FPGA helix tracking algorithm for PANDA — •Yutie Liang, Martin Johannes Galuska, Jifeng Hu, Wolfgang Kühn, Jens Sören Lange, David Münchow, Björn Spruck, and Hao Xu — II. Physikalisches Institut, Giessen University, 35392, Germany

The PANDA detector is a state-of-the-art general-purpose detector for physics with high luminosity cooled antiproton beams, planed to operate at the FAIR facility in Darmstadt, Germany. Without any hardware trigger, large amount of raw data are streaming in the data acquisition system. The data reduction task is performed in the online system by reconstruction algorithms programmed in VHDL (Very High Speed Integrated Circuit Hardware Description Language) on FPGAs (Field Programmable Gate Arrays). One important part in the system is the online track reconstruction. In this presentation, an online tracking finding algorithm for helix track reconstruction in the solenoidal field using conformal transformation and Hough transformation is shown. The MVD (Micro Vertex Detector) and STT (Straw Tube Tracker) are used in this algorithm.
