21st International Conference on Positron Annihilation

We are very pleased to announce that we will be hosting the next positron conference “The 21st International Conference on Positron Annihilation” in Garching from September 10th to 15th 2028. The local organizing committee is chaired by Christoph Hugenschmidt, head of the TUM research group Physics with Positrons at the MLZ.

The ICPA series was initiated in 1965 dedicated to the study and application of positron and positronium annihilation. This triennial event attracts top researchers from physics, materials science, chemistry, and biomedical engineering to present cutting-edge developments in positron research.

ICPA-21 will showcase the latest breakthroughs in positron science, spanning from fundamental research to applied material diagnostics. This global gathering brings together a vibrant community of young researchers and established experts working at the exciting interface between antimatter and matter. Key topics include advanced positron annihilation spectroscopy, defect characterization in solids, positronium chemistry, positron beam techniques, and innovative applications in semiconductors, porous systems, and biological imaging. With special focus on emerging frontiers—like AI-assisted data analysis and antimatter studies at facilities such as CERN—ICPA-21 offers a platform for bold ideas and cross-disciplinary collaboration. By bridging theory, experiment, and application, ICPA-21 promises to be a catalyst for scientific discovery and technological innovation.
