Main Assembly Sequence

  • Account for second bubble level (might be on BF).
  • Borrow portable hard drive.
  • Clean up sticker residue and magic marker writing.
  • Remove LVDT modules; identify and replace screws.
  • Check that all in-air cables are labeled.
  • If possible, reroute cable to eliminate need for fifth feedthrough.
  • Debug all electronics, especially actuation.
  • Measure IP period; adjust ballast mass.
  • Calibrate all LVDTs. BF, SF, PI-GAS, PI-H1, PI-H2, PI-H3

  • Calibrate IP LVDT sensing against IP LVDT actuation, IP FRs.
  • Set all EQ stops to TBD clearance.
  • Install small KOACH filters on LBB.
  • Remove First Contact.
  • Cable optical lever (Simon, Enzo)
  • Align optical lever (Simon)
  • Get ready for full TFs.

Etc

  • Move stuff out of PR2 area.
  • Tidy/label parts.
  • Move safety bars from BS AF area to SR2 area.
  • (Put up safety bars in SR3 area.)
  • Close hole in floor above BS AF area.

Software

  • Enter new IP matrices and do safe.snap.
  • Send stepper driver info to Miyo-kun.
  • Update real-time model to number channels from #0.
  • Remove old OL stuff; add link to new OL stuff.
  • Remove unused screens.
  • Sort out SVN.
  • Add support for comments to SUMCON.
  • Create SUMCON model with values commented.
  • Derive matrices for IP FRs.

Tasks Not To Forget

Major Tasks

  • Update BS Install Procedure with screenshots from new on-assembly-frame 3D CAD.
  • Finish assembly drawing for LBB and LBB damper ring and post on JGWDoc (Hirata-san).
  • Figure out how to make PI yaw adjustment reliable.

Minor Tasks

Mechanical

  • Put pointy-tipped screw in RM trolley for BS
  • Return/replace borrowed parts:
    • Temporary ballast mass (dog clamps) in BF.

Electrical

Real-time and SUMCON models

  • Create SUMCON models for full BS and major installation milestones.
  • Create controls design description (cf LIGO-T1100378).

  • Make table of ADC/DAC assignments and check for consistency with D1503600 and k1visbs (Enzo, Mark)
  • Understand/document/debug Kokeyama-san's DIO stuff.
  • Measure LPCD and HPCD output filter response.
  • Design and install software compensation filters for LPCD and HPCD output filters.
  • Design and install GAS drift compensation filters.
