Plasma-fiber laser accelerator

Under the conditions presently elucidated, a laser electromagnetic wave trapped in a plasma fiber is noted to be capable of exciting a beat plasma wave possessing a flat phase front which propagates either at the speed of light, or any desired lower speed. In the unique case where the fiber defines a vacuum, it remains possible to generate a wave whose phase velocity is nearly that of light in the direction of particle propagation, in the case of a plasma slow wave structure, or in curved geometry. While the laser field parallel component is used to impart acceleration, the perpendicular component is either cancelled by the imposed static magnetic field force or directly employed in particle containment.
