: ef1u test ok next shot: reverse bridge |
| Mar 21 2000 03:48:46:340PM | 1000321020 | Steve Wolfe | shot 20: ef1u test reverse bridge looks ok. next shot: ef1L |
| Mar 21 2000 03:56:11:827PM | 1000321021 | Steve Wolfe | shot 21: ef1L test ; ok |
| Mar 21 2000 04:04:42:390PM | 1000321022 | Steve Wolfe | shot 22: ef1L test reverse bridge: looks good. Ready for tf tests. |
| Mar 21 2000 04:13:41:497PM | 1000321023 | Steve Wolfe | shot 23: TF 50ka test ok. |
| Mar 21 2000 04:26:23:437PM | 1000321024 | Steve Wolfe | shot 24: TF 100kA ok - 100kA, looks good |
| Mar 21 2000 05:04:09:437PM | 1000321025 | Steve Wolfe | shot 25: TF 150kA OK, 150kA, fizzle detector didn''''t take it out until 1sec? Fizzle detector didn''''t fire at all. It was working up until shot#23, when it started getting flakey, was delayed on #24, and didn''''t go at all on #25. It seems to have something to do with the tf tests? There is a large negative offset (~.12V) on the rogowski signal at the hybrid. This is apparently enough so that the tf pickup (~30mV) pushes it past the threshold. We need to tweak this up. Can do this either at the iso-amp in the cell or at the fizzle board in the interface room. Need schematics to see what pot to adjust either way. |
| Mar 21 2000 05:22:07:780PM | 1000321026 | Steve Wolfe | shot 26: EF4 under hybrid control, double swing +/- 750A (per coil) looks like it did it, although the reverse waveform is a little ragged. It looks like it overshoots during crossover, then rings a bit. Probably doing the expected thing. Note: the digitized hybrid signal at the supply seems to be missing. |
| Mar 21 2000 05:40:36:187PM | 1000321027 | Steve Wolfe | shot 27: oh commutation test (all three) under PLC control. looks ok. Next, ef1''s comm test |
| Mar 21 2000 05:52:04:030PM | 1000321028 | Steve Wolfe | shot 28: ef1''s comm test (plc control) looks good. That''s a wrap! |
