Abstract
It is proposed that electromagnetic radiation of a speci'
fied frequency can be produced by stimulated Cerenkov
radiation in a dielectric resonator excited by a relativistic
electron beam. The frequency generated depends upon
the energv of the electrons and the refractive index and
dimensions of the dielectric. This work describes the continuation
of an experiment designed to verify the proposed
radiation using 100 MeV electrons and a polyethylene slab.
Problems encountered during the experiment are discussed
and suggestions for continuing work are provided. Radiation
is produced at several discrete frequencies, which are harmonics
of the electron bunch frequency as produced by the
LINAC. The absence of modes at the resonant frequency of
the dielectric is understandable, considering the short
length of the resonator. When the limitations imposed
by the physical dimensions of the dielectric slab are
considered, the results support the prediction.
