Jul 15 2002 12:58:05:113PMJim IrbySetting up to run data cycles to test gas puffs and neutral pressure
gauges. J-Bottom should be operational again. Possibly one new
ratiomatic.
Jul 15 2002 12:59:31:290PMJim IrbyDid cold start:

rtnode -- data loaded, A matrix responds
rtnode -- data loaded, M matrix responds
rtnode -- data loaded, PID matrix responds
RT_NODE Done
15-JUL-2002 12:58:42.88

No errors indicated from Hybrid
Jul 15 2002 02:28:22:457PM1020715001Jim Irbyg-side ratiomatic controller has been replaced with Willy's new controller --- will need to check
calibration very carefully

pulse_gas5 (j-bottom) has been set to turn on from 0.150 to 0.200 s

This shot is just a data system test --- no valves enabled

Note: even with nothing connected to the hard x-ray camac I have 200mV 120Hz noise spikes.

Jul 15 2002 03:16:59:313PM1020715003Jim Irbyg-side ratiomatic was working for this shot ---- 1.34e-6 Torr with IGT at 1.1e-7 Torr.

no gas enabled but we did see a very small pulse at -3 seconds.
Jul 15 2002 03:45:42:107PM1020715004Jim IrbyGas valves enabled. Should have lots of gas

pulse widths too short
Jul 15 2002 03:45:59:107PM1020715005Jim Irbypulse widths too short
Jul 15 2002 04:40:33:457PM1020715007Jim IrbyWe got some calibation data from c-side, j-bottom, and b-top.
This shot was done with the gatevalve toggle enabled.
