 * 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) ===
==== Report for week of 3/26 ====

BFs:

 * BF No. 1:
  * Fujii-san finished tuning.
  * Enzo wired the LVDT, Picomotor and StepperMotor.
  * We measured the keystone tilt at 4 different points and it was at 65.5, 65.5, 65.5 and 65.5.
    So with the differences of 0.1 mm we think we can tolarate this differences.
  * We added cable clamps to the base.

 * BF No.7:
  * Fujii-san disassemble the blades corresponding to the BS and we assemble the SR type blades.

SFs:

 * Hirata-san and Tanioka-san set up the frame to check the SFs.

 * SF (B2-5):
  * Hirata-san, Fujii-san and Tanioka-san checked the optimal load with and without cap. The optimal load changes about 200[g].
  * We measured the keystone tilt at x points: 65.5mm, 65.5mm, 65.5mm, and 65.5mm.

 * SF (B2-6):
  * Hirata-san, Fujii-san and Tanioka-san checked the optimal load with and without cap (On going?).
  * We measured the keystone tilt at x points: 65.5mm, 65.5mm, 65.5mm, and 65.5mm.

 * Kozu-kun and Enzo finished the SR3 in-air cabling.

 * Enzo prepared the SR3 and SRM rack in parallel (On going).

 * Kozu-kun and Enzo helped Enomoto-san troubleshooting the BS Oplev issue (On going).



 * We finished tuning of BF No. 1.
  * We wired the LVDT, Picomotor and StepperMotor of BF No. 1.
Line 28: Line 43:

 * We finished tuning of BF No. 7.
  * We wired the LVDT, Picomotor and StepperMotor of BF No. 7.



 * SF check (Hirata-san++).
  * We checked the load capacity with and without the cap.
  * We checked fit of caps. For the SF No.
  * Add cable clamps to bases.
  * Add cable clamps and Cu segments to caps (only if they fit well).
  * Cable LVDTs and steppers.

 * We finished the SR3 in-air cabling.

==== Plan for week of 4/2 ====
 * Mark at Mitaka Mon, Kamioka from Tue.
 * Shoda-san at Mitaka
 * Others at Kamioka
 * --
 * Glue SR3 (if available)
 * Build 2xIM, 2xIRM (if parts available - due 3/30)
