 * Type B Past Week Summary
  * Fabian did inventory of parts/fasteners for dummy BS, RM, IM and IRM - almost all at Mitaka. A handful (picos, pico drivers) will be brought back from Kamioka.
  * Fabian continued work on Mathematica and Matlab models of the BS and control system. He now gets much better agreement after correcting discrepancies between the parameter sets.
  * Hirata-san worked on organizing:
   * Checking Mirapro assembly frame drawings
   * Ordering missing screws and small items (screws for dummy mass, fine pitch M8 for RM)
   * Work platforms and clean booth second floor arrangement.
   * Load gauge adapter and associated parts
   * Possible fall-back plans for the rods connecting the security structure to the PI.
   * Design for additional trim masses (existing design had no provision for adding/removing).		 === 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.
 * Eleonora and Izumi-san revisited the BS length to tilt coupling, which had degraded, and got it working again.

==== Plan for week of 4/23 ====
 * Shoda-san at Mitaka.
 * Hirata-san at Kamioka Mon-Wed, then Mitaka.
