Line 7: Line 7:
 * Hirata-san:
  * Worked on the PR optic removal jig.
 * Enzo-san
  * Worked on getting his drivers license.
 * Mark, Fabian (at Kamioka):
  * Tried different strategies for getting the IRM-IM EQ stops and IRM OSEMs to line up simultaneously.
  * Realized that the main problem was that the pitch of the BS had changed relative to the IM (presumably due to slight slippage of the wires) so the IM had to be pitched up by 16 mrad to get the BS pitched slightly down (4.7 mrad).
  * Took the sides off the IRM to get access to the clamps and tightened them to prevent further slips.
  * Rebalanced the IM to be level in pitch (and roll).
  * Reassembled the IRM and aligned the IRM-IM EQ stops - this time it was easy.
  * Adjusted the IRM and RM OSEMs to mid-range.
  
==== Plan for coming weeks ====
 * Mark and Enzo come to Kamioka and work on rack and cabling.
 * Fabian works on design, including SR assembly frame.
 * 		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.

Site closure: Friday<<BR>>
Vacation: Enzo (Mon), Fabian (Mon-Fri)<<BR>>
Kamioka: Mark (Mon-Thu), Enzo (Tue-Thu), Yoshioka-kun (Tue, Wed), Ohishi (TBD).<<BR>>
 * Adjust RM OSEMs; add new RM cable clamp piece.
 * Hang RM.
 * Run new (longer) OSEM cables.
 * Weigh/trim BS/RM/IM.
 * Suspend BS/RM/IM, add IRM.
 * Lay new in-air OSEM cables.
