==== Report for week of 4/2 ====

 * Fujii-kun and Yamamoto-kun got the SR3 real time model running.
 * We received the SR3.
 * However Mark and Tanioka-kun found Hirose-san had applied the First Contact patterns on the wrong sides, so we took it to Yamamoto-san's lab and Toyama University and re-applied the FC properly. We also bounced a 1064 nm beam off it to verify that the HR and AR coatings were not also swapped (they were OK).
 * We made magnet-standoff assemblies for both SR3 and SRM, and set up for gluing the prisms and magnets. We will attach the prisms and magnet-standoffs on Monday.
 * Hirata-san did inventory of the SR3/SRM payload parts received last week and started on the inventory of screws.
 * Fujii-kun, Enzo and team finished the preparation, adjustment of the SFs and BFs.
 * They calibrated one SF and BF. (The remaining one SF and BF will take about another day. Also, the FR stops need to be checked.)
 * Enzo and Kozu-kun finished setting up the SR3 and SRM racks. (The SRM rack still lacks a front-end, and power and network connections, but the SR3 is now ready for testing.)
 * Shoda-san worked on getting quotes for the ballast masses, on design of the SRM metal mass, and on splitting the BS model to reduce the load on the front-end computer.

==== Plan for week of 4/9 ====
 * Shoda-san at Mitaka
 * Fujii-san at Mitaka
 * Tanioka-san at Kamioka, but possibly doing PEM stuff.
 * Others at Kamioka
 * --
 * Finish SRM BF and SF calibration
 * Finish IMs and IRMs
 * Glue SR3 mirror
==== Report for week of 4/9 ====
 * Mark glued prisms and magnet/standoff assemblies on the SR3. The SR3 needed to be raised in the box by 0.7 mm to make the prisms go on at the right height, which was done using M4 washers under the PEEK feet.
 * Mark glued ferromagnetic disks on the last 5 IM flags. This completes 2 sets, for SR3 and SRM.
 * Mark configured two pico motor drivers ordered by Takahashi-san as SR3-IM and SRM-BF.
 * Enzo and Kozu-kun finished preparing and calibrating the SF and BF for SR3 and almost entirely finished with those for SRM.
 * Hirata-san built two IMs for SR3 and SRM, and tested the pitch and roll adjustment by running each mass to both limits of its range with the pico driver.
 * Shoda-san worked on the design of the metal SRM.
