Abstract
In previous studies, various semi-insulating LEC GaAs crystals were ir radiated with photons in the diagnostic energy range (20-100 keV), in view of a possible application in digital radiography. Solid-state and irradiation measurements, together with Monte Carlo simulations, have indicated good candidates for this application among the crystals we have investigated. In this paper we present results concerning the det ection characteristics (detection efficiency, charge-collection effici ency and energy resolution as functions of the bias voltage) of one of these materials and the images obtained by a pixel detector made on t he same material and a bump-bonded electronic system.
