 * 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.
