Future High-Energy Physics experiments pose stringent requirements on the performance of their detector systems. Silicon pixel detectors are a widely used and promising technology capable of meeting the specific needs of detectors measuring particle trajectories. In particular they allow for combining a high spatial resolution with precise timing capabilities as well as a low material budget and a high radiation tolerance. 

A large variety of silicon pixel detector technologies is explored and developed to address the specific needs of these diverse use-cases. Complementing laboratory-based measurements, pixel sensors are characterised with the help of minimum ionising particles (MIPs) at test-beam facilities such as the CERN SPS or the DESY-II test-beam facility.

This seminar gives an introduction into the R&D cycle of silicon pixel sensors with a particular focus on the basic concepts of test-beam analysis. A widely used analysis and reconstruction tool (Corryvreckan) is presented alongside with example results from performance evaluation studies of the ATLASpix_Simple high-voltage monolithic active pixel sensor prototype.
