Abstract
The stability of the high pressure ice forms discovered by Tammann and Bridgman at very low temperatures and atmospheric pressure has made it possible to obtain x‐ray diffraction photographs of these forms. A discussion is given of a low temperature powder camera designed (1) to permit continuous rotation of the crystal, (2) to permit very rapid insertion and centering of the crystal, (3) to permit evacuation of the diffraction chamber. A detailed description of the experimental technique is made including the operation of the camera, and a method for powdering the ices by grinding and repacking them while under liquid air. Two diffraction patterns of the high pressure ices are shown.Keywords
