 * Type B Past Week Summary
  * 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.

==== Report for week of 12/25 ====
 * Hirata-san got the L-brackets machined and washed, and installed them on the IM ring bars.
 * Shoda-san recovered the BS from the power outage on 12/25.
 * Miyakawa-san fixed an issue with the SR2 RTM which had prevented it from running.
 * Shoda-san, Hirata-san and Kozu-kun weighed the IM without ballast masses, and then added the lower masses and installed the IM on the assembly frame.
 * They cleaned the assembly frame and installed new jack receptacles on the load gauge adapter.
 * They installed the winch system on the IM, and inspected the clamp pieces for possible scratches.
 * They ran cables for the SR2 steppers and OSEMs.
