| Abstract: | We present a design study of a free electron laser (FEL) oscillator for high power THz source experiments on the basis of the Shanghai femtosecond accelerator device. A circular groove guide is used as a new interaction structure. Plane metal meshes are used as upstream and downstream mirrors of the resonator.The general design parameters are presented. We analyzed the spontaneous emission and stimulated emission in the oscillator using these parameters. |
