Detailed task list of PCal is listed here.

X-end PCal

Urgent

  • TxPD1 repairing
    • Repaired. To be checked.
  • OFS2 closed loop functionality repairing
    • Relay is OK. Investigating the cause.
    • Asked Bin-Hua to bring relay.
  • DAC noise problem
    • With DAC cable, very large noise and offset are observed. It may be difficult to set working point.

2nd-urgent

  • DAC input bias between MEDM and actual
  • Laser remote control
    • Setup done. LAN cable should be replaced to shorter one.
  • Stray light
    • Put dumpers
      • Borrowing 2 from Toyama univ. They has to be returned on 9/19 or 20.

~9/11

  • Periscope install
    • Equip picomoters to the mirror

~10/3

  • Complete periscope install
  • Rx module alignment

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

  • 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
    • To be delivered on 9/19 or 20 to 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
  • OFS upgrade
  • Operation tool preparation

Bonus work

  • AOM current
    • Sometimes over 0.5 V ?
  • Take care about grounding
  • Initial laser power just after turned on seems too small ?

Pre-categorization

Y-end PCal

Laser power calibration setting in Toyama Univ.
