High gradient rf gun studies of CsBr photocathodes
CsBr photocathodes have 10 times higher quantum efficiency with only 3 times larger intrinsic transverse emittance than copper. They are robust and can withstand 80 MV/m fields without breaking down or emitting dark current. They can operate in 2×10^{−9} torr vacuum and survive exposure to air. Th...
