Preliminary results from small-pixel CdZnTe arrays

We have evaluated 2 small-pixel Cadmium-Zinc-Telluride arrays with thickness of 1 and 2 mm that were fabricated for MSFC by Metorex and Baltic Science Institute. Each array was optimized for temperature and collection bias and was then exposed to Cadmium109, Am241 and Fe55 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 test are presented.
