Abstract
This gun comprises a cathode K, a grid G, and an anode A between which the applied voltages are radio-frequency voltages. The cathode is disposed on the central conductor of a coaxial cavity, facing said grid terminating said cavity. Said cavity is terminated at the other end by a short-circuit and includes a coaxial branch line so as to resonate at two frequencies F.sub.1 and F.sub.2 multiple of f.sub.0, whose beating induces a radio-frequency grid-cathode voltage. Said grid terminates another coaxial cavity whose central conductor is hollow and whose end facing said grid forms the anode. said other coaxial cavity resonator is excited and resonates at a frequency F.sub.0 multiple of f.sub.0, which induces a radio-frequency anode-grid voltage. A proper selection of the frequencies F.sub.0, F.sub.1, F.sub.2 allows to obtain electrons bunches of very short duration.
