Abstract The present invention relates to methods for acceleration of ions in linear accelerator and to a linear accelerator realizing this method. The method for the acceleration of ions in linear accelerators consisting of a cavity resonator 1 and drift tubes 2 employing a standing r.f. electromagnetic wave, according to the invention, is characterized in that the resonator is excited in the E011 mode enabling the energy of the accelerated-ion beam to be controlled continuously by establishing a region with a uniform distrubution of the accelerating field and by varying the extent of that tregion. This method can be realized by a linear accelerator comprising a cavity resonator 1 with drift tubes 2; tuners 3 arranged on the side wall of the resonator 1; an additional tuning means made in the form of a conducting post 4 installed in an end wall of the resonator 1 near its side wall parallel with the axis of the resonator and capable of being moved along that axis.
A method for the acceleration of ions in linear accelerators of the cavity resonator type with drift tubes, employing a standing r.f. electromagnetic wave in the E011 mode, enabling the energy of the accelerated-ion beam to be controlled continuously by establishing a region with a uniform distribution of the accelerating field and by varying the extent of that region.
