Agenda/Minutes of the VIS Meeting on 2016/9/2
2016/9/2 13:30 - @ Room 210
Participants: Mark, Takahashi, Ohishi, Aso, Hirata, Okutomi, Sato, Tanaka, Ishizaki, Fabian, Shoda, Raffaele
Progress report
Type-A (Takahashi)
- Top chamber: Installation and leak test will be postponed to January due to delay of cooling test of the cryostat.
- EQ stop, release sensor, dummy payload: Procurement is in the bidding process. Open bidding is on 13th September.
- BF damper: Assembling the LVDT prototype.
- Maraging wire: Stress concentration around the head was pointed out by CRY. Now investigationg.
Type-B (Mark)
- Put a report her
Type-Bp (Shoda)
- Type-Bp modification
- Saito-san made some updates around the LVDT coils. Shoda is implimenting them into the 3D CAD model.
- Obuchi-san provided the result of the structure analysis. Shoda will gather the information and write the design document.
- Saito-san is asking the cost estimate to Techno-port and still waiting for the reply. We asked him to ask the cost estimate to another company.
- Shoda is preparing the specification sheets for the ordering.
- We are planing to have the final design reciew from 12 - 14th September.
- Additional ordering for PRs.

- additional masses for BF: Shoda is making the model.
- IM flags: Hirata-san will make the drawing for the additional machinig.
- TM flags: Discussion is ongoing with Aso-san, Mark, and Hirata-san. (Old design parts will be ordered together with BF modification parts just in case.)
- 1st wire breakers: will be ordered with BF modification parts
- 2nd wire breakers: will be ordered with BF modification parts
- the correts for the hexagon cable clamps: the CAD model of the maraging rod is wrong. Re-design will be done by Hirata-san.

- Assembly frame
- Design is almost fixed: shown via Seevogh
- Optical bench
- Installation jigs: shown via Seevogh
- Adapters: shown via Seevogh
- wires: shown via Seevogh (the hook analysis is necessary?)
- missing hooks: shown via Seevogh
- Shoda is preparing the specification sheets for the ordering (together with the assembly frame).
- Washing
- EQ stop: 3sets are in Akeno, un-washed. Takahashi-san will order the washing.
- OB-IM, OB-MD: 3sets are not ordered yet. Takahashi-san will order them.

IMMT (Ohishi)
- Measured location of things in IFI and IMMT chamber with Kasuya-san on 23-24th Aug.
- It smelled bad (musty) outflow air from the vacuum chamber.
- Consider to install IMMT2 suspension from the Top flange of the chamber.
- Discussing with Somiya-san, Hirose-san and Kawamura-san.
- Kitazawa-san (Toyama Univ.) is coming to help coupling measurement of the small OSEMs for IMMT.
- 3D2D drawings of current IMMT suspension almost completed.
- Next week, MCF chamber will be opened.
