Abstract
The photoresponse of a diamond detector has been compared with a standard ionization chamber in x-ray absorption spectroscopy applications. A photoconductive device based on a nitrogen-doped single crystal diamond has been tested by synchrotron radiation. Time stability and linearity have been studied by x rays at 10 keV to assess its performances. Finally, extended x-ray absorption fine structure at the Fe K-edge was carried on a standard iron target using both the diamond device and the IC. Spectroscopical results have been compared including references to literature. (C) 2008 American Institute of Physics.File in questo prodotto:
