 * Activity report for week of 12/19
  * Hirata-san made, and Fabian and Mark checked, drawings and parts/fastener lists for the SRM/PRM order and various others: [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5964| D1605964]], [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5965| D1605965]], [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5956| D1605956]], [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5963| D1605963]], [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5977|D1605977]], etc.
  * 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) ===
==== Past week report ====
At Kamioka (Mark, Fabian, Enzo, Hirata-san):
 * Hirata-san did an inventory of SR and other parts at Kamioka.
 * Mark and Enzo finalized the geometry matrices for the IP, entered them in MEDM and updated the safe.snap.
 * Mark, Enzo and Fabian worked with Izumi-san et al. to align the BS. We got the +Y beam fairly close to aligned (to the second gate valve, near IY).

==== Plan for week of 10/30 ====

Kamioka: Mark and Enzo
 * Continue alignment of BS.
 * Realign OL.
 * Work on servos.

Mitaka: Fabian and Hirata-san
 * SR procurement.
 * New PI GAS FR design.
 * BS LBB ballast mass design.
 * SR cable lamp design.
