Detailed task list of PCal is listed here.
X-end PCal
- TxPD1 repairing
- THS4631 seems broken
- Asked Bin-Hua to bring parts.
- OFS2 closed loop functionality repairing
- Relay is suspected. Will confirm using tester.
- Asked Bin-Hua to bring parts.
- Interlock equipment
- Switch is equipped to modules.
- Connector between chassis and laser system is repaired.
- Check DAC input between MEDM and actual
- Unstable D-sub connection at Tx module
- Some connectors are dead.
- Cable arrangement
- Laser remote control
- PC will be setup.
- Same script as in Y-end may be applicable.
- BPM test
- Picomoter setting
- Periscope install
- Equip picomoters to the mirror
- Wall between duct and modules
- Ordered. Will arrive Kamioka on 9/10.
- Set duct and wall.
- Green laser preparation
- Power supplies are OK.
- Waiting for new post.
- Rx module alignment
- TCam has to come back.
- PC has to be re-installed.
- AOM current
- Sometimes over 0.5 V ?
- Stray light
- Put dumpers
- Borrowing 2 from Toyama univ. They has to be returned on 9/19 or 20.
- Put dumpers
- WSK measurement
- Alignment of the last 2 mirrors (Accidentally moved)
- Modification is required from LIGO's procedure.
- Code for WSK measurement analysis
- To be delivered on 9/19 or 20.
- May have to prepare voltage calibrator to calibrate readout by DGS.
- DAC noise problem
- With DAC cable, very large noise and offset are observed. It may be difficult to set working point.
- Take care about grounding
- AOM response measurement

- Excitation noise measurement
- Peak stability test
- Shot noise
- Offset input noise
- Noise model
- OFS upgrade
- Preparation for X-arm commissioning calibration line injection
- Initial laser power just after turned on seems too small ?
- Operation tool preparation
