Abstract :
The effect of surface roughness on a moving electron bunch is considered by resorting to a model of a metallic structure with random perturbations on its surface. Based upon this model analytic expressions have been developed for both the average energy emitted per groove as well as for its standard-deviation. For a relativistic bunch both quantities are shown to be virtually independent of the momentum. Moreover, it has been found that the standard-deviation of the energy emitted per groove is proportional to the standard-deviation of the roughness parameter to the power of 1/4.
