Report of work
- X arm: Cause of build up issue was tuned out that calm servo was broken. Transmitted light became stable with another circuit.
- OMC: REFL port was consistent with that transmitted light had only 10%.
- It means no significant loss inside cavity.
- Still cause of 10% is not so sure. It could be mode matching.
- CAL: MICH calibration is done. High frequency looks petty flat, ADC noise? Needs check whitening on.
- PRM misaligned state did now work. It was tripped.
Work plan
- SRM needs some tuning, but probably OMC work has higher priority.
