Plasma Channel Dynamics Created by High-Current Relativistic Electron Beam When Being Distributed in Gaseous Media of Various Types
Abstract
Experimental results of determination of plasma channel dynamics created by high-current beam (energy of electrons E(sub e) =1,1 x 10(exp 6) eV, beam current I(sub b)=2,4 x 10(exp 4) A, with pulse duration t=60 x 10(exp -9) c.) in gases: helium (He), nitrogen (N(sub 2)), neon (Ne), Air (Air),argon (Ar), krypton (Kr), xenon (Xe), humid air (Air:water) at pressure from 1 to 760 Tor are presented. It is showed that in gases with low value relation of collision rate v to ionization rate u; (v/lu <1) electron beam forms wide plasma channel of high conductivity: R(sub b)/R(sub p)<l (where R(sub b)- beam radius, R(sub p) plasma channel radius), which provides suppression of large-scale resistive hose instability (RHI).
