VIS Meeting on 2015/11/5
2015/11/5 After the NAOJ GWPO Meeting (14:00 - 17:00)
Kamioka NAOJ Room + SeeVogh
Participants: Shoda, Takahashi, Fujii, Ohishi, Michimura, Raffaele, Okutomi, Mark, Tatsumi, Akutsu, Manuel, Hirata, Fabian, Ishizaki, Aso
Schedule
- Schedule Plan (Aso)
- Control test: are the transfer function measurements necessary ?
- Remote measurement is a possibility.
Change "control test" -> "signal checking" (not including TF measurement)
- We need to come up with a way to make the working hour longer (two teams taking shifts ?)
PR
- Test Hanging Status (Shoda)
- Galled screws (Takahashi)
- Galled screw was cut.
- Another screws almost galled, but we were able to remove them.
- By using turn backles, we lifted the security interface plate horizontall and were able to put the screw without galling.
- Galled screws (Takahashi)
- Production of new EQ stop screws (Takahashi)
- Need to make new EQ stop rods because of the screw galling.
- We had 6 sets. Now we lost 1set. We need 4 sets for iKAGRA. No need to hurry up in producing them.
- Digital system (Shoda, Okutomi, Fujii)
- A simple model with only one filter is available
- Sattelite box and coil drivers are ready
- Need to check the OSEM (Tue)
Where to put the satellite box ? Grounding ? -> Mark
Digital system preparation (confirm that the model works) -> Okutomi
- Cleaning of the chamber (Okutomi)
Will consider to out source. Aso will talk with Saito-san.
- Cable status (Takahashi)
- 1st set will be delivered in the next Monday.
- 2nd set at the end of the next week
- Remaining ones in the following weeks.
Call for shift for cable checking ? Need to establish the checking procedure first. Then call for shift (Takahashi)
- Additional PR mirror box (Tatsumi)
- Order was placed.
- Delivery before 1st Dec.
- Production of additional PR winches (Akutsu)
- Ordered all the parts. Delivery before 1st Dec.
Assembly work needs to be scheduled
- PR Optical Bench (Akutsu)
- Ordered the required screws. Delivery in 10 days.
- Height adjustment will be done at the time as the preparation work for PR3 installation.
- RM compensation mass: do we have enough of them ? (Fabian)
- Having some problem with screw model in CAD (density was wrong). Hirata-san is fixing it.
We should order compensation masses with various thickness (Takahashi)
Lock nuts may have to be changed to cope with the changed length of the EQ stop screws. -> probably this is not so important.
- RM EQ stop screw position (Akutsu, Shoda)
- A stop screw will penetrate an opening in the RM.
Hirata-san will check if we can move the screw holes up or down to solve the problem.
- Next week (from 11/9) plan (Aso)
- Mechanical Assembly (Takahashi, Shoda, Mark, Fabian, Fujii)
- Mon: Put BF
- Tue: OSEM signal check
- Wed: Hang IM
- Thu - Fri: Assemble IMRM
- Digital system preparation (Okutomi): Try to run the simple model on the computer near the PR3
- Cleaning: discuss with Hirose-san, Nakano-kun to establish the procedure
- Travel plan
- Takahashi: Mon-Thu
- Shoda: full week
- Fujii: Wed - Fri.
- Okutomi: full week
- Fabian: Wed - Fri.

- Aso: Mitaka on Mon.
- Mechanical Assembly (Takahashi, Shoda, Mark, Fabian, Fujii)
BS
- BS Assembly Frame Design (Aso, Hirata)
We need to discuss the IM alignment mechanism for hanging frame part -> Change the scews to ball point ones: Takahashi-san already bought them.
- Since the frame is very tall, we need a step or intermediate height floor safe work. Mark will give us prefered height
-> Mark will send us the drawing with possible step heights.
- BS magnet size (Michimura)
- Recomendation from the special meeting: reduce the size of the magnet by a factor of 30.
- Paired magnets for reducing the magnetic field noise
IM magnet size: needs to be checked -> Shimoda, Michimura
- BS gluing jigs (Tatsumi)
- We haven't placed order yet. But the company has started some manufacturing.
- Can we wait 10 days for order until we have the thermal noise result ?
- Not enough crane height problem (Hirata, Saito)
- There seems to be some solution.
- Asked Saito-san to give us the plan.
- IP Base Clamp (Fabian)
Fabian will send a new version soon (by the end of the week)
- BS clean bag (Aso)
Will design it soon as the size of the assembly frame is almost fixed
Other
- Screw inventory (Ishizaki)
- Ishizaki-san came to Kamioka to make an inventory of the screws we have.
- Print out the inventory. Check when you use screws.
- PR suspension model checking (Hirata, Akutsu)
- EQ stop part is finished
- Started working on the payload part
- Watch dog system (Tanaka)
- Got a new document from Tanaka-san
- Clean suits (Aso)
- Asked Miyoki-san to order many
- ETM installation procedure (Takahashi)
Will have a discussion next week
- Magnetism of the OSEM screw (Akutsu)
Sekiguchi-kun pointed out a possible problem with magnetism of the screws around OSEM. -> Check with Sekiguchi-kun
- GAS blade inspection by Virgo (Takahashi)
- Waiting for more information (mostly shipping info) from Ando-san
