Abstract
A method of accelerating charged particles using a laser pulse fired through a plasma channel contained in a capillary, wherein the plasma waveguide has deviations along its length that cause deviations in the plasma density contained therein, the deviations in plasma density acting to promote charged particle injection into a wake of a passing laser pulse. A radiation source based on a laser-driven plasma accelerator in a plasma waveguide in which the plasma waveguide and/or laser injection process is/are controlled so as to produce an undulating path for the laser pulse through the waveguide, the undulation exerting a periodic transverse force on charged particles being accelerated in the wake of the laser pulse, the resulting charged particle motion causing controlled emission of high frequency radiation pulses.
