Phys. Rev. Lett. 85, 4514–4517 (2000)Energy Transfer in Nonequilibrium Space-Charge-Dominated BeamsSee Also: Erratum Received 31 May 2000; published in the issue dated 20 November 2000 Space-charge modes similar to those observed in recent experiments appear in simulations of nonequilibrium charged particle beams with anisotropy. The modes couple degrees of freedom, causing energy transfer and equipartitioning without halo formation in just a few betatron wavelengths. The rate depends on a single free parameter quantifying the space-charge intensity of the final state. Traditional stability analyses are shown not to apply to high-intensity laboratory beams originating with a large perturbation from equilibrium. © 2000 The American Physical Society URL:
