TY - JOUR AU - Forrester, J D AB - A liquefier cryostat is used to produce the liquid hydrogen and the crystal is cooled in situ to liquid-hydrogen temperature. This method introduces problems involving crystal cooling, crystal mounting, the rotation of the crystal and the provision of X-ray transparent windows in the cryostat walls. These are discussed, together with some preliminary results obtained with the apparatus.
