Discussion:

  • KB Mirror
    • Mirror FDR Feb. 15
    • Integrating bypass for future passthrough- rad safety
      • Matt Seaberg to review (he's out though)
    • Opened rev for Instrument PRD - added 2 new requirements
    • RP shielding
    • Thermal Enclosure
    • interfaces to RDS
    • multiplexing - how does this affect mirror motions?
  • Far hall configuration- final decision soon
    • Final decision this Friday?
    • BCR for new scope this week??
    • Latest : removable endstations and multiplexing is in scope, mode change/drift lifters is out
    • no drift lifters on MEC/CXI → we can predict limits for laser table placement
    • what can we do to reduce design constraints?
      • remove OH robot? add functionality back in a different way
      • move downstream optics even further downstream? in CXI? move walls ets?
        • LOC impact is minimal
        • WFS impacts - would need to reconsider calcs
      • RP impacts introduced to Shanjie last Monday
  • Diagnostic Station 1 in H4
    • preliminary vacuum analysis
      • still require level 1 processing
      • check mirror assumptions - pumping levels? outgassing?
      • prelim pressure level at mirror chamber 7e-10torr (used to be 5e-10 - no formal requirement)
      • adding apertures reduces to 6e-10
    • shielding structure
      • concepts under way
      • requirements from RP - directing us to mirror shielding note
        • need to translate into thicknesses for shielding
  • Common components

      • xpp hole will be 5mm - we can reuse guidance tube design (same as epix 10k)
      • mfx assumption was we needed slightly larger hole? needed for laser?
