A TECHNIQUE FOR THE GROWTH OF HIGH QUALITY SINGLE CRYSTALS OF ICE

M. Ohtomo , S. Ahmad , R. Whitworth

A new technique is described for the growth of single crystals of ice of low dislocation density. No seed crystal is required and the water is frozen from the bottom upwards so that it is possible to work with a vacuum or controlled atmosphere above it. Crystals of 45 mm diameter and 80 mm long have been grown and found by synchrotron radiation topography to have dislocation densities less than about 100 cm-2.
