Abstract

Intense charged particle beams in plasmas are subject to current limitation for single beam propagation. The limiting mechanism is excessive self-focusing due to net current and space-charge overneutralization effects. A nearly constant minimum plasma impedance of ∼30 Ω is presented to beams with Lorentz factors γ≳1.1.
