Abstract
Methods, devices and systems for ultra-high dose radiotherapy are described that rely in-part on active switching control of a photoconductive switch when the accelerator is accelerating charged particles to produce output radiation at desired dose rates. One example method for producing output radiation in a flash radiotherapy system includes receiving, at a particle accelerator, a charged particle beam, where the particle accelerator system also includes a photoconductive switch coupled to the particle accelerator. The photoconductive switch can operate in a linear mode and includes a doped crystalline material that receives a voltage to establish an electric field across the crystalline material. The method includes producing a plurality of voltage pulses by the photoconductive switch in response to receiving light incident on the doped crystalline material, and accelerating the charged particles by the particle accelerator based on the plurality of voltage pulses to produce the output radiation beams for flash radiotherapy.
