Physics of Neutralization of Intense High-Energy Ion Beam Pulses by Electrons

Abstract: Neutralization and focusing of intense charged particle beam pulses by electrons forms the basis for a wide range of applications to high energy accelerators and colliders, heavy ion fusion, and astrophysics. For example, for ballistic propagation of intense ion beam pulses, background plasma can be used to effectively neutralize the beam charge and current, so that the self-electric and self-magnetic fields do not affect the ballistic propagation of the beam. From the practical perspective of designing advanc… Show more

“…A ferroelectric plasma source (FEPS) is used to create plasma in the upstream portion of the drift region (Efthimion et al, 2009). Ferroelectric ceramics such as lead zirconium titanate (PZT) and barium titanate (BaTi0 3 ) have relative dielectric coefficients of several thousand and large polarization surface charge densities can be created when pulsed voltages are applied across pieces of these ceramics (Rosenman et al, 2000;Dunaevsky et al, 2001). If the electrode on one face of the ceramic is not solid, but rather a mesh or grid, the large non-compensated polarization surface charge density can create a strong tangential electric field at the vacuum-ceramic-electrode interface.…”

“…A source of neutralizing electrons localized near the beginning of the drift compression region does not provide adequate charge neutralization since the electrons pulled into the ion bunch compress together with the ion bunch, and are therefore heated, increasing their Debye shielding length and reducing the degree of neutralization. It is better to provide a source of neutralizing electrons throughout the drift compression region (Kaganovich et al, 2010). Therefore, plasma sources have been developed for both NDCX-I and NDCX-II to fill the drift compression region with dense plasma that acts as the source of neutralizing electrons.…”

“…Filaments, on the other hand, are easier to install and control, however, experiments have found multiple challenges in their use in the ion beam neutralization. For example, the rate of neutralization is affected by the energy and location of the electron source relative to the ion beam [10,11]. Additionally, in recent numerical works by Lan and Kaganovich [10,12], electrostatic-solitary-waves (ESWs), also known as electron solitons, were observed to form when electrons were injected into a 2D ion beam via a filament source.…”
