Participants: (eZuce meeting)

2017/7/3 14:00 - 15:00

Agenda

PSL EOM Layout re-consideration [Enomoto] (JGW-T1706748)
- Delay-line length decided to be 2.66 m (instead of 8.88 m)
- Modulation phase between f1 AM and PM is always aligned (we need this to be aligned)
- Modulation index needed at each EOM is less than measured maximum index by Uehera (JGW-T1605611)
- Optickle simulation by Kohei Yamamoto
  - simulation on imperfections (MZ arm asymmetry, MZ lock, EOM phase difference control etc.)
  - start with hand calculation, simple setups, and then to full IFO simulation
  - meeting with him on June 6.
- Requirement on carrier power loss?
OFI and OMC status? [Somiya]
- look for OFI with larger aperture [Somiya]
- output optics task sharing status?
- OMC baseplate issue?
- design review on June 26
Actuator noise modeling [Michimura,Miyamoto] (JGW-T1503453)
- Updated magnet size for cryopayload marionette (ActuatorDesign wiki)
- Needs to implement frequency noise, but FSS modeling with ALS is complicated [student!]
- Needs to update lock acquisition section (see ISC Meeting minutes 20170410) [Michimura]
bKAGRA Phase 1 initial alignment / commissioning plan [Michimura]: JGW-T1605692
- updated based on current schedule
  - ETMX and ETMY cryopayload installation almost at the same time
  - MICH lock at room temperature before cooling down (instead of cooling down ETMY first)
  - AS cannot be used for room temperature MICH lock (SR3 not ready)
  - SR2 won't be ready by the end of March 2018
