We present experimental results on fragmentation charge-changing cross sections of 158 A GeV lead ions (charge Z = 82e) incident on Cu and CR39 targets. To detect and identify the relativistic ions, the nuclear track detector CR39 was used. When an ion crosses a nuclear track detector foil, it produces damages at the level of molecular bonds, forming the so called “latent track”. During the che...

A description, results and the current status of the track-finding routines developed for the Transition Radiation Detector (TRD) of the CBM experiment are presented. The trackfinding algorithm is based on the Kalman Filter and track following methods. Two different approaches have been used: a standalone TRD track-finder (using only TRD information) and an algorithm based on the information fr...

The successful application of the TRD tracking algorithms [1] lead to the idea to generalize and optimize those algorithms in a flexible way in order to make them applicable for other, similar detectors. In this contribution we present how this idea was realized and applied for the TRD layout optimization and for track finding in the MuCh detector. Since both tracking detector setups (TRD and M...

The three-dimensional and analytical theory for track growth in solid state nuclear track detector is incorporated in a computer program for calculating track parameters and for plotting track-wall profiles and contours of the track opening in the LR115 detector irradiated by alpha particles. Some differences between the behavior of CR39 and LR115 detectors are discussed. Track parameters as we...
