SR Prep Tasks - To Be Scheduled

Tunnel

• Retrieve BNC-Lemo cable from Nakano-kun.

• 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.

• 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.
