Minutes of ISC Meeting on 2015/7/27

14:00 - 15:00 on SeeVogh

Participants: Aso, Miyakawa, Kokeyama, Somiya, Arai, H. Yamamoto, Ueda, Nakano, Akutsu, Michimura

Agenda

iKAGRA commissioning:
- Need to be prepared befoe starting the commissioning.
- We should make a noise budget model beforehand.
- Also we should perform necessary measurements (such as PD dark noise) as much as possible beforehand.
IBF:
- Only considering the power reduction of the RFSB is not enough. We should estimate the actual impacts on the loop noise, ASC, etc.
- We should check with Hirose-san how much assymmetry between X and Y arms were introduced with his simulations.
- We now have more mirror maps including BS. Should be able to perform more realistic simulations.
- There was a bug in the SIS code. Should re-run the simulations.
- Ask Hirose-san for the mirror maps.
OMC requirements
- KAGRA cannot remove the power term of the substrate transmition by a ring heater. Should expect more HOM power from the power term.
OMC suspensions
- Talking with UWA. Also NIKHEF is a possibility.
Beam dumpers
- We should be prepared for the beam dumps when some of the mirrors are mis-aligned during the alignment works
bKAGRA commissioning
- Aso will send some slides. When to go to cryogenic ?

Aso will talk with the leader of each research group about their efforts for the ISC tasks.
Aso will personally contact people for task assignment
JANGO would like to be assigned tasks in big chunks
