THE MOTION OF CHARGED PARTICLES IN A RADIOFREQUENCY FIELD.

Abstract

The collision-free motion of charged particles is found for the case of an electrodeless ring discharge at breakdown. This radiofrequency field configuration consists of a spatially constant axial magnetic field and an azimuthal electric field which varies linearly with distance from the discharge tube axis. An analytic solution is obtained for the equations of motion. It is found that stable (time-bounded) solutions exist for certain values of the ratio of cyclotron frequency to applied field frequency. The motion is contained within the discharge tube, for arbitrary initial position, only for those particles which start from rest. Protons and heavier particles experience little motion in this environment. Electron trajectories are presented and discussed for a variety of initial conditions and magnetic field strengths.
