Beam halos are studied in a dynamical stochastic model with enhanced transverse dispersion and transverse emittance growth. We explore the effects of non-Gaussian noises with larger variances and possible jumps. The stationary distribution of Ornstein-Uhlenbeck processes with particular L´evy noises is then calculated. For Student processes the asymptotic spatial behavior coincides with that found in other independent numerical halo models.

Abstract
Beam halos are studied in a dynamical stochastic model with enhanced transverse dispersion and transverse emittance growth. We explore the effects of non-Gaussian noises with larger variances and possible jumps. The stationary distribution of Ornstein-Uhlenbeck processes with particular L´evy noises is then calculated. For Student processes the asymptotic spatial behavior coincides with that found in other independent numerical halo models.File in questo prodotto:
