Past week report
- The RM TF measurement is done. They seem to be OK.
- GAS calibration factor adjustment.
- One of the coil driver injected large noise into the LVDT sensor. Asked Kamiizumi-san to check it next week.
- We hanged the IM.
- It should be OK to use the HR surface for the pitch alignment. We hit the oplev bean on the 1st wire breaker to set it on the center line of the mirror.
- We found that IRM cannot be assembled with the IM tilted so that the pitch of mirror is as designed.
With the help of Takahashi-san, we moved the suspension wire on the HR side at the bottom of the mirror in order to shorten the effective suspension wire length. -> mirror tilt seems to be fixed.
- IRM is assembled. IM OSEM signals are now online.
Plan for coming weeks
- BF FR actuation check
- TF measurement of IM stage
