Past week report

[SRM]

  • Dismounted the top filter for SRM from the IP for Type-A. Packed the IP to the box.
  • Combined the top filter and the IP.

[Y-front]

  • Transported the IPs from/to the first floor.
  • Measured the transfer functions of the BF/F3/F2 by the digital system.
  • Cabled in the F1.
  • Assembled the cup of F1 (Cu plates, connector plates) and closed the cup.
  • Measured the weight of F1.

[X-front]

  • Evaluated the ACCs.
  • Fixed the cables between the cryo-payload (CP) and the BF at the lower points on the wire.
  • Connected the cables to the BF.
  • The CP was installed and suspended from the BF.
  • Adjusted the height of CP. The height of BF was set to 67.5mm.

Plan for coming weeks

  • Setting of the F1 in Y-front.
  • Setting of the top filter in X-front.

Type B (Mark)

Report for week of 7/17

  • We checked the polarity of the IP LVDTs and flipped coil connections to get the standard arrangement.
  • We debugged an issue where one of the LVDT actuators had half the magnets in backwards resulting in no force.
  • We calibrated all the PI LVDTs.
  • We set the SF damper ring gap.
  • We prepped the suspension for craning, moved it into the tank and hooked the LBB damper ring rods.
  • Type A merged the SRM F0 with the correct IP, and we moved it out of the way (to the second floor behind the SRM tank).
  • We installed more cable clamps on the SR2 PI.

Plan for week of 7/23

  • Mark, Enzo, Fabian, Kozu-kun, Terrence, Panwei at Kamioka Mon-Fri.
  • Hirata-san at Kamioka Mon-Thu.
  • Mirapro moves assembly frame ≈7/25 (Wed).

SR3
  • Unlock suspension.
  • Rearrange cables.
  • Test.

SR2
  • Finish PI prep.
  • Crane into AF, suspend.
  • Start cable routing.

SRM
  • Prepare to assemble SRM metal mass (most parts due Wed 7/25).
  • Help Mirapro with AF move.
  • Start rebuild of top filter of PI #2.
