Abstract
The disclosure relates to linear proton accelerators. A proton accelerator is made by using travelling waves with magnetic coupling to accelerate the protons in forward or backward mode and in fundamental or harmonic mode. In particular, an accelerator for medical use, giving energy of 250 MeV, uses three accelerator structures positioned in series and working with travelling waves of the forward, harmonic mode type for a first structure, of the backward harmonic type for a second structure and of the backward fundamental mode type for a third structure. Furthermore, the microwave energy at 3,000 megahertz is given by a single klystron. This results in a considerably reduced length of the accelerator and a cost that makes it capable of being used for therapeutic applications.
