Progress report
Type-A
Past week report
* For the 150mHz-ish mode damping
- sensor correction for IP, i.e., seismic signal subtraction system, was implemented to all the type-A suspensions.
* For inertial damping performance test > By Lucia
* length-oplev calibration with green lock
log: 9989
- 1st trial. The values are *NOT* installed since we could not guarantee if we were observing TML motion not TMY motion. It looks they are not terrible values, compared to ground motion though.
* F3-GAS of EY: looks stacked again
log at 2019 Aug. 15th, when it was stacked: 9990
log at 2019 Aug. 15th, when it was free: 9293
- The difference between the above is like about 405um (it went to lower position.), based on GAS_LVDTINF_OUT channel.
Plan for coming weeks
* Guardian stuff
- utilize the TMY to BFY loop again, etc.
* RTmodel modification
- open paths from TM to IPL, BFL to IPL
