    The presence of impurities in natural diamond detectors and their influence on the detection properties have been investigated. A micrometer size X-ray beam generated by a synchrotron light source as well as collimated alpha particles were used to probe the effects induced by non isotropic distributions of defects on diamond detector characteristics. A strong correlation clearly appears between the measured photocurrent maps and the X-ray induced luminescence pictures. Spatially resolved alpha measurements are compared to local infrared and ultraviolet absorption measurements and demonstrate the influence of defects on local and global diamond detection spectra.
