Summary Report
Type-A
Type-B
- SR2 mid-size baffles: Hirata-san and Yano-san successfully did a trial installation, including the balancing of the suspended lower breadboard.
- SR3 oplev:
- I recovered suspension and oplev alignment: all stages were set close to their setpoints and the beam went through the center of the lens.
- I set the lens in the optimum position with respect to the lens using a quantitative method.
- I calibrated the QPD output in terms of displacement.
SR3 control: Terrence is working on it. Rough plan and schedule here
- Calibration factors and sensing matrices of the optical lever were implemented.
- I haven't diagonalize the oplev, but sanity checks show very little cross-couplings. Might do diagonalization today or tomorrow.
- I measured all transfer functions and will do modeling soon.
- After that I will construct all control filters for SR3.
Type-Bp
In PR2, After a lot of preparation, they installed the mid-size baffles. The green laser passes through without problems.
