Abstract :
Conditions for the stable propagation of a pinched electron beam in low pressure gas (p ≈ .1-100 torr) are described. The observed window of good propagation around p ≈ 2 torr air is interpreted as the quenching of the two-stream mode by sufficiently high plasma density and collision frequency, and the simultaneous suppression of the resistive hose mode by sufficiently rapid generation of electrical conductivity from breakdown ionization.
