EFFECTS OF RANDOM ERRORS OF WIGGLER MAGNETIC FIELDS ON FEL GAIN AND OUTPUT
Based on Prof. Yumin's FEL longitudinal mode theory1, the small signal and exponential growth rates including the effect of wiggler magnetic field random errors have been obtained, and with SG-1 parameters, the scaling relation between exponential growth rate parameter g0 and magnetic field random error σ is provided. The results of linear theory have been verified by 3-D simulations.
