1. An apparatus for generating electron radiation upon impingement of an electron beam on a scattering foil, said apparatus comprising:

  • accelerator means including an electron injector for emitting injector pulses, an electron gun for receiving said injector pulses, a waveguide for receiving electrons from said electron injector and emitting electrons, and a high frequency source for supplying RF signals for the generation of an electric field for accelerating said electrons in said waveguide and generating said electron beam;

    sensing means coupled to said electron injector for sensing said injector pulses and generating sensing signals having a characteristic representative of the amplitude of said injector pulses; and

    inhibiting means coupled to said accelerator means and responsive to said sensing signals for inhibiting the generation of said electron beam if said sensing signal characteristic exceeds a predetermined reference value assigned to a predetermined intensity level.
