Report of work
- COM: Finesse of Yarm was ~1200 with 60K of ITMY that is a bit lower than expected value even it was estimated by 10% lower ITM reflectivity.
- CRY: Temperature of ITMY will go lower from above results to distinguish ITMY contamination effect.
- CRY: Cooler for shield for all 4 test mass, and cooler for payload for ITMY and ITMX and ETMX are working.
Work plan
- Type B: Needs tuning for BS SR3.
- Type A: RT model was separated to two parts for ETMX and ITMX. It needs more time today.
