  • F0 Stepper.
  • SF Stepper.
  • BF Stepper.
  • IP Steppers.
  • IP LVDTs.
  • Geophones.
• Check SF keystone height and offload with FR as necessary.
• Adjust ballast/trim mass of SF, with reserve for yaw stepper.
• Set SF damper magnet ring height.
• Check/tweak optic pitch.
• TFs.

SRM

• Add TM OSEM cables.
• Set TM pitch and tighten clamps.
• Set RM pitch and tighten clamps.
• Remove winch system and restore items removed from top of IM.
• Suspend and weigh IM/... section.
• Add BF crossbars to SS.
• Build up SS to BF level.
• Suspend IM/... section and adjust ballast/trim masses.
• Install feedthroughs on AF (3 available; need to get a 4th).
• Arrange power to SRM rack and get it running.

• Check the IRIG-B 9999xx fix has been applied (klog http://klog.icrr.u-tokyo.ac.jp/osl/index.php?r=6031).

SR3

• Don't even think about doing anything with SR3.

SR Prep Tasks - To Be Scheduled

Tunnel

• Add SR3 LBB ballast mass.
• Install SR3 LEN OL.
• Rebuild PI #2 F0 for SRM.
• 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 SRM PI LVDTs.
• Grab and configure a picomotor driver as SR2_BF 10.68.150.25.
• Check SR2, SR3 TM coil gains for magnet polarity compensation.
• Rebuild filter in PI #2 for SRM.
• Clean/Replace yoke in PI #2 for SRM.
• Install clamps on PI #2 for SRM.
• Install LBB blade units on PI #2 for SRM.
• Install geophone plates on PI #2 for SRM.
• 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?
