Ion Beam Neutralization by a Tenuous Background Plasma ---- Inventors Igor Kaganovich and William Berdanier

The neutralization and focusing of intense charged particle beam pulses by electrons form the basis for a wide range of applications for accelerators, heavy ion fusion, and astrophysics. This invention shows that for intense ion beam pulses, a background plasma with a low relative density can be used to effectively neutralize the beam charge and beam current, thereby neutralizing the self-fields and avoiding some of instabilities associated with beam-plasma interaction.
