In the development of compact terahertz radiation source, a table-top Cherenkov free-electron laser is proposed. The simplified model is consisted of a double-slap device, including a rectangular waveguide partially filled with two lined parellel dielectric slabs, driven by a 50 keV electron beam. The dispersion relation of such a model is investigated theoretically and the dispersion equation is solved numerically. With the help of a particle-in-cell simulation code, the mechanism of beam-wave interaction is carefully analized. According to those simulation results, we found the optimum parameters for this kind of device to operate at the terahertz wave region.
