Description

Here, we present a compact injector design within the LERF vault, which would serve both the 22 GeV CEBAF and the positron program; being synergistic with electron source required to produce positrons for Ce+BAF. The injector complex is arranged in a racetrack configuration hosting three, C-75 cryomodules, each providing 71 MeV energy boost. Starting with a ~10 MeV photo-injector, a final energy of 650 MeV will be reached in three re-circulation passes. The injector offers a flexibility to extracting 1-pass, 2-pass or 3-pass energy electrons, as needed for positron production.
