 * Type B Past Week Summary
  * Fabian, Mark, Yokogawa-kun and Kuwahara-kun did BS installation at Kamioka:
   * Calculated BS pitch correction ([[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5630|JGW-T1605630]])
   * Hung dummy optic and set pitch.
   * Prepared RM.
   * Placed vacuum feedthroughs on assembly frame and cleaned D-Sub cables.
   * Decided position of BS rack with Miyakawa-san.
   * Measured maraging rods.
   * Placed safety rails, rearranged floor panels, cleaned new floor panels, and otherwise improved safety.
  * Hirata-san:
   * Made new 3D models of the maraging rods for PRx and SRx
   * Made new collet design for PRx and SRx.
   * Made new IM flag design for PRx and SRx.
   * Washed lots of Type A BF parts and OSEM parts.
   * Measure some BF part dimensions.
   * Pre-assembled parts for BFs.
 * Type B ongoing issues
 * Longer term to-do list
  * Do Inventor assembly for SR2 in chamber and on assembly frame (Hirata) - NEARLY DONE.
   * Part "disk security" top has to be modified - screw positions do not match.
  * Write more of payload assembly procedure (Fabian) - ONGOING
  * Write more of 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]] (Mark) - ONGOING
  * Lower breadboard installation to be incorporated into the procedure document.
  * Work on BS simulation (Fabian)
  * 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 the week of 4/1 ====
 * Support of Type Bp
  * Hirata-san procured the jigs for PRs and Takahashi-san tested one at TAMA.
  * Hirata-san cleaned up the flags for PR2 and Mark did the one for PRM.
  * Fabian helped Fujii-kun and Takashashi-san to reglue the flags.
 * Mark did a lot of maintenance on the MEDM screens:
  * Made the name of the suspension more obvious (no yellow text!).
  * Added rack temperature indicators.
  * Fixed the labels in the ADC screen (to reflect the LEN OL moving from ADC#0 to #1).
  * Fixed broken links.
  * Committed files to the SVN.
 * Mark did maintenance on the Guardian to make it give more helpful messages in the TRIGGER state. Formerly it only checked the user model watchdog and the coil driver watchdog, not the DACKILL, and gave the same generic notification for both. Now it checks all three and tells the user which need attention.
 * Mark tidied up the cables in the SR2 rack and returned a large pile of no-longer-used cables to the tent.
 * Mark started a !HealthCheck page on the Operation Manual wiki.
Fabian and Mark
==== Plan for week of 4/8 ====
 * Mark, Fabian at Kamioka Mon-Fri.
 * Help with Type Bp.
 * Health checks on Type B.
 * Monitor pumpdown.
 * Work on Type B paper.
 * Modify RT models and/or Guardian to revert to the SAFE state under control in all but the most extreme emergency situations (rather than suddenly shutting off all output).
 * Tidy up.
  * Gather and clean tools.
  * Gather and organize unused parts and fasteners.
