 * Type B Past Week Summary
  * Mark, Fabian and Hirata-san cleaned glue off the dummy BS, attached Akutsu-san's new SS mirror plates, reglued the flags and prisms, and removed the gluing hardware, so the dummy BS is ready for shipping. Tatsumi-san's refinements to the tooling (especially the new flag holders) worked very smoothly. We were more generous with the glue and much more careful with the alignment of the prisms to the barrel, both during rehearsal and the final gluing.
  * Mark wrote up the gluing procedure as a new document [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5505| E1605505]]. (The original plan was to do an addendum to Tatsumi-san's PR gluing procedure JGW-E1504248, but there was too much material.)
  * Hirata-san organized with Takahashi-san to get the BS payload masses shipped to Kamioka. They will go in an air-ride truck on Wed 8/17 together with a load of Type A stuff, and will arrive early on Thu 8/17.
  * Hirata-san measured another standard filter.
  * Fabian worked on the payload assembly procedure.
  * Komori-kun, Kuwahara-kun and Akutsu-san calibrated an initial batch of 7 wide-mouthed OSEMs. They will be shipped to Kamioka on Friday.
 
 * Type B ongoing issues
  * OSEMs
   * First batch of 7 ready for shipping.
  * Longer cables for BF->PI and SF->PI.
   * Connectors RECEIVED, cables being made.
  * Lower breadboard stuff
   * Installation to be incorporated into the procedure document. Mark/Takahashi to discuss.
  * Documents
   * BS Assembly Procedure [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235| E1504235]], [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|E1504235 draft]]
 * To-do list during Mark's vacation
  * Weigh IM/RM/IRM (Fabian, Hirata) - DONE
   * New trim mass - ORDERED.
  * Pack/ship IM/RM/IRM to Kamioka (Hirata/Fabian) - READY TO SHIP.
  * Analyze geophone data (Fabian/Shoda) - DONE.
  * Remove glue from dummy BS face (Fabian) - DONE.
  * Reglue flags and prisms (Tatsumi, Fabian) - DONE.
  * Clean wire for BS and RM (Hirata) - DONE
  * Get new winch parts for new wire diameters - ORDERED, expected 8/5.
  * Do fit/function test of winches (Fabian/Hirata) - fit test DONE, function test from 8/8
  * Ship winches to Kamioka (Hirata/Fabian)
  * Work on BS simulation (Fabian)
  * Do Inventor assembly for SR2 in chamber and on assembly frame (Hirata) - ONGOING.
  * Write more of payload assembly procedure (Fabian) - ONGOING
  * Write more of main assembly procedure (Mark) - ONGOING
 * Longer term to-do list
  * Do BS Simulink model (Mark, Kokeyama)
  * Do 2D drawings of SR2 parts (Hirata)
  * Redesign SRx IM wire clamps for larger prisms, remachined RMs
  * Order SRM/PRM parts (Hirata/Shoda)
  * Order SRx fasteners (Hirata)
=== Type B (Mark) ===
==== Report for Golden Week ====
 * Mark monitored vent and pumpdown, and worked on vistools.py.

==== Report for the week of 5/6 ====
 * Lucia and Terrence got the blending working for the IP LVDTs and geophones.
 * Terrence and Mark modified the models and MEDM screens to add a new IP block, IDAMP, for damping using the blended signal with inertial information, and a new DAMPMODE block for ramping smoothly between IDAMP and the old DAMP.
 * Mark worked on vistools.py, improving the support for cdsMuxMatrix blocks (e.g., OSEM2EUL) and adding support for cdsRampMuxMatrix blocks (e.g., the newly introduced DAMPMODE). He also created two sets of unit tests, unittest.py and unittest.sh, for the two modes of use (as a Python module in other Python programs, and as a command-line utility in bash).

==== Report for week of 5/13 ====

==== Vacation/Travel Info ====
 * Terrence's next visit from 4/18 to 7/27.
 * Mark's US vacation from 5/22 to 6/11.
 * Mark's final day 6/28.
