At Kamioka (Mark, Enzo, Simon, Type Bp team):
 * Mark remade the BF pico adapter cable which was poorly made and had also been damaged.
 * The Type Bp team tided up the BS rack and made new labels for many cables (thanks!).
 * Enzo connected up the in-air cables for the picos and steppers.
 * Mark and Enzo renumbered the PI LVDTs, geophones and LVDTs to make a consistent scheme working anticlockwise.
 * Enzo and Mark debugged all the cables. The only problem we couldn't solve was that the actuator coil for PI LVDT #0 is open-circuit at the connector on the LVDT. (It has been intermittent but worked before the craning.) We may have to redo the connector or replace the LVDT. Limited TFs will be possible in the next week.
 * Simon set up the LSOL and was easily able to get a return beam from the mirror on the dummy BS.
 * Shoda-san copied over the LSOL section of the PR3 real-time model into the BS model and made other improvements (thanks!).
 * Mark brought home

At Mitaka (Fabian, Hirata-san):
 * Fabian finished designing final trim masses for IM/BF/SF for the final hang of the BS and passed it to Hirata-san to make drawings and get quotes.
 * Hirata-san requested quotes for the replaceable-jaw version of the BS wire clamps.
 * Fabian and Hirata-san gathered needed items for the BS prism/flag gluing.
 * Hirata-san designed receptacles for the new rods with 8 mm heads and requested quotes.		  * Mark worked on SR2 planning.
 * Mark thought through what would be required to swap an optic (e.g., SRM) in situ (JGW-T1707436).
 * Hirata-san tried removing disks from IM flags (so we could reuse them in flag bases and make a complete set for SR2) but only got 1 of 4 out.
 * Hirata-san ordered more disks for IM flags.
 * Hirata-san asked for quotes on SF LBB blades.
 * Hirata-san got a reduced quote for the LBB damper rings.
 * Hirata-san received and cleaned suspension wires for the SR.
 * Fabian worked on the SR mass budget.
 * Fabian worked out the COM of the SR2 optic, and Mark used it to derive the proper prism positions.
 * Enzo and Kozu-kun worked on control filter design and installation.
Line 23: Line 19:
==== Plan for week of 7/3 ====
 * Do prism/flag gluing on real BS at Kashiwa (whole team).
 * Do new 3D CAD (Hirata-san):
  * SR2 on BS assembly frame. (Adjust jack positions if possible, or leave for Fabian/Mark to do.)
  * Final BS build, SS/PI/SF as for Test Hang but with BF/IRM/IM/BS/RM down rotated back to original direction.
   * On-assembly-frame version. (Adjust jack positions if possible, or leave for Mark to do.)
   * In-tank version.
 * Solve arc weight versus magic wand problem.
 * Do mass budget for LBB - design ballast masses (Fabian)
 * Run TFs, make improvements to real-time model (Mark, Enzo).		 ==== Plan for week of 11/27 ====
 * Fabian at commissioning workshop
 * Hirata-san at Kamioka Tue-Fri to work with Mirapro on SRM LBB installation.
 * All others (Mark, Enzo, Shoda-san, Kozu-kun) at Kamioka to start SR2 assembly.
  * Mark from Mon lunchtime.
  * Kozu-kun from Mon lunchtime through Wed.
  * Mirror gluing.
  * SR2 rack setup.
Line 34: Line 28:
==== Plan for week of 7/10 ====
Mark and Enzo at Kamioka:
 * Fix broken LVDT actuator coil.
 * Learn how Miyo-kun's pico driver software works and make improvements.
 * Test picos and steppers more fully.
 * Finish tidying rack and labeling cables.
Fabian and Hirata-san at Mitaka.
 * Design SR assembly frame.
 * Inventory for SR.		 ==== Plan for week of 12/4 ====
 * All at Kamioka
  * IM assembly and pico test.
  * Assembly frame alignment and optical table centering.
  * OL setup.

==== Vacation Info ====
 * Mark 12/22-1/3
 * Enzo TBD, probably 12/22-1/3
 * Fabian 12/22-1/5
 * Hirata-san 12/21-22 (conference)
