 * Type B Past Week Summary
  * 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]])		 === Type B (Mark) ===
==== Report for week of 1/29 ====
 * We moved the top filter intended for SR2 (#1) into the SR3 cleanbooth.
 * Unfortunately we noticed one of the blades had many small X-shaped stress fractures on the top surface (klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=4058|4058]]).
 * We moved the top filter entered for SR3 (#3) into the SRM cleanbooth and inspected the blades. Two had one smallish stress fracture each and one had a huge fracture and looks close to failing (klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=4061|4061]]).
 * We referred the BS OL.
 * We removed the BS tank lid and inspected the BS top filter blades. They seemed fine.
 * Hirata-san received and washed some ferromagnetic disks for IM flags and other small parts.
 * Hirata-san moved the BF with the tilted keystone (#1) out of the cleanbooth in preparation for rebuilding.
 * Hirata-san
 * Fabian measured the gain of the ADC system (homework from the Commissioning Workshop).
