 note = {application/pdf, 紀要論文, In 2007, ACCESS (Advanced Cosmic ray Composition Experiment for the Space Station) on the International Space Station (ISS) detectors will measure the individual elemental composition of cosmic rays at energies a thousand times higher than any previous measurement of similar resolution-reaching to 10^<15> eV for understanding of the origin, source and acceleration mechanism of cosmic rays. We can determine the charge of cosmic rays using the silicon detector, one of the detectors in ACCESS. We simulate the reaction of very high energy heavy ions in silicon detector by Geant4 simulation tool. The simulation is carried out for one layer Si-detector and full ACCESS structure. The heavy ions (Z up to 28) with high energies from 10 GeV to 10 TeV penetrate one silicon layer with various thickness and the ions from 1 to 100 TeV penetrate the full detector. The results show that energy loss is linearly proportional to Z^2 and thickness. In full ACCESS simulation we can distinguish the backscattered particles originated in calorimeter from primaries. In order to determine the contamination of the backscattered particles in\
the primaries in each pixel, the average distance distribution of the primary particles and the backscattered particles are calculated. Results show that the secondary particles do not affect so much for the identification of each element.},
