Abstract : It was suggested that many important characteristics of a bunched relativistic electron beam might be determined by monitoring the Cerenkov radiation produced as the beam passes through or very close to a dielectric medium. This report describes an effort to produce stimulated Cerenkov radiation (SCR) in a dielectric slab using a bunched beam of 100 MEV electrons from a linear accelerator. Although the method used displayed only limited success, the results were consistent with previous work and further confirmed the basic ideas regarding SCR production. In conjunction with the experimental work performed, an analysis was conducted concerning the manner in which various electron charge distributions which might be used to describe how the electron bunches affect the Cerenkov radiation emitted by the beam. In principle, the results imply that proper monitoring of the Cerenkov radiation from a beam should allow one to deduce the total bunch charge and charge distribution.
