A generator of coherent short-wave radiation, called creditron, is proposed, which uses relativistic particles moving in trochoids in crossed electric and magnetic fields, and its physical foundations are described. It is shown that the wavelength of the generated radiation depends on the particle energy as in free electron lasers, but, in contrast to the latter, these installations can employ electron beams with wider energy scatter and lower density, i.e., beams, which arc currently available. The effect of the Coulomb field and the possible methods of particle focusing in such installations are considered.
