 * 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.

=== IMMT (Ohishi) ===

 *Schedule
  * Most of the parts will be assembled and delivered to Kamioka on 28th Dec.
    (I will be taking winter holiday on 28th but I think I can chek it on 30th 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.
  * Hanging and installation will start from 4th January.
  * Two people from FCL are coming for hanging and installation till 12th January.

 * Mirror
  * Need to contacted with Hirose-san about the time when the mirrors are prepared.
   * 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.
 * 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
  * Dropbox.

 * Remaining parts status
  * PZT holder: ask FCL to make quotation.
  * coil holders: drawings exist. need to check before ordering.
  * D-sub holders; We had two 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.

 * Place for hanging:
  * Unfortunately I could not have find breadboard 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.
    (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).
