A universal high-temperature device for single-crystal diffraction

Abstract

The construction of a heating device for single-crystal diffraction is presented. The device operates with two coaxial gas streams, the central one of which is electrically heated by means of a resistance wire. As a result the crystal temperature is not affected by external factors such as flowing air etc. Temperatures up to 1000 K can be reached and maintained to within 1 K for extended periods. The device fits on a standard goniometer head and can, without any special options, be installed on any single-crystal diffractometer or camera.
