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
- Minutes from last meeting https://halldweb.jlab.org/wiki/index.php/September_02,_2021_KLONG_Design_Meeting
- Preliminary 3D Model
- Collimator Cave Beamline
- Heat absorbed by Be and Tungsten (.6kw and 6Kw respectively)Johan study?
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 and Action Items
- need to look at thermal conductivity of whatever beryllium alloy is used
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
