Meeting Info
We will meet on Wed (Mexico 9am, US 11am, France 5pm) Bluejeans: https://bluejeans.com/164307983 Code to start the meeting 2864
Agenda
- Presentations
- None scheduled (yet!)
- Updates
- Jiquan - large aperture cavity model for simulations
- Alicia - range of injector e- beam properties between 0L02 and NL; e.g. "ideal" specs for e+
- Dennis - range of CEBAF e- beam specs through the machine (linacs, arcs)
- Joe - testing GPT w/ spin tracking
- Eric/Sami - Improving positrons datas simulation from GEANT4, - Bibliography about focusing using array of quadrupoles magnets
Action Items
- (done) Joe share Sharepoint link so we can share files more readily
- Alicia post FY solenoid field models for both single and counter wound geometries on sharepoint
- Joe will do some more GPT spin testing, then Fanglei and Joe will compare Zgoubi and GPT spin tracking, we can use Wien and FY solenoid field models
- Alicia, Dennis, and Yves are working towards telling the group about desirable CEBAF e- beam parameters and possible limitations/acceptances
- Jiquan will suggest an RF cavity model with large aperture to use in the positron collection model
Future Meetings
- 2/24 - Bodgan - Concept for co-propagating e-/e+ beams at CEBAF
- TBD - Alicia - Primer on multi-objective genetic algorithm optimization (MOGA)
