Bluejeans: https://bluejeans.com/164307983
Code to start the meeting 2864

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

(done) Joe share Sharepoint link so we can easily share files with one another, remotely too
Sami and Eric continue developing polarized cross-section and Geant4 benchmarking, and studies
Cristhian is quantifying magnetization and distribution of positrons in solenoid field
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, post on sharepoint
