GENERATION OF POLARIZED POSITRONS

摘要

On the basis of a new method of generationg highly polarized positrons through pair-creation from γ-rays produced via Compton scattering of laser lights off electron beams, we have been carrying out proof-of-principle experiments and verified that the production rate of positrons was in good agreement with the theoretical prediction. This paper reports present status and future extension of the polarized positron project which has been pursued both at KEK and BNL.
