Abstract
The present invention relates to an hyperfrequency resonant system designed to accelerate a beam of charged particles, and comprising at least a first resonant cavity (or a group of resonant cavities similar to this first cavity) tuned at a fundamental frequency F and excited by means of an external electro-magnetic energy source and a resonant element which is, for example, a second resonant cavity tuned at harmonic frequency 2F and excited by means of the bunched particle beams. The invention is applicable, for example, to particle accelerators of the "microtron" kind.
Claims5
A hyperfrequency resonant system for producing a charged electron beam in a microtron accelerator, said particle beam having substantially circular paths whose radii increase with each transit of said beam through said resonant system, said resonant system which is disposed along said beam comprising at least a plurality of first resonant cavities fixed with respect to each other tuned at a fundamental frequency F and excited at said frequency F by means of an external electromagnetic energy source, said first resonant cavity being disposed along the beam axis associated with a resonant element tuned to the harmonic frequency 2F and disposed along said beam axis and fixed with respect to said first cavities, said resonant element being excited at frequency 2F by means of said beam, the particles of which are bunched after the first passage of said beam through said resonant system.
