Operator Report - Morning shift

06:00 UTC ITF found with the following loops open:

  • top stage IB, OB, PR, SR, BS, NI, WI
  • F7 BS, WI
  • LC BS
  • Position and angular SPRB, SDB2, SNEB, SEWB

ITF was put in DOWN with ITF_LOCK and INJ_MAIN nodes in pause.

I was able to close some of them but SIB1 and WI had too high a correction to hold. Manuel started working on the issue while I called Valerio (work in progress), since we noticed that many stages of different suspensions were close to saturation and needed to be moved with motors.

SBEs closed.

08:15 UTC I changed the TCS Aux cooling chiller setpoint from 17 to 16.1. Heating loop setpoints: WI 17.4, NI 17.2. CO2 CH powers are back to before adding glycol.

10:00 UTC ALS NE malfunction assessment: L1 power supply not working (Cavalieri, Spinicelli)

12:00 UTC ITF in LOCKED_ARMS_IR
