“…The two kinds of leakage current are due to the bulk and surface properties of the material. Bulk current is primarily caused by carriers that are thermally energetic enough to cross the band gap of diamond [3]. This bulk leakage current is inversely proportional to carrier lifetime.…”

Diamond has several desirable features when used as a material for radiation detection. With the invention of synthetic growth techniques, it has become feasible to look at developing diamond radiation detectors with reasonable surface areas. Polycrystalline diamond has been grown using a chemical vapour deposition (CVD) technique by the University of Augsburg and detector structures fabricated at the James Watt Nanofabrication Centre (JWNC) in the University of Glasgow in order to produce pixelated detector arrays. The anode and cathode contacts are realised by depositing gold to produce ohmic contacts. Measurements of I-V characteristics were performed to study the material uniformity. The bias voltage is stepped from -1000 V to 1000V to investigate the variation of leakage current from pixel to pixel. Bulk leakage current is measured to be less than 1nA.

CVD diamond detectors are of interest for charged particle detection and tracking due to their high radiation tolerance. In this article we present, for the first time, beam test results from recently manufactured CVD diamond strip detectors and their behavior under low doses of electrons from a β-source and the performance before and after intense (> 10 15 /cm 2 ) proton-and pion-irradiations. We find that low dose irradiations increase the signal-to-noise ratio (pumping of the signal) and slightly deteriorate the spatial resolution. Intense irradiations with protons (2.2 × 10 15 p/cm 2 ) lowers the signal-to-noise ratio slightly. Intense irradiation with pions (2.9 × 10 15 π/cm 2 ) lowers the signal-to-noise ratio more. The spatial resolution of the diamond sensors improves after irradiations.corresponding author: Dirk.Meier@cern.ch Submitted to Elsevier
