We describe a high intensity, low energy positron beam utilizing high specific activity 64Cu sources (870 Ci/g) produced in a reactor with high thermal neutron flux. Fast-to-slow moderation can be performed in a self moderation mode or with a transmission moderator. Slow positron rates up to 1.6 × 108 e+/s with a half life of 12.8 h are calculated. Up to 1.0 × 108 e+/s have been observed. New developments including a Ne moderator and an on-line isotope separation process are discussed.
