FAIR-EXPERIMENTS-14 Implementation of a Hough Tracker for CBM*

By C. Steinle, A. Kugel, R. Männer and The Cbm Collaboration


Abstract: In this report we describe an adaptation of the Hough Transform for the tracking of particles in the CBM STS detector, together with a possible implementation of the algorithm in hardware using FPGAs. Hough Transform The Hough transform is a global method for track finding. All STS detector hits have to be transformed into a parameter space according to the components of the track momentum p (θ,-q/pxz, m). This leads to our 3D Hough transform [1]. The goal of the implementation is to process the tracking with maximum speed, e.g. to process one detector hit per clock cycle. Therefore the complicated calculations of the Hough transform according to the real detector geometr
