ABSTRACT
The ion beam of very low current (100-1000 ions/second) focussed to a micron or submicron spot is used as a probe for testing the transport properties of charge created along the path of particular ion in the sample. This technique named IBIC (Ion Beam Induced Charge), has been used in research of charge transport properties in CVD diamonds. Results of IBIC measurements with 2 MeV protons and alpha particles are images of the material microcrystaline "electric" structure. Since protons and alpha particles have different ranges, charge collection efficiency images for different average sampling depths were obtained.
