Abstract
An intense, pulsed, initially space‐charge‐neutral ion beam (100 kV, 1 kA, 600 nsec) has been propagated into a transversely oriented magnetic barrier. When the magnetic field is adjusted so that (ρiρe)1/2 ≪ a < ρi, a virtual anode is formed whose potential oscillates at ∼ωpi about a value near the ion accelerating potential, where a is the transverse beam dimension, ω pi is the ion plasma frequency, and ρe and ρi are the electron and ion gyroradii. This behavior is similar to that predicted by Poukey and Rostoker for virtual cathodes.Keywords
