A medical system for providing radiotherapy is disclosed. The system comprises a particle accelerator configured to produce a radiation beam and irradiate at least a part of a subject with the radiation beam. The particle accelerator comprises a plasma zone comprising or configured to receive a plasma, and at least one beam source configured to provide an excitation beam along an axis through the plasma zone. The medical system is configured to provide a plurality of charged particles in the plasma in a region that propagates through the plasma zone behind the excitation beam such that the plurality of charged particles are accelerated to produce a radiation beam comprising the plurality of charged particles with a broadband energy distribution, wherein: at least part or all of the energy distribution of the radiation beam is substantially exponential or power-law; the radiation beam delivers 75% or more of a dose of the charged particles at and below 2 g/cm; and/or the energy beam has an energy or energy distribution in the range from 10 eV to 10 MeV.

System for radiation therapy

A method of accelerating charged particles in a plasma and an associated plasma accelerator and electromagnetic radiation source, the method including creating a region of non-uniform electric field within the plasma which propagates through the plasma; using the non-uniform electric field to accelerate a first plurality of charged particles in the direction of propagation of the region of non-uniform electric field; and once the accelerating first plurality of charged particles have propagated part-way through the plasma: adding a second plurality of charged particles to the plasma, such that the second plurality of charged particles propagates through the plasma, the second plurality of charged particles create a local distortion in the non-uniform electric field experienced by the accelerating first plurality of charged particles, and the local distortion in the non-uniform electric field propagates through the plasma with the accelerating first plurality of charged particles; and the method also including using the local distortion in the non-uniform electric field to accelerate the first plurality of charged particles in the direction of propagation of the region of non-uniform electric field.
