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.
  • 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).
  • (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.
  • Split SRx real-time models?
