Single Crystal Goniometer for X-Ray and Neutron Diffraction

Abstract

A single crystal goniometer intended both for x‐ray and neutron diffraction analysis has been used in neutron diffraction work at the Kjeller reactor. The unique feature of this goniometer is a macromodel of the unit cell designed for easy orienting of the crystal. A special arrangement is provided for setting any plane in reflecting position without previously calculating the angles, and a set of three‐dimensional data can be recorded on a counter moving in the horizontal plane.
