IMC Ecovery(20240322)

Suspensions(R.Takahashi)
- Electrical wirings
  - Coil resistances and inductances
    - MCo: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28668
    - MCi/e: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28696
  - Isolation of Wiring from coils to flanges(pico and mag-coil)
  - Fixing on tables is tight and reliable?
- Mechanical Motion
  - Smooth pico motion and its default position
  - Smooth Mag-coil motion and balance and TFs
    - balance can be adjusted after closing?
    - Health MCo: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28890
    - Health MCi: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28889
    - Health MCe: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28915
  - Gaps between magnets and coils
  - Gaps between EQ stoppers and mirrors
    - MCe: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28915
    - MCi/o: https://klog.icrr.u-tokyo.ac.jp/osl/?r=28913
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
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
- 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 damping(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 dampers were additionally added?
Vacuum, etc (N.Kimura, T.Uchiyama, S.Miyoki)
- Cleaning
  - No dust inside, especially on the bottom?
- Leak point was fastened tightly?
  - 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)
- 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?).
