N2 - A method of determination of charge and energy for energetic particles penetrating (not stopping) a multilayer silicon ΔE × E telescope with a finite thickness (12 mm) is examined in the energy region up to several hundreds of MeV/nucleon. From the results of the accelerator experiment, an energy resolution σE of 1.2% in rms and a charge resolution σZ of 0.11 charge unit in rms for Fe-group nuclei with energies between 190 and 230 MeV/ nucleon are obtained. For lighter elements such as hydrogens and helium ions, an energy resolution σE of 2.9% is obtained in the energy region between 33 and 42 MeV/nucleon and even their individual isotopes are separated. Also, the energy dependences of these resolutions suggest that this method can be utilized for particles with energies about two times larger than that corresponding to the range of telescope thickness for the evaluation of the space radiation effects even under the limitations of weight, size, and electric power supply.
