[PEPPo] LCWS2024 Abstract - Update on Ce+BAF Positron Activities

[Andriy Ushakov]

Dear colleagues,

I will submit an abstract to the International Workshop on Future Linear Colliders (LCWS2024, July 8-11, 2024, University of Tokyo, Japan) - https://agenda.linearcollider.org/event/10134/

Please find below the draft of my abstract. Your comments/suggestions/corrections are welcome. Thank you.


Title: Update on Ce+BAF Positron Activities

Presenter: A. Ushakov

Abstract: A concept for a continuous wave (CW) polarized positron injector is being developed for the Continuous Electron Beam Accelerator Facility (CEBAF) at Jefferson Lab (Ce+BAF). This concept is based on positron beam generation by a high current polarized electron beam (1 mA, 120 MeV, >90% polarization) and on a water-cooled, 4 mm thick rotating tungsten target. An update on the Ce+BAF positron injector development activities will be presented, including the polarized electron source concept, simulations of positron beam generation, positron capture, calculations of energy deposited by beams in the target, capture magnets and standing wave cavities, and shielding design.


Best regards,
Andriy
