摘要：

We have evaluated 2 small-pixel (0,65 mm) Cadmium-Zinc-Telluride arrays with thickness of 1 and 2 mm that were fabricated for MSFC by Metorex and Baltic Science Institute (Riga, Latvia). Each array was optimised for temperature and collection bias and was then exposed to Cadmium(109), Am-241 and Fe-55 laboratory isotopes to measure the energy resolution for each pixel. The arrays were then scanned with a finely-collimated X-ray beam, of width 100 micron, to examine pixel to pixel. and inter-pixel charge collection efficiency. Preliminary results from the array tests are presented.
