Plasma Neutralization Models for Intense Ion Beam Transport in Plasma
Plasma neutralization of an intense ion pulse is of interest for many applications, including plasma lenses, heavy ion fusion, cosmic ray propagation, etc. An analytical electron fluid model has been developed based on the assumption of long charge bunches (lb>>rb). Theoretical predictions are compared with the results of calculations utilizing a particle-in-cell (PIC) code. The cold electron f...

متن کاملNonlinear Charge and Current Neutralization for an Ion Beam Pulse Propagating through a Background Plasma
This paper demonstrates the possibility of quasi-steadystate transport of a finite-length ion beam through a chamber filled with plasma of arbitrary density. We conclude that, in principle, partially-current-neutralized equilibria exist in the reference frame moving with the ion charge bunch for arbitrary ratio of beam density to plasma density. The electric and magnetic fields generated by the...
متن کاملExperimental Studies of Ion Beam Neutralization: Preliminary Results
A testing platform is designed to study ion beam neutralization in the mesothermal, collisionless region. In the experimental setup, argon neutrals were ionized in a microwave cavity and accelerated by a plasma lens system which was biased to 2500 V above the system ground. Electrons were boiled off from two hot tungsten filaments to neutralize the ion beam. The plasma is diagnosed using Langmu...
متن کامل“Electrodeless” Plasma Cathode for Neutralization of Ion Thrusters
Significant progress has been made in the characterization of the necessary parameters required to create an effective Radio Frequency (RF) plasma based electron source. Such a device has the promise of comparable current densities to and longer operational lifetimes than hollow cathodes. The operational lifetime of hollow cathodes is ultimately limited by cathode deterioration. RF sources prov...
