Abstract
A description is being developed of the spontaneous emission in a uniform magnetic field with a dielectric medium. Considered here are beam energies of up to 10 MeV, indices of refraction (n) of up to 2, and magnetic fields of up to 5 T. As long as n is a slowly varying function of the radiation frequency, the spontaneous emission may go into a large number of harmonics. Compared to a vacuum, a dielectric medium increases the overall energy emission in the 10- to 106-GHz spectral region. In this description, a new effect--a helical Cerenkov effect--is deduced whose power spectrum, unlike the usual Cerenkov effect, depends on the radius of curvature of the electron trajectory which is measured in the plane perpendicular to the direction of the electron guiding center.
