Discussion
- Results of finesse measurement looks a bit too high. Needs estimation of loss inside cavity for Yarm.
- We should keep finesse measurement for going back the cooling down ITMY.
- For DRMI preparations, optics, circuit, cabling, control models are almost ready.
- Type A control test should be done during DRMI.
- Type B and A needs some IFO as sensor.
- Write manual if you experienced something.
- CAL: MICH and DRMI calibration model is ready.
- Remote work should be managed by calling to control room or sending email to gokagra.
- Smooth transition for when watch dog is engaged has been implemented to Type B. It should be implemented to Type A.
When? -> Maybe tomorrow morning during maintenance time or the next week during DRMI.
- Engineering run:
- IMC is the first candidate which will be used for run. This is because Guardian is ready for only IMC, not for Michelson or X arm.
Others
- Next meeting: 5/28.
