Radiative intermittent events during Fermi's stochastic acceleration

The rich dynamics of a relativistic model reproducing Fermi's stochastic acceleration was investigated. The model represented the first simple version that can be enriched by considering the dynamics in two- or in three-dimensional situations. The results for the one-dimensional case showed that when the charge is allowed to radiate during collisions with plates, its energy cannot increase without limits. the energy acquired by the particle is bounded and the radiated energy results in the realization of an on-off intermittent process.
