Abstract

An analysis of the Cherenkov maser instability operating with electron pulses is carried out. A model which can describe the effects of Coherent Spontaneous Emission (CSE) is derived. The results from this model are compared with previous work which neglect the effects of CSE. The model suggests that CSE can drive and significantly enhance superradiant emission from the electron pulses, offering a potential source of high intensity, short pulse radiation. This mechanism should also be present in other devices such as the Free Electron Laser.
