Detailed task list of PCal is listed here.

X-end PCal

Urgent

  • RxPD1 repairing
    • Repaired but not tested.
  • OFS2 closed loop functionality repairing
    • Register is missing. To be delivered.
  • Interlock repairing

2nd-urgent

  • Laser remote control
    • Setup done. LAN cable should be replaced to shorter one.
  • Stray light
    • Put dumpers

~10/20 first test to inject PCal laser to the X-end test mass

  • Rx module alignment
    • After vacuuming and ETMX alignment by commissioning team.
  • AOM response measurement
    • Check working point is consistent to that in KEK
  • OL/CL TF measurement
  • WSK measurement
    • Modification is required from LIGO's procedure.
    • Code for WSK measurement analysis
    • It is at Toyama Univ.
    • May have to prepare voltage calibrator to calibrate readout by DGS.

~X-arm commissioning line injection

  • BPM test
    • Picomoter setting
  • Preparation for X-arm commissioning calibration line injection

~O3

  • RPN measurement
  • Laser noise measurement
  • Harmonics noise measurement
  • VGA noise measurement
  • Excitation noise measurement
  • Peak stability test
  • Shot noise
  • Offset input noise
  • Noise model
  • Unstable D-sub connection at Tx module
    • Some connectors are dead.
  • Cable arrangement
