Summary Report

Type-A

  • Disassembled the footholds around the top chamber in EY.
  • Review of IY and EY.

Type-B

  • SR2 geophone calibration: I found an error in my script, and now I'm getting more reasonable results. See the klog.
  • In SR2, I calculated inter-calibration factors between geophones and LVDTs. See the klog for details.

Type-Bp

  • Measured the transfer functions of the PR suspensions.
  • We installed new cable clamp boards, and clamped the cables such that no connectors were hanging.
  • We installed the limit switches for the Traverser in PRM.
    • We still need to connect them to the drivers, but we don't have the drivers yet.
    • We should check the health of the cables we clamped on the new boards. We don't have a date to do this work yet.
    • We should decide a date to test the limit switches, but I guess that depends on when the drivers will become available.

Type-C

  • Installed the repaired high power coil driver to the OMMT1.
