Abstract

In many fields of cryogenic work the design of the equipment depends solely on the low temperature requirements and in many cases where actual physical measurements are required, the method of measurement can readily be adapted to the low temperature design. However, this is not the case in measuring lattice parameters by the Debye-Scherrer powder method as the X-ray optical requirements of the instrument must remain, in essence, the same as those of conventional room temperature cameras. In general it is best to consider the problem as one of adapting a conventional room temperature design to take in low temperatures as well. The basic problem is therefore one of locating and rotating a specimen, of accurately controlled and measured temperature, in a collimated X-ray beam with provision for recording the diffracted X-ray beams over nearly the whole angular field of diffraction.
