Two different GaAs crystals, one LEC and one LPE, have been irradiated with photons of various energies, to compare their response in view of a possible application for digital radiography. Experimental results include I-V curves, charge collection efficiency, detection efficiency and energy resolution as a function of bias. A comparison is made with a simulation program that takes into account X-ray interactions, electric field and charge trapping inside the material
