1. Report of work of the last week and plan of work
- Alignment, ETMY: Izumi
- Mirror motion has been suppressed to ~2urad. Requirement is 1urad.
- Beam is checked almost every night.
- MIF: Izumi
- k1bs, k1imc will be connected by Dolphin. ETMs are connected to k1imc by RFM.
- CAL: Yamamoto, Yokozawa
- Started using IMC as training of calibration.
- Simple calibration will be implemented.
- X end PD is removed at 3/27 today.
- Started using IMC as training of calibration.
- ETMX:
- Connection between Type A and Cryopayload is done. Cabling is done.
- Height somehow changed from the last week to this week. We are fixing it, but it seems to change daily.
- Alignment will be roughly adjusted today, and first contact will be removed today.
- Circuits and connection to digital system are done. We started matrix tuning.
