 * 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.
  		  * Activity report for weeks of 12/26 and 1/2

  * Hirata-san:
   * Modified parts list and screw list for payload.
   * Sent lists to i-ject and asked for preliminary quotes.
   * Made drawings for some jigs (PR hold-down jig) and some parts for payload (PR/SR wire clamps with disposable jaw pieces - improved version with disposable pieces in both primary and secondary clamps).
   * For Type Bp:
    * Searched for PR gluing jigs.
    * Washed and assembled recoilmass base for mirror hanging jigs, and sent them to Kamioka.
    * Washed additional masses for IM and sent them to Kamioka.
   * For others:
    * Washed IMMT plate and sent them to Kamioka.
  * Fabian
   * Designed a pull down system to fix the PR IM to the EQ stop (similar to the SR one).
   * Worked on design of the SR assembly frame. As hoped, the SR version can be almost identical to the BS version.
   * Worked on design of additional trim mass (≈18 kg) for the BS BF.
   * Checked assembly PR/SR drawings. There were a few corrections/changes.
   * Checked fastener list. There were few corrections/changes.
   * Checked component list for the manufacture order. There were few corrections/changes.
   * Helped in searching for the PR gluing jigs.
  * Mark
   * Started design of SR assembly frame (but then passed it to Fabian).
   * Worked on task lists and schedule.
 * Plan for 1/10-13
  * Mark and Fabian at Kamioka:
   * Finish rebalance of IM
   * Reinstall IRM, adjust OSEMs
   * Replace broken Type 3 cable.
   * Do TFs from IRM OSEMs to IRM and IM OSEMs.
   * Cable up and test BF LVDT and fishing rod (time permitting).
   * Disconnect BF and ship back to Mitaka (time permitting).
  * Hirata-san:
   * More SR procurement.
