TUM Research Group Physics with Positrons

We are at the forefront of world-leading research in positron physics and its transformative applications across science and technology.

Our pioneering work spans surface science, solid-state physics, and materials science, driving innovation through the development of advanced positron-based techniques and state-of-the-art instrumentation. We explore the unique capabilities of positron beams and sources to unlock new insights across a wide range of materials — from semiconductors and superconductors to metals and polymers.

Our research not only advances applied materials science but also delves into the fundamentals of leptonic systems and antihydrogen, contributing to our deeper understanding of the universe.

Highlights:

• Worlds most intense positron beam
• The only scanning positron µ-beam in operation worldwide
• First time-resolved positron Auger spectroscopy
• High-precision measurement of the Ps⁻ decay rate
• First spin-resolved measurement of Fermi sheets in Heusler alloys
• Towards the first pair-plasma on earth
• First spatial resolved Tc measurement in High-Tc superconducting films
