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
