Ring heater test on ITMX this evening. 2W/segment for 2 hours.

TJ, Camilla

After we adjusted the HWS ITMX alignment today 92183, this evening I shuttered green, took new IX HWS references, removed some dead pixels from the camera (wiki link), and started the IX HWS code.

We are running a ring heater test with 2W/segment for 2 hours this evening. Using script below on tmux session:

  • python3 /tcs/common/scripts/power_adj_scripts/ring_heater_schedule.py ITMX -s  'now' -d 2 -p 2.0  -ep 0.44

Ring heaters should be back to nominal by ~11pm and fine for locking tomorrow. Purpose of this is to check HWS alignment before we align the ITMX CO2 (done for ITMY in 91616).
