March 26, 2024 KLONG CPS Design Meeting
From GlueXWiki
Meeting Time and Place
Tuesday, March 26, 2024, 1pm Hall D Counting House
- Invited - Hovanes Egiyan, Stephanie Worthington, Keith Harding, Pavel Degtiarenko, Tim Whitlatch, Eugene Chudakov, Josh Ballard
Agenda
- Review minutes from last meeting https://halldweb.jlab.org/wiki/index.php/February_27,_2024_KLONG_CPS_Design_Meeting
- Review new basic 3D model and compare to Pavel's model (Pavel, Keith)
- Copper Absorber updated media:Copper absorber.pdf
- Tagger Hall Layout (Stephanie/Keith)
- De-gaussing of Tagger magnet (all)
- Run test with an existing dipole magnet at magnet measurement (Tim, Joe Meyers)
- Magnet update (Josh/Stephanie) media:CPS Magnet Design.pdf
Minutes
- Reviewed minutes from last meeting
- Discussed progress on 3D model
- Discussed possibility of removing borated poly layer from the back side when moving CPS out of beamline
- Pavel will check radiation levels
- It will make more clearance for GlueX reinstall
- Poly can be attached outside of support frame
- current model shows using cartridges from the FCAL for support and alignment set at 33% in Z. Need to move them out slightly
- Ok to have a gap upstream of copper absorber for water lines - total shielding thickness still needed
- On downstream end, keep center Cu/W inner block up against the absorber (inside of the water lines) OK for gap outside this
- Currently the copper absorber model is 1.67 cm below beam center, we will move to 2 cm below
- Cu absorber water channels modified to .5 in holes x8. Keith/Josh will get Pavel a usable 3D model of the modified absorber to import into Fluka
- Discussed possibility of removing borated poly layer from the back side when moving CPS out of beamline
- Need to set the center of the magnet poles 2cm below beamline
- Magnet pole gap is clear of all materials, Cu/W can fill in coil regions
- Get Z dimensions for all components
Action Items
- Pavel to check radiation levels to see if poly can be removed after experiment
- Tim to supply Z locations for adjustment cartridges
- Keith to update 3D model with changes discussed including move magnet down 2cm and absorber to 2cm below beamline
- Get absorber 3D model to Pavel - Keith/Josh
