A parametrisation of the energy loss distributions of charged particles and its applications for silicon detectors

The energy loss distribution of charged particles in silicon is approximated by a simple analytical parametrization. Its use is demonstrated through several examples. With the help of energy deposits in sensing elements of the detector, the position of track segments and the corresponding deposited energy are estimated with improved accuracy and less bias. The parametrization is successfully used to estimate the energy loss rate of charged particles, and it is applied to detector gain calibration tasks.
