Abstract
Transition radiation is a photon production phenomena being studied at the Saskatchewan Accelerator Laboratory (SAL). When relativistic charged particles encounter sudden changes in the dielectric constant of the material through which they are passing, transition radiation occurs. The produced photons are confined to a very forward peaked cone, but with no radiation present in the straight forward direction. The angular dependence of the radiation pattern is dependent upon the structure of the incident particle beam, and thus is applicable to the field of beam diagnostics. A method for using transition radiation to measure the emittance of the electron beam has been evaluated for possible future, permanent use at the SAL facility. A periodic radiator was designed for
the generation of coherent X-ray radiation. By measuring nearly the entire radiation pattern produced from this radiator at two different target-to-detector separations, determination of the beam emittance is possible.
