Meeting Time and Place

Thursday June 10, 2021, 1pm Bluejeans https://bluejeans.com/465620466

  • Present - Eugene Chudakov, Hovanes Egiyan, Moskov Amaryan, Stephanie Worthington, Keith Harding, Igor Strakovsky, Desiree Ahrens, Tim Whitlatch

Agenda

  • Requirements:
    • Collimator cave

Minutes and Action Items

  • Everyone introduced themselves.
    Igor and and Eugene briefly presented the problem of what needs to be done for the kaon production target (KPT).
  • Igor went through his slides to describe the KPT conceptual design.
  • Eugene had a few questions and comments.
    1. It would be helpful to have a single document, relatively brief, showing all the relevant for designers KPT dimensions.
      It was agreed that Tim, Stephanie and Keith will draw their own sketch based on Igor's presentations, and will request the missing numbers.
    2. Would it be helpful to have a beam pipe (steel) before the tungsten plug?
      This has not been considered yet.
    3. How do we hold the beryllium target in front of the tungsten plug?
      • Attaching it to the plug means that it will get heated by the plug.
      • One may consider a small gap between the target and W-plug and relay on the air convection.
      • Either way, one needs to estimate the temperature of the beryllium.
      • Igor would like to know what options there are for which one may perform simulations.
    4. Eugene would like the KLF collaboration to produce a heat depositions profile versus z for the lead, beryllium and the tungsten plug.
      • Moskov agreed.
      • Currently Igor's program does not do that.
  • Hovanes asked Tim if it would be easier to have a rectangular design for the KPT shielding rather than a barrel shape.
    Eugene thinks it can be some kind of combination to simplify the mechanical design and to reduce the amount of lead used.
    Tim has been thinking about it, but so far has no preference.
  • We agreed to meet every two weeks at the same time, until further notice.

Action Items

  1. Go over the existing sketch and identify missing dimensions (designers and Igor).
  2. Determine the heat deposition profile (KLF).
  3. Options for holding the Be target in place. (designers)
  4. Shape of the KPT shielding: barrel vs rectangular. (designers)
