Abstract

The feasibility of diamond position sensitive detectors for deep UV light monitoring is reported. Based on voltage-division principle, a very simple one-dimensional photosensitive structures have been developed exploiting the strong variation of polycrystalline diamond conductivity under UV-light irradiation and dark conditions. Lumped and finite elements analysis have been used to compare the theoretical expectations with the experimental results obtained under excimer laser illumination. A complete characterization of such a 1D position sensitive device has been performed in terms of: the beam intensity insensitivity (over three orders of magnitude); the output signal dependence on the beam width; and the contact structure and its resistance influence on the device performances.
