Summary of this week
- Height adsustment: Target is ITMY 6mm upper, ITMX 5mm lower.
- One of the stepping motor did not work. It seems current problem. It will be checked today.
- ITMY adjustment was done. ITMX height changed ~2mm.
- ETMY will be used for mass feed back.
- ETMY has high power coil driver now.
- Matrix diagonalization for ETMY seems to be much smoother than ITMY. Not sure the reason but ITMY seems to have more coupling.
- Next meeting: 5/21.
