= VIS special meeting on iKAGRA ETM and PR2 =
2016/1/6 14:00 - 15:45

Participants: Fabian, Tatsumi, Suzuki, Raffaele, Shoda, Takahashi, Tomaru, Aso, Mark, Akutsu, Fujii

== Agenda Items ==
 * Proposed plans (Aso)
  * [[attachment:CLIO-LISM-TAMA-KAGRA3000.pdf|Slides]]
  * Two descoping options are proposed
   * Use TAMA PRM with TAMA suspension as iKAGRA ETMs
   * Use fixed PR2
 * TAMA suspension status (Takahashi)
  * There exist 5 TM type suspensions in TAMA
  * Two of them have coils, others not.
  * Two suspensions with coils will be used for the filter cavity experiment
  * We need to make coils and associated parts
  * Some of the suspensions were stored in the air for a long time. We need to clean them first.
  * Tatsumi-san already got a quotation for coil bobins: delivery date 1/25
  * We can use D-sub instead of BNC, so that we can also use in-vac cables prepared for ETMs.
  * One of the TAMA PRMs is used for the filter cavity experiment. If we use this mirror, they need something instead -> LISM mirror (ask Ohashi-san)

== Conclusions ==
 * VIS team agrees to the two descoping plans proposed by SEO
 * ETM
  * NAOJ will take care of the preparation of the TAMA suspensions back to the original state. The rest of the installation work should be led by other people (e.g. Uchiyama-san). Aso will consult with SEO about this responsibility separation.
  * The following items are identified as the NAOJ tasks for the suspension preparation
   * Check the current status
   * Wash existing parts
   * Order missing parts
   * Coil winding
   * Send parts to Kamioka
   * Assemble the suspensions at Kamioka
  * The task assignment was discussed between Aso and Takahashi. They will contact people to get their agreement. Then the task assignment will be announced soon.
  * The filter cavity experiment needs a replacement mirror for the PRM. Aso will ask Ohashi-san about the LISM mirror.
 * PR2
  * The preparation and installation of the fixed mirror will not be done by the VIS people.
  * We need to consider how to effectively use the released man power for the preparation of bKAGRA suspensions -> to be discussed at the regular VIS meeting.
  * We need to secure and cover up the current PR2 assembly set up (Mark, Fabian)
