A read-out system for the PANDA MVD prototypes: development and results. — •Alessandra Lai, Tobias Stockmanns, and James Ritman for the PANDA collaboration — Forschungszentrum Jülich, Germany

The PANDA experiment will play a key role at the upcoming Facility for Antiproton and Ion Research (FAIR) in Darmstadt. Exploiting proton-antiproton interactions, its scientific program addresses fundamental questions of QCD. The Micro Vertex Detector (MVD) is the sub-detector system closest to the interaction point. It uses two different kinds of silicon detectors as sensitive elements: hybrid pixel detectors and double-sided strip detectors. Two different types of front-end ASICs are under development for the MVD: the Torino Pixel ASIC (ToPix) and the PANDA Strip ASIC (PASTA). Both are designed to transmit untriggered data at a rate of hundreds of Mb/s and handle the expected hit rate in hot spots of the detector. A test system capable of handling these high rates is therefore needed. It should have the flexibility to test different kinds of front-end electronics and be easy to adapt to new prototypes. Therefore, an FPGA-based system is the ideal candidate. Suitable firmware and a software framework are thus under development at the Forschungszentrum Jülich.

In this talk, the mentioned read-out system will be introduced and performance tests with the front-end electronics prototypes of the MVD will be presented.
