  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.
