Comparison of channeling radiation from diamonds with and without platelets

Abstract

Channeling-radiation spectra produced by planar-channeled relativistic positrons and electrons in Type-Ia and Type-IIa diamonds have been measured. Because of the presence of platelets in the Type-Ia diamond, some of the spectra measured for this crystal differ markedly from their counterparts for the Type-IIa diamond. These striking differences illustrate the potential applications of channeling radiation as a diagnostic tool for studies of impurities or defects in crystals.
