SR Prep Tasks - To Be Scheduled

Tunnel

  • Retrieve BNC-Lemo cable from Nakano-kun.
  • 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 SR3 PI yaw stepper.
  • Correct flipped connections in SR2 PI LVDTs.
  • Correct flipped connections in SRM PI LVDTs.
  • Grab and configure a picomotor driver as SR2_BF 10.68.150.25.
  • Get independent power supply for SR3 so SR2 can be powered back up.
  • Check SR2, SR3 TM coil gains for magnet polarity compensation.
  • Calibrate last six IM OSEMs.
  • Rebuild filter in PI #1.
  • Install clamps on PI #1.
  • Install geophone plates on PI #3.
  • Install geophone plates on PI #1.
  • Install correct IP in PI #2.
  • Rebuild filter in PI #2.
  • Install clamps on PI #2.
  • Install LBB blade units on PI #2.
  • Install geophone plates on PI #2.
  • 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.
  • Set up SR2 Guardian.
  • Install damping filters for SR2.
  • Review DAC channel requests.
  • Set up SR2 Guardian.
  • Install damping filters for SR2.
  • Split SRx real-time models?
