Meeting Time and Place

Thursday October 14, 2021, 1pm Bluejeans https://bluejeans.com/465620466

  • Present - Hovanes Egiyan, Moskov Amaryan, Stephanie Worthington, Keith Harding, Igor Strakovsky, Tim Whitlatch, Mark Stevens, Johan Messchendorp

Agenda

Requirements and things to finalize

    • Cool tungsten plug to below temperature that affects lead (327°C)
    • 5 cm beam tube to PS and 6 cm to final target
    • Moveable out of beamline
    • Be 90% pure or better (price same for 98% pure)
    • Steel standoffs in bottom poly sheet
    • 1mm al window ok for collimator exit of target?
    • Beryllium sealing - ongoing discussions with RadCon
    • Existing 5cm lead and 1cm steel at collimator exit wall ok
    • 10 cm lead at both walls inside collimator cave
    • 10 cm distance from beryllium target to downstream vacuum window of.
    • Remove PS vacuum chamber and put in 6cm beampipe
    • 5 mm gap between beryllium and tungsten so heat does not transfer

Minutes

  • Calcs for heating of Tungsten and Beryllium not completed yet - Igor to email Johan
  • Eugene asked about temperature sensors - need rad hard and put on copper plates
  • Is 1mm aluminum window at exit of target ok? Should be

Action Items

  • Look at strength and deflection of base structure - Tim
  • Check to see if 6 cm pipe can fit through the shield wall at the collimator cave - Keith, Tim
  • Check overall dimensions of the collimator cave to compare to 3D model - Keith
  • Get Quote for 90% beryllium - Tim
  • Continue working on collimator cave 3D model - Keith
