Statistical properties of cooperative emission of an ensemble of nonisochronous electrons–oscillators

Effect of shot noise and energy spread of particles on the statistical properties of cooperative emission of an ensemble of nonisochronous electrons–oscillators is analyzed. The dependences of the rootmean-square deviation of the peak radiation power and the autophasing time on the number of particles are determined in the absence of the energy spread. Even a minor energy spread of 4% leads to a decrease in the maximum possible power of cooperative emission.
