Production of polarized positrons through interaction of longitudinally polarized electrons with thin targets

Abstract

The production of polarized positrons by longitudinally polarized moderate energy (E = 50 MeV) electrons is proposed. The two-step process in a thin amorphous target e^- _long → γ_circ-pol. → e^- e^- _long. has been considered. For a target thickness of a tenth of the radiation length, the yield of positrons with energy above 25 MeV and polarization ∼0.5 may reach ∼10^-3 per initial electron.
