<p class="MsoNormal"><span style="font-size:12.0pt">Abstract: A concept for a continuous wave (CW) polarized positron injector is being developed for the Continuous Electron Beam Accelerator Facility (CEBAF) at Jefferson Lab (Ce+BAF). This concept is based
on positron beam generation by a high current polarized electron beam (1 mA, 120 MeV, >90% polarization) and on a water-cooled, 4 mm thick rotating tungsten target. An update on the Ce+BAF positron injector development activities will be presented, including
the polarized electron source concept, simulations of positron beam generation, positron capture, calculations of energy deposited by beams in the target, capture magnets and standing wave cavities, and shielding design.<o:p></o:p></span></p>
