Initial operation of a 17 GHz RF photocathode electron gun has been achieved at MIT. This is the first photocathode electron gun to operate at a frequency above 2.856 GHz. Such electron guns have the potential for achieving record high values of electron beam quality. The 1.5 cell, p-mode, copper cavity was tested with 5-10 MW, 100 ns, 17.145 GHz pulses from a klystron amplifier built by Haimson Research Corp. Conditioning resulted in a maximum surface field of 250 MV/m. Dark current of 0.5 mAdoi:10.1109/pac.1997.752733 fatcat:lt763f4wcfhq3e6mtmemgmunpq
