Meeting Time and Place

Thursday December 09, 2021, 1pm Bluejeans https://bluejeans.com/465620466

  • Present - Hovanes Egiyan, Stephanie Worthington, Keith Harding, Igor Strakovsky, Tim Whitlatch, Mark Stevens, Vitaly

Agenda

Requirements and things to finalize

    • Cool tungsten plug to below temperature that affects lead (327°C)
    • 5 cm beam tube through sweep magnet 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

  • Vitaly presented power absorption calculations
  • Discussed future designs

Action Items

  • Vitaly to provide finer resolution of power absorption near beamline
  • Tim to use Vitaly power absorption to calculate temperatures of Beryllium and Tungsten
  • Look for temp sensors - Keith/Tim
  • Continue working on drawing package - Keith
