==== Past week report ==== Installation in Y-end:

21th(Tue)
  * Adjusted the height of release sensor for the dummy payload.
  * Adjusted the position of keystone stopper on BF.
  * Made the cables for LVDT and picomotor.
22th(Wed)
  * Completed cabling around the BF.
  * Closed the shell of BF.
  * Started preparation for the footholds.
23th(Thu)
  * Lifted down the EQ stop into the chamber and put the end plate for BF on the frame rock.
  * Set the footholds around the top chamber.
  * Extended the rods of EQ stop to the F3 stage.
  * Assembled the end plate for F3 and put it on the rods.
  * Prepared the F3 (cabling).
24th(Fri)
  * Put the F3 onto the end plate.
  * Connected the maraging wire for BF.
Line 13: Line 32:
 * Tune the F3.
 * Adjust the height of BF and F3.
 * Assemble the BF damper.
Line 20: Line 42:
 * Suspend BF and tuned the mass. Some of the masses are put inside the BF. The rest of the weight will be put on the cap after cabling.
 * Replaced the interface plate
 * Tried to replace the parts for Traversers. But they did not work well. Therefore, Uraguchi-san took them back to Mitaka again.
 * Cabling: some tools are bad for our cables and pins. Bad access around the SF.
