Radiation monitoring with CVD diamonds in BaBar

The BaBar experiment has been using two polycrystalline chemical-vapor-deposition (pCVD) diamonds for radiation monitoring for nearly two years. In July 2005, an additional twelve diamond based radiation sensors will be installed inside the BaBar detector. These diamonds will take over the function of twelve silicon PIN-diodes that are currently used in the radiation protection and monitoring system. We describe our experience with using pCVD diamond radiation sensors in a high energy physics experiment. We also detail some of our findings from our research and development of pCVD diamond based radiation sensors.
