 * Type B Past Week Summary, weeks of 9/19 and 9/26
  * Fabian, Mark and Kuwahara-kun did BS installation at Kamioka:
   * The BS clean booth was modified 9/20-21 to allow crane access. The area was fairly clean when Fabian inspected it on 9/26, but there were lots of metal flakes stuck to tape holding foil over the slit in the top of the clean bag.
   * Mark created a new Type B rtcds model and MEDM screens for the BS, adapting the TypeBb/PR3.
   * Mark and Kokeyama-san debugged the new model, fixing several issues.
   * Kuwahara-kun derived OSEM2EUL and EUL2OSEM matrices.
   * Mark set up OSEMINF filters using measured OSEM calibration data to return outputs in µm.
   * Mark took free-swing data on the TM stage to get the pendulum mode frequencies for comparison to the SUMCON model.
   * Mark and Fabian debugged the coil output to the OSEMs. (At first the coil drive was not giving output because it did not have BIO inputs and so was reading the test input, not the main input. And for a while output failed because of a loose cable to the sat amp.)
   * Mark took fixed-sine TFs to check the polarity of the coil-magnet combinations.
  * Hirata-san:
   * Finished 3D CAD of SRM in tanks (but some work was lost due to a hard disk crash).
   * Did 3D and 2D for new maraging rods, stub flags for PR/SR (ditto re hard disk).
   * Measured/tested Type A BF #8 and started assembling #9.
 * Longer term to-do list
  * Do Inventor assembly for SRx in chamber and on assembly frame (Hirata) - SR2/SR3 DONE, SRM ongoing.
   * 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) - TM/IM/BF level DONE
  * 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 week of 4/9 ====
 * We packed away the SRM SF and BF.
 * After several failed attempts with one secondary prism, Mark finished the SR3 prism/magnet gluing.
 * Tanioka-kun built two IRMs (less OSEMs).
 * Enzo built an RM.
 * Kozu-kun and Enzo calibrated one set of 6 IM OSEMs for SR3. (6 OSEMs for SRM remain to be done.)
 * Hirata-san aligned the assembly frame, installed the interface bars and IM ring, and installed the IM.
