Abstract :
To achieve a narrow-band THz coherent Cherenkov radiation, the excited wakefield should be periodic and has a sin-like profile in time domain. Because the the wakefield pulse is similar to the driven bunch shape, the condition of narrow-band THz radiation is determined by a simple expression and verified by the commercial software CST PS.
