 * Suspensions
  *
 * Suspensions(R.Takahashi)
  * Mechanical Motion
   * Smooth pico motion and its default position
    * MCi/o: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28907 -> --(A.I. upload picth pico pictues (R.Takahashi), or taking picture for picth pico.)-- -> https://klog.icrr.u-tokyo.ac.jp/osl/?r=28941
    * MCe: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28909 -> --(A.I. upload picth, yaw pico pictues (R.Takahashi), or taking picture for picth, yaw pico.)-- -> https://klog.icrr.u-tokyo.ac.jp/osl/?r=28941
   * Gaps between magnets and coils -> MCo uppper is the minimum, but this is the best effort.
   * Gaps between EQ stoppers and mirrors -> confirmed less than 1mm.
    * MCe: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28915
    * MCi/o: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28913
  * Electrical wirings
   * Coil resistances and inductances -> inductances shoulg refer the past data if coil did not change, or it will be measured again (Wasimi, 3/24(Monday morning)
    * MCo: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28668 -> MCo H4 looks high, it could be disconnection. It should be measured again (Wasimi, 3/24(Monday morning).
    *MCi/e: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28696 -> One of the MCi resistance is low, but low may has no problem. If it is high, it may have some disconnection.
   * Isolation of Wiring from coils to flanges(pico and mag-coil) -> MCi could not be accessed.
    * MCo: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28911 -> improved
    * MCe: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28910 -> improved
    * POM: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28914 -> this does not matter for the suspension.
   * Fixing on tables is tight and reliable?
  * Smooth Mag-coil motion and balance and TFs
   * balance can be adjusted after closing?
   * MCi: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28938
   * MCo: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28939
   * MCe: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28940 -> A.I. Peak of pitch shifted to higher frequency from result of Feb.2. Needs remote centering for the Oplev first (Ushiba).
Line 7: Line 28:
 * Alignment  * Mirror conditions(Y.Aso)
  * Clean around the center?
   * MCe has a spot near the center. But its influence is expected to be small.
   * Inspection: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28856
Line 9: Line 33:
 *  * Alignment(T.Akutsu, T.Ushiba, T.Yokozawa)
  * TEM00 flashing
   * https://klog.icrr.u-tokyo.ac.jp/osl/?r=28912
  * The IMC trans beam is the same as before?
   * https://klog.icrr.u-tokyo.ac.jp/osl/?r=28779
   * https://klog.icrr.u-tokyo.ac.jp/osl/?r=28839
   * https://klog.icrr.u-tokyo.ac.jp/osl/?r=28937
  * Beam positions on each mirror
   * They should be the same because the IMC trans was recovered in MCio?
   * How about on MCe? MCE tra QPD can be the reference.
  * QPD path and centering
  * Gaps between magnets and coils again
  * IP1/2 dynamic range check for the IMC injection?
  * Beam paths for IMC REFL.

 *Beam dump(T.Akutsu)
  * Beam shield reinstallation
   * https://klog.icrr.u-tokyo.ac.jp/osl/?r=28927
   * https://klog.icrr.u-tokyo.ac.jp/osl/?r=28926
  * Beam dumps were additionally added?
   * In basic, No. Relocation was done. https://klog.icrr.u-tokyo.ac.jp/osl/?r=28931 -> Inside of beam duct between PSL and iMC looks shining.

 * Vacuum, etc (N.Kimura, T.Uchiyama, S.Miyoki)
  * Cleaning
   * No dust inside, especially on the bottom? -> A.I. before closing.
  * Leak point was fastened tightly? -> A.I. when closing.
   * It will be done when the bellows are attached by Mirapro.
  * MCE trans flange rotation (the past activity is in https://klog.icrr.u-tokyo.ac.jp/osl/?r=28326) -> it will be done on Mon.
  * Lift-up tool check for bellows installation. (past accident https://klog.icrr.u-tokyo.ac.jp/osl/?r=28344)
  * Flange surface check to avoid leaking especially on GV_mcf
  * FFU stop for the MCE/MCREFL optical table and reconstruction of the window shield (MCE, MCF?). -> measurement of length of legs.
