Abstract :
A model of two electron-beams Smith-Purcell free-electron laser (SP-FEL) is presented in this paper. The dispersion relation for such a system is obtained employing linear fluid theory. The dispersion curves and growth rate are investigated through the numerical solution. The growth rate is considerable enhancement at the synchronous point of two-stream and electromagnetic wave.
