IMC Information
- Current IMC servo topology:
- Common mode servo board configuration:
- slow path to AOM???
- IMC sideband frequency: 13.78 MHz
- Measured IMC modulation depth: ~0.1 rad (measured??)
- Measured IMC finesse: 540 +/- 70
- Measured IMC length: 53.3 m
http://klog.icrr.u-tokyo.ac.jp/osl/?r=616 (Could be slightly different right now since we had re-installation work after this measurement)
- Measured IMC mode matching ratio: 86.2 %
https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/DocDB/ShowDocument?docid=5019 (Could be fairly different right now since we had re-installation work after this measurement)
- Measured MCe RoC: 37.33(9) m
- Measured AOM actuation efficiency: 5.064(7) MHz/V
- Measured MCe actuation efficiency: 6.9 um/V (any data for MCi and MCo?)
- Calibrated IMC WFS noise level, and some noise hunting:
- Accelerometer on the PSL table:

- (UPDATE SVN)
- Frequency stabilization servo modeling (design):
