Line 5: Line 5:
 * Hirata-san:
  * Updated the 3D assembly model for BS (among other issues, it turned out that parts were not correctly mated near where the suspension sits on the hydraulic jacks in the tank).
  * Liaised with IJECT.
  * Made an inventory for Type B (BS and SR).
  * Packed and shipped second winch to Kamioka.
  * Packed some jigs for adjusting BF blades.
  * Attended NINS information security seminar.
  * Attended the public hearing for the Opt-IR Research Division Chief Election.
 * Mark, Fabian, Enzo
  * Cabled IM picos and used IM yaw pico for adjusting RM. (Later, a wire broke at the connector, disabling the IM yaw, but we were able to continue by manually rotting the pic.)
  * Helped Takahashi-san in adjusting BF.
  * Initial round of adjustment made transverse perfect but overshot in longitudinal and made vertical unstable.
  * Second round of adjustment made vertical stable but left longitudinal offset.
  * Concluded that we can probably manage without bringing the BF back to Mitaka, but it will take some careful surveying of the existing offset and several more days of adjustment.		 === Type B (Mark) ===
==== Past week report ====
At Kamioka (Mark, Fabian, Hirata-san, Yoshioka-kun):
 * We reconfigured the top of the assembly frame.
 * We cleaned the assembly frame, blowing dust out of the grooves and wiping all surfaces.
 * We recentered the optic table in the bottom of the frame and adjusted the frame until the top was centered over the optic table. We also recentered the trolleys.
 * We re-installed, centered and leveled the IM.
 * We solved two issues with the new wire clamps:
  * Some holes were not properly threaded - Hirata-san retapped them.
  * Some locating pins were loose - we glued them.
 * We mounted the BS mirror box on the trolley and brought it under the IM.
 * We installed the winch system and the 300 µm wires for the BS.
 * We set up the optical lever.
 * Hirata-san finished the new BF. We moved the old BF out of the cleanbooth and the new one in.
 * We suspended the BS and set its height and pitch.
