Type-Bp (Shoda)

Past week report

• Top rid of PR2 and PR3 vacuum tank were fixed
  • Note that the feedthrough flanges are not closed yet.
  • During the fixing, we accidentally moved the injection beam of the Oplev. Alignment was lost.
  • We need to re-align the main beam. So far, we are planning to do it in the week of the commissioning WS.
• PR mirror position was measured by FARO.
  • The position of the mirror is off from the design by:
    • PR2: (-9.4, +0.5, -6.4)
    • PR3: (-3.5, -0.5, -4.9)
    • PRM: (+4.7, 4.6, -1.5) Note: PRM is fixed
      • Note that these values are relative to the side flange of the vacuum tank at the HR side. x is the norm of the flange surface, and z is the norm of optical bench.

Plan for coming weeks

• Release PRM. Setup the oplev
• WD test
