Abstract

A linear particle accelerating structure is provided for accelerating protons using radio frequency (RF), radiation, the structure comprising at least two coupled resonant cavity units. Each resonant cavity unit comprising a corresponding resonant cavity with an input port and an output port for a beam of protons; and an RF input to receive an RF signal; an RF phase shifter to control the phase of the RF signal. The particle accelerating structure further comprises at least one RF phase shifter to adjust, in one or more of the respective cavities, a phase of the RF signal to expose the protons to an accelerating portion of the electric field for a first duration and to expose the protons to a decelerating portion of the electric field for a second duration, wherein the first duration is greater than the second duration and greater than zero and wherein the second duration is greater than or equal to zero.
