DC Acceleration of Charged Particles by an Electrostatic Wave Propagating Obliquely to a Magnetic Field B^^^ _0

Abstract

A charged particle trapped in an electrostatic wave is accelerated in the plane perpendicular to the wave vector k. It is found that there is an optimum angle theta = theta/sub m/ at which the particle gains a maximum energy which is about four times larger than that at theta = ..pi../2, theta being the angle between k and the magnetic field.
