摘要: We investigate the dynamics of a realization Fermi's relativistic acceleration mechanism that is charged test particle oscillating between two reflecting plates move stochastically. By allowing charge to radiate energy during each collision, we find main features system are (1) due radiation drag gained by bounded, and (2) radiated represents typical an on-off intermittent process, numerous continuous encounters with very small emission, interrupted short intense bursts radiation. This radiative process exhibits non-Gaussian statistical features.
