ALS Meeting on 2016/7/28 15:00 - 16:00
eZuce: http://srn.ezuce.com/joinSRN?meeting=M2MvMB292lD2DD9D9sDM92
Participants: Michimura, Aso, Enomoto, Nakano, Matsushima, Kambara, Doi, Moriwaki
Minutes
Default configuration for ALS is Tasumi/Arai/Aso configuration (see JGW-T1605353)
- We may have to put wideband EOM for IR beat to increase UGF and DC gain for PLL
- We may have to use CARM/DARM basis instead of XARM/YARM basis
NoiseBudget modeling needs to be done soon [Kambara]
Kambara will stay at Hongo for ~1week in August for a boot camp
- Start with a simpler model (e.g. just PLL only)
- Prometheus lasers will be put on PSL table to keep them clean
PSL layout and space should to be checked [Nakano]
EOM layout is Layout 3 in JGW-D1503189, so we can save space
Agenda
Decide default configuration for ALS JGW-T1605353
- Four candidates: aLIGO-like, simplified aLIGO, Tatsumi/Arai/Aso, or hybrid?
- Noise study will be done by Kambara after deciding the default configuration to start with
- Where to put Prometheus?
- Schedule?
- Possibility of installing GreenX earlier for TMS alignment?
- BS green reflectivity 99.40% for s-pol, 97.85% for p-pol
- Possibility of installing GreenX earlier for TMS alignment?
