Description
While a polarized positron beam offers a significant probe at a collider facility, it is also an important tool for the study of nucleon structure at a fixed target facility such as Jefferson Lab. For instance, a model independent extraction of the generalized parton distributions from
deeply virtual Compton scattering requires both polarized electrons and polarized positrons. The feasibility of a polarized positron source based upon the CEBAF polarized electron source will be presented. In this scheme, the longitudinal polarization of the electron beam is transfered to positrons via intermediate elliptically polarized photons generated in a suitable conversion target via electron polarized bremsstralhung. This talk will discuss recent developments and status of a suitable polarized electron source, and progress for the characterization of a polarized positron source for a hadronic physics program.
