==== Report for week of 3/26 ====

BFs:

 * BF No. 1:
  * Fujii-san finished tuning. Optimal load: 52.15[kg]. Resonance frequency: 0.37[Hz]. Optimal height: 64.7[mm].
  * We wired the LVDT, Picomotor and Steppermotor.
  * We measured the keystone tilt at different points and the differences are within 0.1[mm]
  * We added cable clamps to the base.

 * BF No.7:
  * Tanioka-san and Fujii-san replaced the blades corresponding to the BS for the SR type blades.
  * The yoke position was corrected.
  * The fishing rod was assembled.
  * Compression tuning is ongoing.??

SFs:

 * Hirata-san and Tanioka-san set up the frame to check the SFs.

 * SF (B2-5):
  * Hirata-san, Fujii-san and Tanioka-san checked the optimal load with and without cap. The optimal load changes about 250[g]. The cap didn't come out smoothly.
  * We measured the keystone tilt at different points, and the differences are within 0.1[mm] (65.5, 65.5, 65.5, 65.4)

 * SF (B2-6):
  * Hirata-san, Fujii-san and Tanioka-san checked the optimal load with and without cap (On going?).
  * We measured the keystone tilt at different points, and the differences are within 0.3[mm] (63.7, 63.5,63.8, 63.8)

SR3/SRM:

 * Kozu-kun and Enzo finished the SR3 in-air cabling.
 * Enzo prepared the SR3 and SRM rack in parallel (On going).


SR2:

 * Hirata-san tested the safety bars in the SR2 area.
 * We got new power supply for the SR2 Rack. Before, the power was coming from the BS rack.

BS:

 * Kozu-kun and Enzo helped Enomoto-san troubleshooting the BS Oplev issue (On going).

Shipping:

 * We received the LBB parts for SR2.
 * We received the Payload parts (IM and IRM) this morning.


==== Plan for week of 4/2 ====
 * Mark at Mitaka Mon, Kamioka from Tue.
 * Shoda-san at Mitaka
 * Others at Kamioka
 * --
 * Finish BFs tasks (cabling +calibration)
 * Finish SFs tasks (cabling +calibration)
 * Add cable clamps to bases.
 * Add cable clamps and Cu segments to caps (only if they fit well).
 * Build 2xIM, 2xIRM
 * Glue SR3 mirror?

 * Finish IMs and IRMs
 * Build 1xRM
 * 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.
