Relativistic electron beam research at M.I.T. focuses on the generation of intense coherent electromagnetic radiation in the centimeter, millimeter and submillimeter wavelength ranges. The primary radiation mechanism which is being studied at the present time is the free electron laser instability which is excited when an electron beam passes through a spatially periodic, transverse magnetic field (wiggler field). This instability is characterized by axial electron bunching and has emission wavelengths associated with the Doppler upshifted wiggler periodicity.
