Line 5: Line 5:
 * Hirata-san:
  * Updated the 3D assembly model for BS (among other issues, it turned out that parts were not correctly mated near where the suspension sits on the hydraulic jacks in the tank).
  * Liaised with IJECT.
  * Made an inventory for Type B (BS and SR).
  * Packed and shipped second winch to Kamioka.
  * Packed some jigs for adjusting BF blades.
  * Attended NINS information security seminar.
  * Attended the public hearing for the Opt-IR Research Division Chief Election.
 * Mark, Fabian, Enzo
  * Cabled IM picos and used IM yaw pico for adjusting RM. (Later, a wire broke at the connector, disabling the IM yaw, but we were able to continue by manually rotting the pic.)
  * Helped Takahashi-san in adjusting BF.
  * Initial round of adjustment made transverse perfect but overshot in longitudinal and made vertical unstable.
  * Second round of adjustment made vertical stable but left longitudinal offset.
  * Concluded that we can probably manage without bringing the BF back to Mitaka, but it will take some careful surveying of the existing offset and several more days of adjustment.

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

BFs:

 * 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.

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

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

 * 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.
