Abstract: The PANDA (AntiProton Annihilations at Darmstadt) experiment at FAIR facility investigates antiproton-proton annihilations and the nature of the strong interaction. The central Straw Tube Tracker (STT) at PANDA consists of over 4600 single straw tubes, each with a length of 140 cm and a diameter of 1 cm. The expected particle rate is up to about 1 MHz per straw tube which could lead to a data rate up to 20 GByte/s. Our group at Forschungszentrum Juelich exploits the large experience with straw tubes, the DAQ system and signal processing at WASA at COSY, COSY-TOF detector. Using the actual ADC based hardware for pulse analysis and test of new signal processing algorithms, we develop a new DAQ architecture for PANDA STT that fulfills requirements for time and energy resolution, providing at the same time additional processing features: event building, filtering and track reconstruction. This system involves more data for processing than that one currently used at COSY, and gives new possibilities to reject irrelevant events. To build such a system an appropriate platform with a high hardware integration level and full mesh interconnection is needed.
