[X-end]
  * Recovered the black out.
  * Checked signals for the BF damper.
  * Set the remote operation of the stepping motors.
  * Closed the top chamber.
  * Closed the cross tube.
  * Set the remote monitor of the vacuum gauge.

[Mitaka]
  * Assembled the BFs. One BF was completed. The other was assembled by a half.
  * Checked the ACCs. Two of six units have a problem.
Line 20: Line 34:
  * Start evacuation in X-end.
  * Finish the assembly of BFs.
  * Service the ACCs.

[Plan in November]
  * 11/6-10 X-end: Disassembly of the EQ stop and the cabling.

==== Plan for coming weeks ==== At Kamioka (Mark, Fabian, Enzo, Hirata-san):
 * Hirata-san did an inventory of SR and other parts at Kamioka.
 * 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).
