 * 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 so as to remain consistent with PRx).
   * 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)
