Patent ID: 8598814

Claim:
A method for pulsed operation of a linear accelerator, the method comprising: generating pulses of charged particles, the generating comprising emitting particles by a particle source and accelerating, in an accelerator device that comprises a plurality of linked cavity resonators, the particles, the accelerator device being supplied with energy by an energy supply unit; adjusting an impedance of the accelerator device to the energy supply unit such that energy coupled into the accelerator device diminishes as a number of the particles emitted by the particle source per pulse increases; and changing a loading, wherein the supplying of the energy for the accelerator device is held constant, the changing of the loading comprising changing the loading such that energy of the particles is changed solely by varying the number of the particles emitted by the particle source per pulse, wherein the impedance is adjusted, and the loading is changed, such that effects of the adjusting and effects of the changing reinforce each other.
