Simulation of electron acceleration in an ondulator

Electron and laser beam interaction in the field of a profiled ondulator is theoretically calculated. Electron capture in the acceleration regime is shown to take place when complying with the conditions of interaction synchronism. Expressions for acceleration rate and dimensions of the phase stability range are obtained. The results of numerical simulation of ∼ 60 MeV electron acceleration for Nd- and Co2-lasers with account of initial energy spread of an electron beam are presented
