Silicon pixel sensors for the PANDA luminosity detector — •Niels Boelger, Stephan Bökelmann, Florian Feldbauer, René Hagdorn, Stephan Maldaner, Gerhard Reicherz, and Miriam Fritsch — On behalf of the PANDA Collaboration — Ruhr University Bochum AG Physics of Hadrons and Nuclei, 44780 Bochum

The PANDA experiment is one of the key experiments at the future FAIR accelerator facility in Darmstadt. Its purpose is to study the properties of hadronic states in detail and to search for exotic states of matter.
The PANDA detector will have a luminosity detector 11 meters downstream from the interaction point. This detector, consisting of two retractable half-detectors, uses silicon pixel sensors to measure the distribution of elastically scattered antiprotons as a function of the scattering angle, from which the luminosity is determined. The MuPix sensors intended for track reconstruction in the luminosity detector are High-Voltage Monolithic Active Pixel-Sensor (HV-MAPS), which offer two advantages over conventional pixel sensors: The active sensor part and the readout electronics are combined on the same chip. Secondly, due to the high voltage, the charge transport is much faster. The production of sensor modules consisting of several pixel sensors, as well as the data acquisition system prepared for this setup will be presented.
