| Physop Summary 971029 PO Hutch EO Silva/Bertolino. Completed power supply testing. Corrected an EF4 problem and checked it out. Discovered a problem with some of the new alternator instrumentation but it is not crucial to operations and can be fixed at leisure. Exercised gas valves. Ran TF under hybrid control. Shot 28 A full scale shot with all power supplies performing close to nominal. A very poor null because of Br offset (corrected), and Bz offset. Unfortunately this last shot had and instrumentation self-destruct when the ross relays closed prematurely, terminating the run.

OH PLC test at 10 kA. Compare volts scope looks fine.

Real time is back. Ports were swapped. OH2U has very substantial voltage ripple on it: 60 V. (OH2L 30V p-p). Period is 18ms. This ripple should not be present. -------------------------------------------------------------------------------- 971029004 HUTCH PHYSICS_OPERATOR 29-OCT-1997 10:01:11.36 . . . . . . . . . . . . . . . . . . . . EF2 and 1 test PLC. EF1U has a line frequency ripple of about 60 V not unlike the OH2 . Looked at 970624005 (a plasma shot) it has no line ripple. 970626013 which is an EF1 only test has a line ripple similar to the current shot. This suggests that this ripple is somehow introduced by the PLC control. -------------------------------------------------------------------------------- 971029006 HUTCH PHYSICS_OPERATOR 29-OCT-1997 10:09:05.70 . . . . . . . . . . . . . . . . . . . .

EF2 test on Hybrid control. Unchanged program, all off except EF2, invert at 0.1s. Looks ok. Draw in inverting waveforms on segment 1 for OH1,2, EF1.

Cut the gas programming from shot 27 into the Voltage for gas puff. Turn off the nl04 feedback, because the interferometer is not working. (Was 4). Lots of alarms go off. Null fairly dreadful. Br=+3mT Bz=+4mT. EF4U has -100A more than EF4U. -------------------------------------------------------------------------------- 971029028 HUTCH PHYSICS_OPERATOR 29-OCT-1997 16:43:23.94 . . . . . . . . . . . . . . . . . . . . In view of the Br we are seeing, lowered the Br offset from .0065 to .003 T. However, run ends because of various instrumentation problems. |
