Report of work (*:responsible person)
- COM: IR beam reached at Y end
- We checked Y-end PDA
- Green beam for X arm was used for rough alignment of BS to center at ITMY
- Then IR beam hit the Y end.
- Type A:
- IP position of ITMY is somehow OK, but stepping motor of BF or is not working well.
- IP of ETMY is locked yesterday.
- TYPE B: GEO phone amp was replaced and it seems to be fine. We need a little more time to replace other GEO phone.
- MIR: HR of SRM cleaning is going on yesterday and today, HR of SR3 is the next.
- DGS: RFM network is available for both X and Y arm.
- CAM: k1cam0 was recovered.
- OMC: It was found that the beam is blocked by Type C OSEM. We need some modifications at the frame.
Work plan (*:responsible person)
- COM: Alignment of ITMY today.
- Type A: Releasing ETMY lock.
