Jefferson Lab is proposing to add positron beams to the 12 GeV Continuous Electron Beam
Accelerator Facility (CEBAF). A team of accelerator, physics and engineering staff have been
developing the concept for the generation, production and delivery of Continuous (CW) polarized
positron beams to the experimental halls, up to the full 12 GeV. A layout of the proposed concept
will be shown. We will report on the ongoing efforts in the positron generation and capture, target
design, beam transport and expected properties of the e+ beam on the experimental targets at 12
GeV.
