Type B Past Week Summary
- Mark and Hirata-san at Mitaka
  - Gathered parts for cable making.
- Mark and Hirata-san at Kamioka:
  - Replaced the floor panels that had been taken from the PR2 area (filling in the hole in the floor) and found/installed two new panels to act as bridges near the BS assembly frame.
  - Installed two more LPCDs and the stepper motor driver in the PR2 rack.
  - Ran cables from the rack to the second and third sat amps (for the IRM OSEMs).
  - Added a second DIO card in the rack and connected it to the BIO inputs and outputs of the new LPCDs.
  - Started making extension cables for RM-H2 and -H3 OSEMs but gave up due to complicated grounding arrangement.
  - Washed four 40-cm D-Sub-9 ribbon cables to use as temporary extensions (maybe also for H1/H4).
  - Added extension to the IM pico cable for the BF yaw pico.
  - Made LVDT adapter cable.
- Mark worked on schedule.

 Line 6:
-  * Fabian worked on IM and dummy BS assembly: [[https://photos.google.com/share/AF1QipMNVSExyP3TuyhK4s_VD-ARDlNoCPCf13ZDbHUlwOw14AKgj4XUe0vYg27dQ12icQ?key=SjJ0dXJ1bjN2OGVCN3d6RnoySEtFSjVJUmVwSlZR|photos1]], [[https://photos.google.com/share/AF1QipPQdoB5vYN1VcD32TkA4QSGldODvKRwiT5h-m122ahSpWmFyyrO5MX-9ajL1LeRIg?key=VFFuUVktcEtlMURQUldhZUlRcGFhbzNDeU5IN3NB|photos2]]
   * A hole in a picomotor holder was too small. ATC staff solved this isue quickly and Hirata-san cleaned the piece.
   * Some ballast discs for the dummy optic were dirty (seen by visual inspection). Hirata-san cleaned them.
   * Some arrows were cleaned from the mirrors for the dummy optic.
  * Hirata-san worked on checking Mirapro's assembly frame design - some minor issues with rail system found.
  * Hirata-san measured another filter.
  * Hirata-san washed a large batch of parts.
  * All parts for gluing of dummy BS are in hand. We arranged with Tatsumi-san to glue magnets at Mitaka on 6/6, glue flags at Kashiwa on 6/8, and inspect bonds and bring dummy BS back to Mitaka 6/13.
  * Mark worked on solutions to allow a [[http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/VIS/TypeB/dummyBS|larger mirror on dummy BS]]. After discussions with Simon and Akutsu-san we decided to go with a stainless steel plate solution. The gluing can go ahead and we can attach the plates later.
  * Mark worked on list of items for purchase in FY2016.
  * Mark worked more on [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235|E1504235 BS Assembly Procedure]] ([[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|Draft on OneDrive]])
