Abstract
The invention relates to an electron gun for a linear accelerator, able to supply a modulated electronic current for injection into an accelerating structure. Such an electron gun comprises a cavity resonator in which a cathode and a grid define a grid--cathode space, on which is closed said cavity resonator. An electromagnetic wave injected into said cavity resonator defines, with the grid and the cathode, an alternating potential difference by which the electronic current is modulated. The invention more particularly applies to industrial irradiation machines.
