Ions accelerating method for e.g. ion beam- and tumor therapy, involves accelerating ions penetrating titanium foils, at high energy, and decelerating ions that are not penetrating titanium foils, at
The method involves time-correlated high intensive laser impulse irradiation of thin titanium foils (2) and electrical fields between the titanium foils and behind electrons (5) separated from the titanium foils. Ions provided in the electrical fields and penetrating the titanium foils, of ion beams (1) are accelerated at high energy at a rear surface of the titanium foils by effect of the electrical fields. Ions that are not penetrating the titanium foils at a time point, are decelerated at smaller energy at a front side of the titanium foils. An independent claim is also included for a device for accelerating ions of ion beams by an electrical field.
