Field-emission cathode gating for rf electron guns

Physical Review Special Topics. Accelerators and Beams, 2005
We present a novel method of combining the most desirable characteristics of thermionic-cathode and photocathode rf guns, using a field-emission cathode and multiple rf frequencies. Simulations indicate that extremely low-emittance beams (on the order of
