Characterization of CVD-diamonds for radiation detection

We report the results of our investigations on high quality single crystal chemical vapor deposition (SC-CVD) diamonds to be used as ionizing radiation detectors. Recent progress in growth of synthetic diamonds of very high purity and high homogeneity has opened perspectives to a new type of UV photosensors in order to work with large volume two-phase liquid-Ar and/or liquid-Xe detectors, nowadays under design for next generation dark matter search. SC-CVD diamonds supplied by Brevetti Bizz firm of San Bonifacio (VR, Italy) were investigated and the results are presented and discussed.
