Stability and Transport Properties of an Intense Ion Beam Propagating Through an Alternating-gradient Focusing Lattice
Authors: W.W. Lee, Q. Qian, and R. Davidson
Stability and transport properties of an intense ion beam propagating through an alteranating-gradient focusing lattice with initial Kapchinskij-Vladimirskij (KV) distribution are studied using newly-developed perturbative (df) particle simulation techniques. Stability properties are investigated over a wide range of beam current and focusing field strength. In the unstable region, large-amplitude density perturbations with low azimuthal harmonic numbers, concentrated near the beam surface are observed. Their nonlinear consequences are discussed.
