High-resolution tracking with silicon strip detectors for relativistic ions

Tracking with silicon strip detectors for relativistic ions has been investigated using a ¹²C beam of 1.5 GeV/ u at GSI. The ionization charge spectrum and the charge sharing between strips are presented. The strip cluster of carbon ion can be selected based on the cluster charge with high efficiency and little contamination. The spatial resolution of the silicon strip detectors is evaluated. The angular distribution of multiple Coulomb scattering was investigated with lead absorbers. The results are compared to the Molière theory and the Gaussian approximation of GEANT calculations.
