 * Activity report for week of 12/19
  * Mark and Fabian checked Hirata-san's drawings and parts/fastener lists for the SRM/PRM order and various other drawings.

  * Fabian designed a simple two-piece hold-down device to immobilize the SRx IMs during the optic and RM hanging. It avoids having to remachine all the IM support bars to allow for hold-down screws. The Type Bp team might also want to use it.
  * Aso-san and Mark discussed the [[KAGRA/Subgroups/VIS/VISMinutes20161216#BFIssue|BF issue]] from last week.
   * It was decided to ask Takahashi-san to take a look at the BF while he's at Kamioka this week.
   * It was decided to have the BS bottom filter moved to Mitaka for tuneup and adjustment as soon as possible in the new year.
  * Raffaele, Aso-san, Mark and Fabian discussed having much smaller/shorter BS and SR stub flags plus longer, coil-only OSEMs.
   * Aso-san volunteered to do the OSEM design.
   * Hirata-san made Pack'n'Go archives of the existing designs as a baseline for Aso-san.
  * Hirata-san searched for missing PR mirror box parts.
  * Miyakawa-san finished recabling the PR2 rack and got the real-time model running again. The model still needs lots of work, but it has the OSEM functionality needed for the next test-hang stage, plus Okutomi-san's improvements.		 === Type B (Mark) ===
==== Report for week of 4/9 ====
 * Mark glued prisms and magnet/standoff assemblies on the SR3. The SR3 needed to be raised in the box by 0.7 mm to make the prisms go on at the right height, which was done using M4 washers under the PEEK feet.
 * Mark glued ferromagnetic disks on the last 5 IM flags. This completes 2 sets, for SR3 and SRM.
 * Mark configured two pico motor drivers ordered by Takahashi-san as SR3-IM and SRM-BF.
 * Enzo and Kozu-kun finished preparing and calibrating the SF and BF for SR3 and almost entirely finished with those for SRM.
 * Hirata-san worked on building two IMs for SR3 and SRM. The SR3 one just needs to have flags attached and to be weighed; the SRM needs another few hours work.
 * Shoda-san worked on the design of the metal SRM, on the LBB ballast mass, and on the plans for testing the BS in bKAGRA Phase 1.
