Abstract
Described herein is a medical linear accelerator including an accelerator target structure constructed of a material having a thickness of less than 0.2 radiation lengths, and an accelerator structure to receive an electromagnetic wave and generate an output therapy dose rate of electrons having a beam energy between 4-25 mega-electronvolts (MeV).
Claims7
A medical linear accelerator comprising:
- an electromagnetic wave source to receive a beam current of electrons and to generate an electromagnetic wave;
- an accelerator structure to receive the electromagnetic wave and to generate an output therapy dose rate of electrons having a beam energy between 4-25 mega-electronvolts (MeV), wherein the accelerator is a standing wave accelerator;
- and
- an accelerator target structure to receive the output dose of electrons comprised of:
- an x-ray emitting target to emit x-rays in response to receiving the output dose rate of electrons, wherein the x-ray emitting target is less than 0.2 radiation lengths.
