The studies of plasmas generated by laser-matter interaction requires detectors that are able to perform the time resolved imaging of photons and charged particles. Such information are necessary in order to characterize the time evolution of fundamental parameters (as temperature, density, etc.) of plasma. One of the key elements of such diagnostics is the position sensitive anode. We are studying a new type of position-sensitive anode which will be realized by using silicon planar technology: a trapezes and stripes resistive anode ( ...
