Meeting Time and Place

Tuesday January 16, 2024, 1pm Hall D Counting House

Invited - Hovanes Egiyan, Stephanie Worthington, Keith Harding, Pavel Degtiarenko, Tim Whitlatch, Eugene Chudakov, Josh Ballard

State goals of meetings (Tim/Hovanes)
Review Pavel's current design parameters for the entire CPT (Pavel)
- Pavel Presentation media:Conceptual Design of CPS Eng.Mtg. 01-16-24.pdf
Magnet update (Josh)
Develop path forward for final design (meetings/schedule etc...) (all)

Discussed background of the project and the goal of getting the design completed in a little over a year
Pavel presented the current conceptual design based on his analysis
- Copper radiator
  - Operate remotely
  - 300 micron repeatability
  - 2 thicknesses plus blank
  - 2cm diameter?
  - rad hard materials (no encoder)
  - maybe proximity switch/LVDT for positions
- Need to develop a complete thermal model as design progresses
- Use of a steel core for support
- overall alignment of magnet and radiator to be within a few hundred microns
- Ability to move the assembly (with out magnets) completely out of the beam to the north wall
- Ability to crane or forklift the core out during decommissioning
- Total weight approximately 90 tonnes
- Need temperature sensors on copper, lead and steel
- Need to fine tune the thermal calcs on copper absorber
- Need water temperature and flow meters
- US magnet to be designed to 2x current plus 10%
- Need tungsten block to absorb the electron beam on magnet failure
- Consult with Hall C folks on their design experience of a CPS

Pavel to check into exporting his model in a compatible format for NX ( Open Scad etc...
Stephanie to look into importable files from her end
Tim to provide stp file from ANSYS for Designers
Tim to setup bi-weekly meetings
Tim to set up and Engineer/Designer detailed meeting
