Stimulated shortwave radiation from charged particles in naturally occurring hollow channels
Abstract
The design of systems for producing stimulated coherent X- and gamma-ray emission using a beam of relativistic charged particles moving in hollow cylindrical channels is considered. Zeolyte crystals or chrysotile-asbestos fibers may be used as the working medium containing the hollow channels. When relativistic charged particles are channeled, efficient, selective population of isolated axial kinetic energy levels occurs and is accompanied by complete inversion of the working transition. Optimal parameters for minimizing the gain threshold are calculated. A current density of approximately 10 to the 6th-10 to the 8th A/sq cm is required to achieve a gain of 1-10/cm for wavelengths of approximately 1-10 A when relativistic positron beams of energy E of approximately 50 MeV are employed.
