 * BF No. 1:
  * Fujii-san finished tuning.
  * Enzo wired the LVDT, Picomotor and StepperMotor.
  * We measured the keystone tilt at 4 different points and it was at 65.5, 65.5, 65.5 and 65.5.
    So with the differences of 0.1 mm we think we can tolarate this differences.
  * We added cable clamps to the base.

 * BF No.7:
  * Fujii-san disassemble the blades corresponding to the BS and we assemble the SR type blades.

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 200[g].
  * We measured the keystone tilt at x points: 65.5mm, 65.5mm, 65.5mm, and 65.5mm.

 * 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 x points: 65.5mm, 65.5mm, 65.5mm, and 65.5mm.

SR3/SRM:

 * Kozu-kun and Enzo finished the SR3 in-air cabling.

 * Enzo prepared the SR3 and SRM rack in parallel (On going).

BS:

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




 * We finished tuning of BF No. 1.
  * We wired the LVDT, Picomotor and StepperMotor of BF No. 1.
  

 * We finished tuning of BF No. 7.
  * We wired the LVDT, Picomotor and StepperMotor of BF No. 7.



 * SF check (Hirata-san++).
  * We checked the load capacity with and without the cap.
  * We checked fit of caps. For the SF No.
  * Add cable clamps to bases.
  * Add cable clamps and Cu segments to caps (only if they fit well).
  * Cable LVDTs and steppers.

 * We finished the SR3 in-air cabling.

==== Plan for week of 4/2 ====
 * Mark at Mitaka Mon, Kamioka from Tue.
 * Shoda-san at Mitaka
 * Others at Kamioka		 ==== Plan for week of 6/18 ====
 * Mark Enzo, Hirata-san, Kozu-kun, Terrence at Kamioka Mon-Fri.
Line 68: Line 29:
 * Glue SR3 (if available)
 * Build 2xIM, 2xIRM (if parts available - due 3/30)

==== Plan for week of 4/9 ====
 * Shoda-san at Mitaka
 * Others at Kamioka
 * --
 * Finish IMs and IRMs
 * Build 1xRM

==== Plan for week of 4/16 ====
 * Start SR3 Hang?

==== Plan for week of 4/23 ====
 * F0 blade prototype test

==== Plan for week of 4/30 ====
  * Golden Week!		  * Install PI.
 * Suspend SF/... section.
 * Lots of cabling.
