Progress report
Type-A (Takahashi)
- Installation: The first transportation to Y-end for Type-A items is scheduled on 7-9th. The second one is scheduled in early January.
- Pre-isolator: Cable connection and check were finished. Two sets have been shipped on 1st.
- EQ stop, release sensor, dummy payload: The parts remained will be delivered on 12th.
- BF damper: The production is on going.
- Maraging wire: Ordered. The first set will be delivered by 20th January.
- Tooling for installation: The hoist tool was ordered.
Type B (Mark)
- Mark worked on task lists and schedule.
Mark worked on an update of the BS Electronic Items doc (E1505111) and started a SRx Electronics Items doc (E1605886).
- Mark did a summary spreadsheet of Takahashi-san's cable orders to see what needed to be ordered immediately (new BS TM OSEM cables; geophone adapters) and later (for SRx).
Mark worked on an update of the In-Vacuum Cable doc (E1503901), including information on final lengths that Fabian and Hirata-san had decided when making adapter cables.
Mark considered an alternative cabling scheme for the geophones (with a different adapter cable to put the signals and power on different lines and a matching unscrambler) but ended up concluding that the existing design would probably be OK. See 00 Revised Geophone-v2.PDF.
- Fabian worked on a redesign of the EQ stops for the BS (2 of 4 screws under the RM are opposite large holes and there are no screws to restrain the RM front/back at either top or bottom).
- Hirata-san worked on PR/SR mirror box modifications with Shoda-san (on-going).
- Hirata-san partially assembled a bottom filter for use in fit tests of the PRx BF recoil mass.
Need to order geophones immediately (Takahashi
Type-Bp (Shoda)
- Installation preperation
Flag removing is postponed because we found that some of the parts are required to be re-manufactured.
- We will try again at 9th Dec.
- New assembly frame will be constructed on 12th and 13th Dec.
- Flag/Wire breaker glueing will be done on 15th and 16th Dec.
- Hopefully, the mirror will be sent to Kamioka on 19th and we can start hanging from 20th Dec. (19th is extended chief MTG.)
- Design
- For the installation of the main suspension chain, a clean chain block is ordered. Pararelly, removable jacks on the inner frame is being prepared.
- 3D design of the mirror box modification is almost done. 2D drawings have to be prepared.
- PR3 will be returned to Mitaka today. Need to transport it to Kashiwa.
IMMT (Ohishi)
- Schedule
- Most of the parts will be assembled and delivered to Kamioka on 28th Dec.
- Dec 20th:Processing completion
- Dec 21th-22th:Assembly
- Dec 26th :Optional extra day
- Dec 27th:Shipping
- It depends on the mirror and jig status, but I think the mirror will be hung
- without magnets/standoff for initial alignment scheduled in January (Need to be confirmed).
- Hanging and installation will start from 4th January.
- Two people from FCL are coming for hanging and installation till 12th January.
- Most of the parts will be assembled and delivered to Kamioka on 28th Dec.
- Mirror
- Need to contacted with Hirose-san:
- IMMT1:
- Ø: 99.77 mm; Thickness at thinnest point: 51.76 mm; Wedge: 2.45°
- IMMT2:
- Ø: 99.75 mm; Thickness at thinnest point: 52.93 mm; Wedge: 2.45°
- Thickness of the mirrors are 1.17mm different.
- IMMT1:
- Need to contacted with Hirose-san:
- Magnet and standoff fixture jig
- Plan to modify MC jig
- MC jig: perhaps still in Kashiwa.
- Need at least two new parts and two sims for different thickness of the mirror.
- Hanging jig
- Now in Mitaka. Will be delivered to Kamioka by Tatsumi-san.
- Drawings
- will be uploaded to dropbox.
- Remaining parts status
- PZT holder: asked FCL to make quotation.
- coil holders: drawings exist. need to check before ordering.
- D-sub holders; We had two holders but now one of it was used for MCo.
- Need to make another one.
- Hanging and Installation Procedure:
- Because it is difficult to install IMMT2 from side flange,
- we are planning to install IMMT2 from the top flange.
- Need discussion with Hirose-san about cleanliness control.
- IMMTs are not on the center line where crane moves.
- So perhaps we need to move IMMT by hand after we install it from the top flange.
- Prepare hanging and installation manual next week.
- Because it is difficult to install IMMT2 from side flange,
- Place for hanging:
- Unfortunately I could not have find breadboard(GIF) legs.
- Ask Kawamura-san if I can use small optical table that was used at MC recently replaced with larger optical bench.
- Cables:
- For initial alignment, planned in January, I think only Pico-motors will be necessary. (Need to be confirmed; Coils will not be used for initial alignment.)
- There already cables used when it was used for iKAGRA ETMs.
- Check the place where cables are now; flippers are in branch office.
- Check Flange
- Digital models
- Have not prepared yet.
- IMMT picomotor drivers are located in Mozumi now.
- Miyo-san said he already setup IP for IMMT drivers and will prepare network port in IOO rack next next week.
- Others
- Nippon Tungsten Company will give us sample of wires.
- Pushers: Ask MIF to prepare it.
- IMMT2 frame were modified to secure +/-1cm range for pico-motor.
- However, IMMT1 frame were not modified so the range is +/-5mm (originally).
