  • MFX photon dump sizing
  • CXI KB mirror shielding
    • Note Status.
  • Stopper location in XRT Alcove
    • Requirements to consider?
  • XRT collimators


Discussion:

  • MFX photon dump sizing
    • We have a preliminary size based on single pulse damage only but we need to know load from steady state
    • sheetrock burnthrough...or should we put layer of something else?
    • Concrete wall burnthrough calc for XPP. held up...we need help with assumptions/calc check
    • more info needed on KBs: substrate coating, focal length range
  • CXI KB mirror shielding
    • Note Status.
  • Stopper location in XRT Alcove
    • Requirements to consider?
    • check prefocusing lenses - we are removing. confirm.
    • stopped
  • XRT collimators
    • need upgraded L2Si version (2 locations)
    • overall XRT strategy? yiping? david? when?
      • air attenuation calculations need to be vetted - by whom??? Ask Yiping who he knows in the community.
        • latest study on tunneling through air...
        • someone from DESY can help?
        • is our gas attenuator going to work?
          • HXR atten needs upgrades to get to 2x pressure
