  * Fujii-san finished tuning.
  * Enzo wired the LVDT, Picomotor and Steppermotor.
  * 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.

  * Fujii-san disassemble the blades corresponding to the BS and we assemble the SR type blades.   * 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.
Line 25: Line 28:
  * 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.
  * 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]
Line 30: Line 33:
  * We measured the keystone tilt at x points: 65.5mm, 65.5mm, 65.5mm, and 65.5mm.   * We measured the keystone tilt at different points, and the diferences are within 0.3[mm]

Type B (Mark)

Report for week of 3/26

BFs:

  • 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 finished tuning 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
  • --
