Abstract
Abstract Linear particle accelerator of compact dimensions, intended for industrial or medical applications, comprising, in a vacuum enclosure, a particle source and an accelerating structure having an input coupler connected to a waveguide extending along the lateral and end walls of said accelerating structure, the waveguide portion located against the end wall of said structure being provided with two holes located along the beam path for the passage of accelerated particles; a hood arrangement groups all parts of the accelerating device (accelerator, UHF electromagnetic power source, voltage supplies).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
78 words
A linear particle accelerator comprising a vacuum tight enclosure in which is located a source producing a particle beam, an accelerating structure, means for loading said accelerating structure and injecting means to inject hyperfrequency energy in said structure, said injecting means comprising at least a folded waveguide entirely located within said enclosure, along said accelerating structure ; said structure being formed with a succession of cylindrical elements provided with notches , said waveguide being located within said notches.
Claim 2
Dependent Claim
78 words
