Methods for generating a multiple-energy X-ray pulse. A beam of electrons is generated with an electron gun and modulated prior to injection into an accelerating structure to achieve at least a first and specified beam current amplitude over the course of respective beam current temporal profiles. A radio frequency field is applied to the accelerating structure with a specified RF field amplitude and a specified RF temporal profile. The first and second specified beam current amplitudes are injected serially, each after a specified delay, in such a manner as to achieve at least two distinct endpoint energies of electrons accelerated within the accelerating structure during a course of a single RF-pulse. The beam of electrons is accelerated by the radio frequency field within the accelerating structure to produce accelerated electrons which impinge upon a target for generating Bremsstrahlung X-rays.

Presented systems and methods enable efficient and effective radiation planning and treatment, including accurate and convenient transmission of the radiation towards a tissue target. In one embodiment, a radiation system includes an electron gun, a bend magnet, a scan control component, and an electron beam entry angle control component. The electron gun is configured to generate electrons. The linear accelerator is configured to accelerate the electrons in an electron beam.

The electron beam entry angle control component is configured to control the entry angle of the electron beam.

A particle accelerator comprises a waveguide configured to accelerate a beam of electrons along an acceleration path. A diversion channel is configured to convey a beam of electrons along a diversion path.
