Should we make it possible to align SRM even if it has less reflectivity for RSE? | - Where is the reflected beam from SRM? When misaligned, should it hit the mid-size baffle on PR2 or other?

(1) Suspension health check for PRM/2/3/ BS SRM/2/3 IMMT1/2: (Takahashi-san and Ushiba-kun and selected people)
A01: Cable check:
A02: Porality Check
A03: Rubbing Check
A04: Range and Calibration (Actuators performance check)
A05: Watchdog Settings
A06: Height Setting (Mirror Position) -> Beam paths
A08: LVDT Calibration and performance
A09: Spectrum
A10: Transfer Function
A11: Traverser performance and safety protection
(2)Oplev Check for PRM/2/3/ BS SRM/2/3, except for inevitably removed poles/optics for vacuum parts setting. (Yokozawa-kun)
Beam Path Clearance
QPD centering
Calibration
PYL Separation(after pumping?)
Spectrum health
Oplev beam's stray light influence
Covering
(3)Mid-size Baffles (Akutsu-kun and his selected persons)
Positioning accuracy
(4)Beam Path (Ushiba-kun, Tanaka-kun?, Hirose-san?)
Main beam - IR beam hit and through around the center (or acceptable area) of optics from inside IFI tank -> SRM.
GR beam - GR beam hit and through around the center (or acceptable area) of optics?
- (assuming GR beam on POP/POS also pass through around the center (or acceptable area) of optics)
IR from the misaligned PRM - Does it hit on the Dumper? - The misaligned position repeatability is good or well controlled by oplev/something?
Relative positions btw Mid-size baffles and IR/GR.
AR-SRM reflection beam control - Where is the reflected beam from SRM? When misaligned, should it hit the mid-size baffle on PR2 or other? Should we make it possible to align SRM even if it has less reflectivity for RSE?
(5)IFI-IMMT tank
Stray light mitigation(Akutus-kun and selected persons) - The predicted stray beams are dumped? - Is there any missing stray beam paths?
ISS beam/CWP reflection beam extracting (??) - the beam paths are clear? - The beams hit around the center of windows? - The reflected beams on the windows are dumped?
(The IFI new poles seem to be dangerous due to the vibration made by drilling.)
Beam dumper(Akutsu-kun and selected pesrons) - Does the thermometer works?
(6)Vacuum system (Kimura-san / Uchiyama-kun and their selected persons)
Numbering for all ports.
Check the flange seal surface condition.
Decide where the elastomer/Metal gasket will be used.
Top hat seal surface check for SRM/2/3 BS PRM/2/3.
ICF152 flange preparation for the new reducer flanges at SRM/PRM.
Check dust/fungus in stocked tubes/bellows.
(7)Cleanness of Mirrors HR/AR
FC was done for all mirrors' HR/AR, except for OMC Typ-C mirrors.
Check the surfaces and inside again before closing, and blow/absorb as much as possible if you find anything.
(8)Vacuum tank cleaning
In Basic, the cleaning was done after FC. Check inside again and clean just before closing if you find something.
(9) MICH performance
Can we obtain MICH fringe with the aligned ITMX/Y and BS at the REFL PD? Should we lock MICH using REFL PD?
(10)misc
Put Si plate for the dust monitoring? (Si plates/holders were bought well before.)
Mirror View Camera Should we recognize the view image under the bright condition? (Which parts can be seen where in the image.)
Are there any leaning materials on the suspension support frame!?
Are there any stressful cablings on flanges?
