FPC Meeting on 2019/02/05 15:00 - 16:10 (JST)
Participants: Eleonora Capocasa, Kentaro Komori, Matteo Leonardi, Yuta Michimura, Atsushi Nishizawa, Kentaro Somiya, SH
Zoom meeting(2): https://zoom.us/j/6676627462
- Next meeting will be around end/Feb (doodle poll will be circulated).
Action Items
Re-organize the section (SH) => Done
- Collecting the science part (Coordinated by Nishizawa, ... )
- Fill-up the remaining part in Technology Survey coordinated by
- Matteo : squeezing and filter cavity
- Michimura : Low frequency related
- Haino : Cryogenic and mirrors based on inputs
- KAGRA sensitivity code update and merging with GWINC and other codes
- Review of KAGRA code with GWINC (SH - with some help by others - also for the OSP issues)
- Review and check the squeezing parts (Matteo, Eleonora, ...)
- Talks
- KIW5 slides to be circulated in FPC (SH), talk request already submitted to CPC
- LVC meeting, talk request already submitted to CPC
Minutes
Frequency dependent squeezing in KAGRA by Eleonora and Matteo
- ~100m scale filter cavity seems necessary but not much improvement above ~300m
- Code unification (NAOJ-Matlab(Kwee paper), GWINC, KAGRA-Matlab) will be necessary to produce the "official" plots and discussions
- The first step of the white paper is to make some suggestions on the filter cavity (VS physics merits) and input to SEO for more practical consideration
- Michimura, Eleonora, SH will join from FPC
- SH will give FPC overview talk (slides to be circulated to FPC and CPC), Eleonora will give the FD-squeezing talk (chaired by Michimura)
- Listing-up possible collaboration works between KAGRA and ET and asking for their response (e.g. detailed PI calculation)
- Matteo commented that it is very good to get comments from LV
- SH contacted Brian Lantz and Stefan Hild and got encouragement. SH will submit a request to CPC
- White paper
- A bit of re-organization of sections
- Sections for (Current and new) noise sources and technology survey
- We should have up-to-date KAGRA Technical Design Report, TDR (either in white paper or in a separate document)
- The facility limitation should be discussed anyway in addition to KAGRA TDR
- Interface control documents exist but seem to be too old (2013
Agenda
- Current progress of the white paper
- Science still waiting; at least highlights can be shared/reminded inside FPC
- Survey of technologies in progress
- Squeezing and filter cavity (E. Capocasa)
- Facility limitations/subsystem summary (good contribution from Akutsu-san)
Talk from FPC (by Michimura-san or SH) at KIW5
Talk from FPC at LVC meeting
- Positive response from the organizer; possible talk either at Joint Instrument Science session on Tuesday afternoon or the Plenary session on Thursday)
