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 different points and the diferences are within 0.1[mm]
    • 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).
  • We finished the SR3 in-air cabling.
