Abstract

The advantage of using high-resolution powder diffraction data to resolve ambiguities in powder diffraction analyses is widely understood. The problem with using such an instrument for routine analyses is the length of time needed to acquire a data set. An obvious solution is to introduce some parallelism in the detector/analyzer system. The system described here uses monolithic elastic design principles to construct a simple 16-element crystal analyzer, and it uses silicon multi-detector technology developed at Brookhaven to provide a compact 16-channel pulse-counting detector system. Together these components can decrease the data collection time by at least a factor of 10. Simple replication of components could further increase the efficiency of collection.
