2.856-GHz Modulation of Conventional Triode Electron Gun
  For the generation of picosecond (< 100 ps) electron beam pulses, we studied the RF modulation of a conventional triode electron gun. The feasibility study for this scheme has been experimentally investigated by modulating a triode gun of the Y-824 cathode-grid (KG) structure provided by the CPI Eimac, with 2.856-GHz pulsed RF generated by a solid-state amplifier (SSA). In this paper, we present the methods and results of this investigation.
