Type B Past Week Summary
- Mark and Hirata-san at Mitaka
  - Gathered parts for cable making.
- Mark and Hirata-san at Kamioka:
  - Replaced the floor panels that had been taken from the PR2 area (filling in the hole in the floor) and found/installed two new panels to act as bridges near the BS assembly frame.
  - Installed two more LPCDs and the stepper motor driver in the PR2 rack.
  - Ran cables from the rack to the second and third sat amps (for the IRM OSEMs).
  - Added a second DIO card in the rack and connected it to the BIO inputs and outputs of the new LPCDs.
  - Started making extension cables for RM-H2 and -H3 OSEMs but gave up due to complicated grounding arrangement.
  - Washed four 40-cm D-Sub-9 ribbon cables to use as temporary extensions (maybe also for H1/H4).
  - Added extension to the IM pico cable for the BF yaw pico.
  - Made LVDT adapter cable.
- Mark worked on schedule.

 Line 6:
-  * Fabian, Mark and Liu-kun did BS installation at Kamioka:
   * Debugged the issue with the BF keystone being tilted enough to cause rubbing on the yoke for the magnets. It was solved by moving the yoke ≈1 mm taking advantage of the oversized holes.
   * Measured the height of the payload as a function of trim mass. The BF spring seems to have a slightly lower load capacity and a rather higher spring constant than when it was remeasured by Hirata-san.
   * Removed IM trim mass to set the average height of the keystone to the CAD value.
   * Moved IM trim mass around to set the pitch of the dummy BS.
  * Hirata-san
   * TBD.
