KAGRA morning information
(1) ADS for ETMXY using common/differential scheme succeeded.
- Because of this success, we changed the LOCK_LSC guardian process a little bit.
- LOCK_LSC guardian Process: Assuming from "DOWN" state
- (a) Down (as an initial condition)
- (b) Push "PRFPMI_LSC_LOCKED_RF", not "OBSERVATIUON".
- (c) If IFO reaches "PRFPMI_LSC_LOCKED_RF" state, wait until the TMSXY power seem to be maximized.
- (d) If you judge TMSXY power is around max, push "OBSERVATION".
- note: OMC hand off (PRFPMI_LSC_LOCKED) still has unstability, and tends to fail. We are still tweeking now.
- (e) IF IFO reaches "OBSERVATION", ADS for ETMs will be off, and BPC will be ON.
- Good oplev values will be recorded every 10 seconds. So if IFO unlocks, almost mirrors alignment will be kept according to the previous good oplev values. In this sense, SAL alignment will be the last last method to recover the IFO locking to recover IFO locking because IFO locking itself has a function to find a good alignment automatically. SAL has some amount of misalignment because it is done by human judge.
- LOCK_LSC guardian Process: Assuming from "DOWN" state
(2) SAF/FCL work is scheduled in the morning
(3) PEM work is scheduled in the morning
(4) CAL work for pre-observation will be done in this morning
(5) ASC will be tried until 16:00 after CAL work. Optical setting for ASC on the AS table was recovered yesterday.
(6) Observation will start at 17:00
