Agenda/Minutes of the VIS Meeting on 2016/6/24
2016/6/24 13:30 - 15:00 @ Room 210
Participants:
Progress report
Type-A (Takahashi)
- Simulation
Deadline is the end of June (Okutomi)
5 blades for BF -> "The filters in Virgo are different from the GAS filters (no compression). 3 + 2 combination is no problem." (by E. Majorana)
Type-B (Mark)
- Put a report here
Type-Bp (Shoda)
Designed the additional masses for the IM JGWdoc(Shoda)
Created the 3D model of the vacuum tank with the PR suspensions also for PR2, 3, and M. Sectional View of PRs(Shoda)
- Checked if the suspension parts clip any beams. Found the POX and POY beams are clipped at the RM. (Shoda)
Ckecked also the OpLev beam path inside the chamber except for PR2. Found that we cannot have the OpLev beam spot at the center of the PR3 optic. SVN(Shoda)
Summarized the information of iKAGRA PR3 measurement. Report(Fujii)
- Design for the modification of the optical bench suspension points is on going. (Shoda)
- We need the additional machining at the intermediate stage of the optical bench.
- Design for the installation jigs for the optical bench is on going. (Shoda)
- Detailed simulation for the modified Type-Bp is on going. (Fujii)
IMMT (Ohishi)
- Put a report here
Watchdog system (Tanaka)
I'm working on experiment for stability of PhotoMos Relay.
- (I will be reported at the next meeting(Maybe..).
Safety
- Any issue ?
Issues
- LVDT for BF damping (Shoda, Raffaele)
- Will have a meeting with Virgo on 6/27 from 4PM
- Available size around the BFs (Shoda, Sato)
- Length to pitch coupling simulation (Okutomi)
- Dummy payloads for Type-A (Takahashi, Aso)
- Dummy payload interferometer: unlikely to happen
- Need to think about how to test the Type-A performance without Michelson.
