UIST Temperatures and Pressures
-
Temperature plots - remote
-
Temperature and pressure plots - more extensive, but can't display remotely.
- At the telescope: type dm all.dl. Note chan 2 and 3
pressures usually e-04 and e-07.
- At home: login to OHI and tail
/jac_logs/epics_data/uistLogs/uist.txt. Values are listed as
Chan 1, Chan 2 (the array), HEATER (usually 20-30%), range, optics
bench (slow to change), wiring pole, 1st stage cold-head (55K), 2nd stage
cold-head (13K). The two stages on the cold-head (CCC) usual increase first,
especially if its a cold-head problem or dead chiller/compressor.
- Cooldown plots:
Note CCC stages cool fastest. The May '07 warmup is here: 5-day plot
