Date/Time: Thu Aug 13 2026 at 14:00<br/><br/>Location: Auditorium<br/><br/>Speaker: Thomas Rudzki (Paul Scherrer Institute)<br/><br/>Title: From Fundamental Physics to Applications: Monolithic Pixel Sensors at PSI<br/><br/>Abstract: The High Intensity Muon Beam (HIMB) at PSI will open new opportunities for precision and high-rate measurements in both particle physics and material science. A central technology driving this progress are High-Voltage Monolithic Active Pixel Sensors (HV-MAPS), which combine fast, granular detection with an ultra-low material budget ? a crucial requirement for experiments with low-momentum particles. At PSI, these sensors form the core of the Mu3e experiment, where innovative approaches to assembly, qualification, and gaseous helium cooling have enabled the construction of the world?s lightest pixel tracker to date. This effort culminated in the successful installation of the complete Mu3e vertex detector in 2026. The experiment is now preparing for a commissioning and calibration run in autumn, aimed at validating detector performance, data acquisition, and real-time data filtering under operational conditions. In parallel, the technology has been transferred to muon spin rotation (µSR), making vertex reconstruction possible and thereby allowing measurements at much higher counting rates with high lateral resolution spectroscopy in material science. By outlining these developments, the talk will show how pushing pixel technology to its limits creates synergies between fundamental discoveries and applied innovation at PSI.
