Plasma based cross-field particle acceleration with high power microwave

;Electron acceleration based on the V-p x B acceleration (or the cross-field acceleration) scheme. which has a static magnetic field across the wave propagation direction, is reviewed, specifically the electron linear accelerator using a transverse mode of an EMW is introduced. Penetration and ducting of an intense microwave into overdense plasma are discussed, which show an experimental simulation and precise understanding of the concept of an optical guiding in the laser wakefield accelerator. Coherent radiation of ultrashort microwave pulse by DC-AC radiation conversion scheme has been demonstrated with use of CO2 laser and array of capacitors. This scheme is based on the mechanism of photon acceleration. (C) 1998 Published by Elsevier Science B.V. All rights reserved.
