Preparation for SR Installation

Every Week

Facilities

  • Vacuum and roll floor.
  • Wipe ladders, assembly frame.
  • Tidy tools, parts.
  • Get stuff from ../WishList

Coming Weeks

2018-12-17

SRM

  • Install/test new yaw mechanism.
  • Adjust height.
  • Check/adjust optic pitch; release LED to SR2.
  • Install Enomoto-kun's beam target plate (if available).
  • Install extension cord for pico drivers.
  • Find two geophone cables used by Okutomi-san. (I looked in the second floor EXV room but didn't find them - Mark.)
  • Find one geophone cable ordered for SRM but missing.
  • Rearrange miswired geophone cable.
  • Rebuild defective geophone cable.
  • Seal geophones.
  • Install geophones and arc weights.
  • Center IP.

SR3

  • Install/test new yaw mechanism.
  • Adjust height.
  • Realign OL.

SR2

  • Install/test new yaw adjuster.
  • Adjust height.
  • Get top plate reduced?
  • Set up OL cabling.
  • Set up OL.
  • Remove tape, writing etc on PI and PI items.
  • Add new feedthrough to lower part of tank (with Izumi-san-tachi)?
  • Install cable for MIF pico on LBB (with Izumi-san-tachi)?
  • Add ballast mass to LBB.

SR Prep Tasks - To Be Scheduled

Tunnel

  • 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?

Ordering
