Implementation of Pattern Recognition for the PANDA Forward Tracking System* — •Martin J. Galuska, Jifeng Hu, Wolfgang Kühn, J. Sören Lange, Yutie Liang, David Münchow, Björn Spruck, and Milan Wagner for the PANDA collaboration — II. Physik. Inst., JLU Gießen
The planned PANDA fixed-target experiment will operate with up to 2·107 antiproton-proton or antiproton-nucleus collisions per second. Up to 8 primary charged particles per event are expected to reach the acceptance of the PANDA Forward Tracking System (FTS) detector which is comprised of 6 stations with 4 straw tube double layers with drift times ≤150 ns. With ≥99.6% probability the signals of ≤8 events will have to be processed simultaneously at the peak interaction rate of 20 MHz.
A Hough transform based charged particle tracking algorithm for the PANDA FTS detector was developed. In the region of the PANDA Forward Spectrometer it uses a 3-stages track model of line+parabola+line for the projection of the track into the bending x-z-plane. The projection into the non-bending y-z-plane is approximated by a straight line. Results on efficiency and momentum resolution will be presented.
