Numerical Simulation of High Energy Light Ion Beam Flow through a Foilless Diode.
Abstract
A numerical and theoretical study is reported which treats the effects upon a 500 ke V, hollow electron beam in a foilless diode along the centerline of which has been injected a beam of 30 Me V protons. Specifically, the results of simulations of three, separate equilibrium diode states (for electron-only, 1 kA of protons, and 5 kA of protons) are reported. The computational findings are compared to rough, theoretical predictions and very good agreements is observed. The conclusion may be drawn that, for the diode parameters studied, a 1 kA beam of 30 Me V protons does not seriously disrupt the electron beam. On the other hand, a 5 kA proton beam not only radically alters the REB (Relativistic Electron Beam) characteristics but also itself falls prey to strong, radial ballooning. (Author)
