Report for week of 6/11

  • Enzo redid the SR3 BIO connections to match the now-working BS setup. He also fixed PR2, which had a similar problem.
  • Enzo replaced LPCDs with HPCDs in the SR3.
  • Hirata-san installed the cable clamps and Cu segments on the SF cap.
  • Hirata-san and Kozu-kun continued tuning the filter in PI #3. Unfortunately it seems to be rather weaker than expected, and we have not found a compression setting that gives a good frequency. We may have to use tricks like reducing the number of Cu segments on the SF (or using Al ones) to save weight.
  • Mark, Enzo and Terrence suspended the BF/... section from the SF, and got it aligned for TFs.

Plan for week of 6/18

  • Mark Enzo, Hirata-san, Kozu-kun, Terrence at Kamioka Mon-Fri.
  • --
  • Receive second and third sets of LBB damper rings.
  • Take TFs.
  • Cable, test SF LVDT and FR.
  • Add calculated ballast to SF.
  • Finish tuning F0 #3 for SR3.
  • Park F0 #1 (for SR2) in top of SR3 assembly frame.
  • Move F0 #3 behind SR3.
  • Move F0 #1 to "factory" area (in front of SRM) and start rebuild.
  • Install PI.
  • Suspend SF/... section.
  • Lots of cabling.

Plan for week of 6/25

  • Mark Enzo, Hirata-san, Kozu-kun, Terrence at Kamioka Mon-Fri.
