Past week report

At Kamioka (Mark, Fabian, Enzo, Hirata-san):

Hirata-san published his inventory of SR parts on Dropbox.
Mark and Enzo finalized the geometry matrices for the IP, entered them in MEDM and updated the safe.snap.
Mark, Enzo and Fabian worked with Izumi-san et al. to align the BS. We got the +Y beam fairly close to aligned (to the second gate valve, near IY).

Plan for week of 11/13

Kamioka: Mark

Attend commissioning workshop at U Toyama.
Be person-on-site for BF work.
Set up for mirror gluing.

Mitaka: Fabian and Hirata-san

SR procurement.
New PI GAS FR design.
BS LBB ballast mass design.

- * 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.
