  • Install IM-IRM safety bar.
  • Swap SRM glass mass.
  • Seal geophones.
  • Find two geophone cables used by Okutomi-san.
  • Rewire one geophone cable correctly.
  • Add extra ≈1 kg to SF cap and adjust tilt.
  • Center and fasten F0 yoke.
  • Calibrate F0 GAS LVDT.
  • Add arc weights and geophones.
  • Test geophones.
  • Improve centering/tuning of IP and SS alignment.
  • Disconnect cables.
  • Remove crossbars.
  • Crane suspension into tank.

SR2 (not so low priority)

  • Run extension cord for OL.
  • Set up OL cabling.
  • Set up OL.
  • Add more arc weights and tweak IP centering.
  • Replace two borrowed geophones.
  • Remove tape, writing etc on PI and PI items.
  • Add new feedthrough to lower part of tank (with Izumi-san-tachi).
  • Install cable for MIF pico on LBB (with Izumi-san-tachi).

SR Prep Tasks - To Be Scheduled

Tunnel

  • Check which LVDT cards are in which boxes.
  • Get at least one BIO Converter chassis fully connected (CONTEC BIO card, WD and stepper motor chassis) for implementation and test of stepper motor reset function.
  • Install, cable PI yaw steppers.
  • Correct flipped connections in SRM PI LVDTs.
  • Check SR2, SR3 TM coil gains for magnet polarity compensation.
  • Replace chipped magnets (12x12x12 mm) in SR3 IP, H1 and H2.

Mitaka or remotely

  • Write generic Type B Guardian; make BS and SR3 inherit from it; make analog WD optional for now (all suspensions will get them eventually).
  • Create software stepper drivers for SR3 and SRM and link to them from STEP_MASTER.adl screen.
  • Make three in-air stepper splitter cables for SR2, SR3 and SRM. [done?]
  • (Continue to) soak the sapphire prisms off the dummy BS for reuse on the SRM metal mass.
  • Install damping filters for SR2.
  • Review DAC channel requests.
  • Set up SR2 Guardian.
