ABSTRACTThe minimum-detectable-limit of a compact double-focusing graphite mosaic-crystal spectrometer is compared to the minimum-detectable-limit from a high-performance Ge solidstate detector. The solid angle and efficiency of the solid-state detector is much greater than for the crystal spectrometer. However, the better signal-to-noise of the spectrometer and its insensitivity to matrix fluorescence and scattering can give it a better minimum-detectable-limit for trace element analysis. The relative advantages of the two detectors are illustrated for some simple test samples. The performance of the crystal spectrometer compared to the solid-state detector increases as the flux in the x-ray probe increases. This makes crystal spectrometers especially interesting for use with new high intensity 3rd generation synchrotron microprobes. An estimate is made of the source and sample conditions favored for each detector.

The silicium solid-state detector has been used as control-detector in the X-ray photometer system on board of the satellite Interkosmos 1.The effectiveness of the use of such detector as control-unit for radiation-belts has been confirmed also as independent indicator of high energy X-ray quants during high levels emission of solar active regions.

AbstractWe have utilized white x-ray beam and a Ge solid state detector, in energy dispersive mode, to study the diffraction from the surface layers of ceria deposited on (001) surface of Y stabilized cubic zirconia with grazing incident beam. We found that ceria forms islands, oriented epitaxially with respect to the zirconia substrate, with a lateral coherence of the order of 60 Å.
