Real BS Hang Tasks

Major Tasks

  • Finish assembly drawing for LBB and LBB damper ring and post on JGWDoc (Hirata-san).
  • LBB ballast mass.
    • Research real payload.
    • Do improved mass budget.
  • Get pico drive screens fixed (Miyo-kun)
  • Final ballast mass production for BF and SF (Hirata-san). (have quotes)
  • Design of receptacles for rods with 8 mm heads.
  • Possible rebuild of BF and/or SF
    • Set up build/test stand for filters.
    • Get filter test weights.
    • Find spare BF blade(s).
  • Reclean stuff:
    • PI (remove Kapton tape etc, etc).
    • LLB damper stuff, especially Cu segments.
  • Calibrate PI vertical LVDT.
  • Set yoke on PI vertical LVDT (if necessary).
  • Calibrate PI horizontal LVDTs.

Minor Tasks

Mechanical

  • Get clean bag laundered.
  • Put pointy-tipped screw in RM trolley for BS
  • Swap out temporary ballast mass in BF, SF.
  • Return/replace borrowed parts:
    • Lock washers for LBB dampers
    • Temporary ballast mass (dog clamps) in BF.
    • Wide-mouth OSEMs from RM to Akutsu-san
  • Adjust height of crossbars below BF.
  • If possible, fix galled pole in BF level of EQ stop.
  • Swap in new F0-SF maraging rod (with 8-mm heads) and new receptacles to match.
  • Check inside SF for lost ruler.
  • Tighten PI yaw return spring.
  • Get Cu O-rings for feedthroughs.

Electrical

  • Decide final in-vacuum and in-air cable routing (Enzo).
  • Calibrate all LVDTs (Enzo, Mark).
  • Remove cling wrap in BF and install vacuum-compatible heat shrink.
  • Remove cling wrap on connections for PI vertical stepper and install vacuum-compatible heat shrink (needs wider diameter heat shrink or smaller pins).
  • Rewire PI horizontal steppers with vacuum-compatible cable.
  • Adjust yoke on BF to put top of secondary at 6 mm above top of baseplate (or to give ≈0 counts at nominal height).

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.
  • Create a proper DAC Monitor MEDM screen.
  • Improve ADC Monitor MEDM screen.

SR Prep Tasks

Design/Purchasing

  • Do rough mass budget for SR2/SR3/SRM.
  • Design SR assembly frame.
  • Design final SF ballast masses (Fabian).

Electronics

  • Get cables/cards for SR3:
    • 5 DSub-37 cables (tent)
    • 5 DSub-15M to DSub-9M adapter cables (tent)
    • 3 DIO cards (tent)
    • 2 DSub-9 FF gender benders (for LVDTs)
