VIS Meeting
Date: 2023/1/20 13:30-13:40
Participants: Takahashi, Fabian, Mitsuhashi, Tanaka, Aso
Summary Report
Type-A
- Implementation of the IP control with ACCs in IY.
- Adjusted the conditioning filters and made a sensing matrix to Euler direction (L, T, Y) for the ACC signals. We confirmed the signals of geophones and ACCs are consistent.
Type-B
- I calculated the expected performance of the sensor correction fitter, designed for SR3 F0 LVDT, in the BS. The performance is similar, although not as good because the LVDT has a lower sensitivity. Details are in the klog.
- Copied the filter into the BS, SR2 and PR3 filter banks, taking into account their respective intercalibration factors.

Schedule
- Type-A: IP control with ACCs.
- Type-B/Bp: F0 sensor correction characterization. This means, free-swing amplitude spectral density measurements and consistency comparison with expectations.
