==== Report for week of 3/26 ==== ==== Report for week of 9/17 ====
 * Monday 9/17 was holiday.
 * We optimized the trim mass on the SF to get more balance torque with less total mass. We now have a reserve of 480 g for the yaw pico.
 * We set the SF damper gap to 6 mm.
 * We set the SR2 pitch with the optic lever, aligned the IRM and set all the OSEMs to have good clearance and midrange output.
 * We locked the SR2 suspension (except for the SF) and craned it into the tank.
 * We moved the vacuum feedthroughs over to the tank.
 * With help from Ohishi-san, we removed the First Contact from SR2.
 * Mark did an audit of all the electronics boxes and updated the item list and S-number file cards on JGWDoc.
 * Mark did an inventory of some thin arc weights and finalized the number to order (8*38 mm + 9*10 mm).
 * Panwei copied control filters over from the SR3.
 
==== Plan for week of 9/24 ====
 * Monday 9/24 is holiday (Autumn Equinox).
 * Mark, Hirata-san, Fabian, Panwei at Kamioka Tue-Fri.
===== SR2 =====
 * Remove First Contact.
 * Move SR2 in-air cables.
 * Unlock and realign suspension.
===== SRM =====
 * Set pitch of SRM and RM, tighten clamps, remove winch system.
 * Weigh IM/... section.
 * Build up SS to BF level.
 * Add BF.
 * Suspend IM and tweak height/balance.

 * Mark, Hirata-san, Fabian, Panwei at Kamioka Mon-Fri.
===== SRM =====
 * Cable/test BF.
 * Install IRM.
 * Install/cable/test IM OSEMs.
Line 10: Line 39:
 * BF No. 1:
  * Fujii-san finished tuning. Optimal load: 52.15[kg]. Resonance frequency: 0.36[Hz]. Optimal height: 64.7[mm].
  * We 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 replaced the blades corresponding to the BS and 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].
  * We measured the keystone tilt at different points, and the diferences are within 0.1[mm]

 * 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 diferences are within 0.3[mm]

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).


Others:

 * 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
 * --
 * 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!
 ==== Plan for week of 10/8 ====
 * Monday 10/8 is Sports Day.
 * Mark and Terrence (plus TBD) at Kamioka Mon-Fri.
 * Hirata-san, Fabian and Panwei at Kamioka Tue-Fri.
