Simulation of realistic detector response in the CBM Silicon Tracking System

The Silicon Tracking System of the CBM Experiment consists of eight tracking layers of silicon detectors. Each layer is an array of vertical modules containing 300 μm thick double-sided silicon strip sensors. The strip pitch is 60 μm on both sides. The sensors are segmented into 1024 strips per side. On either side the strips are tilted by +7.5◦ or -7.5◦ with respect to the vertical edge, creating 15◦ stereo angle between the opposite sides. This allows reconstructing multiple hits from the same sensor at the expense of a poorer spatial resolution in the vertical direction, keeping high resolution in horizontal direction for better reconstruction of the particle momenta.
