PANDA is an experiment for hadron spectroscopy which will be build in Darmstadt at the future site of FAIR. Main goals of the experiment are the search for new states and the precise measurement of the line shapes of known charmonium states with the energy scan method. To normalize measured data, precise knowledge of the luminosity is vital.
At the PANDA experiment the luminosity will be measured via the angular distribution of antiproton-proton elastic scattering. The luminosity detector will consist of 4 planes of silicon-pixel-sensors (HV-MAPS) to measure the track distribution of antiprotons depending on the scattering angle. The online reconstruction of the tracks will be performed on GPUs. After the tracks are reconstructed, only the data containing tracks will be saved for further processing while the rest gets discarded.
In this talk the status of the online track reconstruction and the data acquisition of the luminosity detector will be presented.
