Summary Report

Type-A

  • Implementation of the IP control with ACCs in IY.

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.
