Abstract

Based on Prof. Yumin's FEL longitudinal mode theory^[1], 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.
- magnetic field random error,
- exponential growth,
- saturated output
