Type-Bp (Shoda)

Past week report

  • PRM installed
    • The suspension was installed.
    • But we found that the tank cannot be placed at the +y side of the PRM, since the space inside the clean booth was so tight. The tank was moved to the -y side using the fork lift and crane thanks to Kimura-san, Sawada-san, and Endo-san.
    • Cabling was almost done, but not yet checked.
    • Pylons for oplevs are installed. But no view port, nor oplev setup.

Plan for coming weeks

  • No site work in the week of Sep. 25th
  • In the week of Nov. 2nd:
    • Cabling check
    • Remove all the FC for the interferometer alignment, which will start from Nov. 10th.
    • Oplev setup, including viewport.
    • Suspension release and status check.
    • PR2 BF GAS status check. Turning on PR2 damping.
