Abstract

The development of a pressure cell using Merrill-Bassett geometry is described, that avoids the use of beryllium. Nevertheless, an opening angle of 90° was obtained for the X-rays using a new mounting technique for the diamonds. The cell was specifically designed for comfortable use on modern single-crystal diffractometers with area detectors. It has the additional advantage that no absorption correction is necessary for the cell. It is intended for pressures up to 10 GPa, the range in which liquid pressure-transmitting media are available.

The first results are presented, including comparative investigations with a single-counter diffractometer equipped with an edge-collimator.
