This was the situation in the Crystallography Section, for single crystal work was performed with Weissenberg and Buerger-type precession cameras. The precession camera was chosen for our investigation because, unlike the Weissenberg instrument, it had space available to accommodate the pressure cell and its design was simple to modify.
The pressure cell, mounted on a crudely modified Buerger-type precession camera, is shown in Fig.
Also, a new precession camera with a massive goniometer head was built to support the weight of the Be cell and to permit large translational and angular ranges for centering and orienting the crystal (10).
The loaded cell was mounted on the precession camera at RT and as many reciprocal lattice planes as possible were recorded on film.
