Meeting Time and Place
Thursday February 17, 2022, 1pm
Zoom https://jlab-org.zoomgov.com/j/1611857466?pwd=VEZndTZzdDdNOUdJU3NxblRLcVoxdz09&from=addon
- Invited - Hovanes Egiyan, Stephanie Worthington, Keith Harding, Igor Strakovsky, Tim Whitlatch, Vitaly Baturin,
Mikhail Bashkanov, Anthony Palazzo, Eugene Chudakov, Mark Stevens
Agenda
Phase II is the section downstream of the collimator cave shield wall through the liquid target
- Minutes from last meeting https://halldweb.jlab.org/wiki/index.php/January_20_2022_KLONG_Phase_II_Design_Meeting
- Platform load rating is 17000 lbs (7.7 tonnes)- will be good to hold MRI
- 3D model layout progress
- FLUKA model updates
Requirements and things to finalize
- 6 cm beam tube through Pair Spec magnet to cryo target (1.5 - 2mm wall thickness ok)
- Remove PS vacuum chamber and put in 6cm beampipe
- Use existing Cryo target cart
- 90 l/min LCW needed
- Flux monitor downstream edge is 4m from PS magnet center
- Requirements for beamline downstream of collimator cave media:Igor's_layout.pdf
- Mikhail Flux Monitor Presentation media:Fluxmonitor_2022.pdf
- link to KLF wiki https://wiki.jlab.org/klproject/index.php/Main_Page
- Link to Hall A/C CPS talk - https://userweb.jlab.org/~gabriel/gn_cps_jlab_02_18_2022.pdf
