Center for Injectors and Sources

CIS members are (l to r) Jim Clark, Matt Poelker (Group Leader), Steve Covert, Phil Adderley, Riad Suleiman, John Hansknecht, Marcy Stutzman, Joe Grames.

Our group develops and maintains the highly spin-polarized (>85%) electron photo-injector of the CEBAF accelerator at Jefferson Lab based upon photoemission from strained-superlattice gallium arsenide photocathodes. Our group is involved in the associated R&D of very high voltage DC guns, high power RF synchronized lasers, extreme high vacuum, novel photocathode materials and electron beam polarimetry.
