 * Type B Past Week Summary
  * Mark (with Enzo) did initial TFs on the BF.
   * Did fixed-sine TFs on individual OSEMs at low frequency to check actuator polarity (klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=2176 | 2176]] and [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=2182|2182]]).
   * Set gains in the COILOUTF block to compensate for actuator polarity.
  * Mark (with Enzo) did a free-swing measurement on the BS after earthquake of 11/22 (klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=2182|2182]]).
   * Results suspicious (noted by Shoda-san): too much difference between OSEMs - horizontal showing much less motion than vertical.
   * Possible rubbing in horizontal.
   * May need a trip to Kamioka.
  * Mark (with Enzo) made corrections and improvements to many of the MEDM screens (klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=2176 | 2176]] and [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=2182|2182]]).
   * Main overview screen was not generic in many places, and links to GDS_TP screens were broken.
   * ADC monitor screen referenced bad channels with LIGO-style names.
   * DAC monitor screen was not generic and did not support IM OSEMs.
   * Watchdog IM OSEM AC band limit filter screen was a copy of the TM one.
   * Watchdog TM OSEM AC band limit filter screen appears to be getting OL signals as input - needs model changes to fix.
   * The zoomed screens for IM OSEM centering were called incorrectly and did not work.
   * Various screens had LIGO-style channel names as labels.
  * Mark did a draft of D1603600-v12, including:
   * New assignment of IM OSEMs to DAQ channels (#4-9 are now V1, V2, V3, H1, H2, H3 rather than H1, H2, ...) from last Friday (the wiring was changed to reflect the model).
   * Information on how to identify the wires from the steppers and LVDTs so that the adapter cables can be plugged in properly.
  * Mark worked on schedule.
  * Hirata-san did drawings for new 8-mm maraging wires for Type A.
  * Hirata-san worked on PR/SR mirror box modifications with Shoda-san.
=== Type B (Mark) ===
==== Past week report ====

 * We brought the SR2 optic into the tunnel and moved it into the good mirror box. The spare mirror was moved into the not-so-good mirror box.
 * Enzo assembled the SR2 rack and laid all the long cables from the rack into the cleanbooth. (Hayakawa-san can now proceed with the rebuilding of the changing cleanbooth.)
 * Mark and Shoda-san took data for calibrating and diagonalizing the OL. (Due to the odd angle of the first steering mirror, the beam pattern is rotated by 62° at the QPD.)
 * Enzo found nearly all in-vacuum cables.
 * Enzo and Shoda-san got several more loops closed on the BS.
 * Mark found three geophone pods and two feedthrough adapters for SR2 (now have 3 FAs but need 4).
 * Mark took out S-numbers for anonymous boxes in the SR2 and put yellow stickers supplied by Tomura-san on them.
 * Hirata-san worked on SR procurement.
 * Hirata-san worked with Mirapro to get the SRM LBB installed in the tank.
 
==== Plan for week of 12/4 ====
 * Mark at Kamioka.
 * Fabian at f2f satellite meeting Mon, then Kamioka.
 * Enzo at f2f then Mitaka.
 * Hirata-san at Kamioka Mon-Thu, Mitaka Fri.
 * Kozu-kun Thu only.
 * Mirror gluing.
 * IM assembly and pico test.

==== Plan for week of 12/11
 * Mark, Fabian, Enzo, Hirata-san, Shoda-san at Kamioka.
 * Kozu-kun Mon-Thu only.
 * Assembly frame alignment and optical table centering.
 * Move trolley system from SR3.
 * OL setup.

==== Plan for week of 12/18 ====
 * Shoda-san vacation
 * Mark, Fabian, Enzo, Kozu-kun at Kamioka Mon-Wed.

==== 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)
