Abstract

The realization and characterization of a compact 64-pixel detector based on CVD-dia- mond is here presented and discussed. Each pixel has been connected to a dedicated multichannel read-out electronics designed for acquisition, conditioning and elaboration of the pixel-signal, al- lowing a real-time beam profile reconstruction of the impinging radiation. The back-side semi- transparent contact was used for diamond sensor biasing. Detector characterization was per- formed under a weak continuous UV light spot obtained at the output of a monochromator illumi- nated by a deuterium lamp. Sensor was also characterized by X-ray illumination evaluating both displacement and broadening of impinging spot. Finally, photodetector response was observed un- der pulsed UV laser light, demonstrating the feasibility of a real-time beam monitoring for such a kind of light source.
