High-Intensity Continuous Wave Slow Positron Source at Jefferson Lab

We present a novel concept of an electron linac-based slow positron source with projected intensity on the order of 10$^{\mathrm{10}}$ slow e$^{\mathrm{+}}$/s. The key components of this concept are a Continuous Wave (CW) electron beam, a rotating positron-production target, a synchronized raster/anti-raster, a transport channel, and extraction of positrons into a field-free area through a magnetic field terminator plug for moderation in a solid Neon moderator. The feasibility calculations were completed in the framework of GEANT4 simulation and OPERA-3D magnetic field calculation code.
