ABSTRACT:
The device according to the invention comprises a photocathode (1) illuminated by a luminous source (11) modulated at a high frequency F by an optical device (15) controlled at the frequency F, the optical device (15) being interposed between the luminous source and the photocathode. According to one aspect of the invention, the optical modulator (15) is controlled by a surrounding electromagnetic field at a high frequency F, in which the modulator is immersed. The electron gun device according to another aspect of the invention can be associated to a microwave circuit to obtain microwave oscillator or amplifier tubes. According to another aspect of the invention, the device supplies a pulsed electron beam for injection into particle accelerators.
