Today's activities

Workers: Akutsu, Michimura, K. Tanaka (17:30-21:30)

GPT part installation

  • Installed optics for green path from GBS1, except for green QPD boards (See JGW-T1808962 for optical layout)

    • we marked screw holes on optical table every 10 holes
    • we labeled all the mirror mounts with the part number of the optic
    • the position of GST2 was 25mm too far from GLNS1, so we moved it to the default position
    • beam seems to be focused at around GST3, as expected
  • Other things
    • Height of Gig-E camera is a bit short
    • All the LVDT outputs went close to zero from around 21:26. We didn't notice this until we got back to the control room.

Next Plan

  • Align and balance the BRT and the TMS-VIS.
  • Detach the remaining white tapes just before closing the chamber; be noted that there are white tapes on the PEEK connectors at the inside of the flanges.
  • Torque completely the bolts which are fixing the upper and the lower base plates.
  • Insert metal gaskets before torquing the ICF203 flanges with Dsub connectors.
  • Modify MEDM screen
    • Add DC PD and so on.

  • Cable Dsub 15pin for TMS-VIS OpLev.

  • Modify cabling for DC PD.
  • Return plastic box.
  • Install rails in digital rack.
    • They may be necessary under LVDT distributor, geophone distributor, and WHT board.
    • Nagano is not sure it is necessary under HP coil driver.
  • Consider how to cable Dsub cables to QPD.
  • Investigate LVDT outputs
  • Install QPD boards and do the final cabling
  • Check why Gig-E camera is not working
  • Install IR optics

Wanted!

  • M4-12mm (or longer) screws instead of M4-10mm for fixing mirror holders to 20mm dia. posts
  • Spacer for Gig-E camera (height is shorter than 4-inch right now)
