Research Objective

Large-area silicon detector systems for tracking and vertex detection are of central importance to frontier precision hadron physics experiments. Examples are the CBM and the PANDA projects planned at the international research facility FAIR. Their physics with rare probes (e.g. open charm) demands for unprecedented silicon detector performances. One of the key requirements is an ultra-light-weight construction of the detector systems as a whole, essential for high-resolution determination of the particles momenta and the vertex identification of short-lived decays. This is particularly challenging because in the new experiments high particle multiplicities (up to 1000 per event) and high nuclear interaction rates (up to 10 million per second) require a large number of fine-pitch detector channels equipped with fast and thus power dissipating front-end electronics. The necessary cooling infrastructure would introduce an excessive material budget in the tracking system aperture, making the required high-resolution momentum and vertex measurements impossible if the detector systems were built similar to current state-of-the-art designs realized e.g. in tracking detectors of LHC experiments at CERN. In this research activity we propose to explore new innovative technologies and system concepts to demonstrate that high-performance, ultra-low-mass detector systems for tracking and vertex detection can be built compatible with the large-area requirement. This will be addressed in three R&D projects each focusing on a different system challenge.
