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:
- 2006 LN2 Precool
- 2006 Full 3-day cool
- Old plot (2002)Note CCC stages cool fastest. The May ’07 warmup is here: 5-day plot
- Cryostat Control Software (internal use only)
- Using the Turbovac Pump – mounted on UIST (photo available here).
Monitoring and Maintaining UIST’s Performance
- Brief ENGINEERING HISTORY
- Telescope APERTURES and FOCI
- Running UIST with UCLIENT (same as WFCAM) or a web version
- Checks after instrument put back on to the telescope
- Plots of array perfomance: readnoise and dark current
- Useful configuration files – where these are!
- Some PHOTOS of UIST – internal and external
- Array Readout, DAC Boards, Cabling and the Controller
- DOCUMENTS – Grims, Slit, Filter, controller, etc.
- Chris’ “anything and everything” notes…
