Based on a femtosecond linear accelerator, here we present a study of the use of a groove guide as the FEL interaction structure for high power FEL experiment. The transmission and attenuation characteristics of the dominant mode in the groove guide are discussed. And the coherent spontaneous emission in the FEL is simulated by Gover theory.
