Detailed task list of PCal is listed here.
X-end PCal
Urgent
- RxPD1 repairing
- 2 ICs seems broken. ICs have arrived at Kamioka.
- 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
- 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 ?
