IMC recovery(20240322)
- 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.
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.
Gaps between magnets and coils -> MCo uppper is the minimum, but this is the best effort.
- Gaps between EQ stoppers and mirrors
- Smooth pico motion and its default position
- Electrical wirings
- Coil resistances and inductances
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).
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)
- Fixing on tables is tight and reliable?
- Coil resistances and inductances
- Smooth Mag-coil motion and balance and TFs
- balance can be adjusted after closing?
- Mechanical Motion
- 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
- Clean around the center?
- Alignment(T.Akutsu, T.Ushiba, T.Yokozawa)
- TEM00 flashing
- The IMC trans beam is the same as before?
- 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
- Beam dumps were additionally added?
In basic, No. Relocation was done. https://klog.icrr.u-tokyo.ac.jp/osl/?r=28931
- 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?).
- Cleaning
one of templates for IMC closing by Akutsu-kun in 2021.
