  • Generator for generating high energy electrons in a gas
    Patent number: 4916355
    Abstract: An X-ray generator comprises an anode (4) and a cathode (10) disposed in an enclosure (2) under low helium pressure and powered by an electric pulse generator (20) providing sufficient voltage in order to generate runaway electrons. The emission face of the cathode is a section of an emission plate (10) constituted by a carbon felt whose fibers have a privileged orientation perpendicular to said face in order to encourage the emission of electrons from said face. The invention is particularly applicable to pre-ionizing the discharge chamber of a gas laser.
