FPGA helix tracking algorithm for PANDA — •yutie liang1, martin galuska1, thomas gessler1, wolfgang kühn1, jens sören lange1, david münchow1, björn spruck1, and hua ye2 for the PANDA collaboration — 1II.Physikalisches Institut, Giessen University, 35392, Germany — 2Institute of High Energy Physics, Beijing, China
The PANDA detector is a general-purpose detector for physics with high luminosity cooled antiproton beams, planed to operate at the FAIR facility in Darmstadt, Germany. The central detector includes a silicon Micro Vertex Detector (MVD) and a Straw Tube Tracker (STT). Without any hardware trigger, large amounts of raw data are streaming into the data acquisition system. The data reduction task is performed in the online system by reconstruction algorithms programmed on FPGAs (Field Programmable Gate Arrays) as first level and on a farm of GPUs or PCs as a second level. One important part in the system is the online track reconstruction. In this presentation, an online tracking algorithm for helix tracking reconstruction in the solenoidal field is shown. The tracking algorithm is composed by two parts, a road finding module followed by an iterative helix parameter calculation module. A performance study using C++ and the status of the VHDL implementation will be presented.
