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

  • 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)
