The PANDA experiment (antiProton ANnihilation at DArmstadt) is one of the four key experiments to be operated at FAIR (Facility for Antiproton and Ion Research), which is currently under construction near Darmstadt/Germany. This fixed target experiment will address a wide range of open questions in the field of hadron physics. The detector consists of at target as well as a forward spectrometer to fully exploit the forward boosted collisions of antiprotons with dense hydrogen or nuclear targets. Phase-space cooled antiprotons with momenta in the range of 1.5 GeV/c to 15 GeV/c provided by the High Energy Storage Ring (HESR) allow for high precision line-shape scans. The ability to perform exclusive reconstruction of arbitrary final states enables a physics program including topics such as spectroscopy in the charmonium and open-charm region, proton structure, and hyperon and hypernuclear physics. The talk will give an overview of the PANDA experiment and highlight the most important aspects of the physics program.

PANDA Annual Report 2019

The PANDA Experiment, which is located at the High Energy Storage Ring at the FAIR accelerator center in Darmstadt, Germany, is optimized for questions of hadron physics. With this detector it will be possible to discover new states and measure their line shapes as well as the line shapes of already known states very precisely. To normalize the energy scan measurements exact knowledge of the luminosity is required. The luminosity at PANDA will be determined from the angular distribution of elastical antiprotonm proton scattering. In order to achieve an absolute measuring accuracy of 5% , the tracks of the scattered antiprotons will be measured by four planes of thinned silicon detectors (HV-MAPS). HV-MAPS are pixel sensors with integrated readout electronics. They will be operated with a reverse voltage of 60 volts to increase their radiation hardness. The four detector planes consist of CVD-diamonds on which the sensors are clued. To reduce the multiple scattering the detector is operated in a vacuum. The concept of the luminosity detector is presented and technical aspects such as the vacuum system, cooling, electronics, and sensors are discussed, as well as insights into data analysis.
