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.
  • Install damping filters for SR2.
  • Split SRx real-time models?
