Protons on the move

The BASE international research collaboration, in which Heinrich Heine University Düsseldorf (HHU) is strongly involved, has successfully relocated protons outside of an antimatter laboratory for the first time with the help of an autonomous, open Penning trap. This breakthrough marks a significant step toward transporting antiprotons produced at the European Organisation for Nuclear Research (CERN) to high-precision laboratories such as BASE-HHU, which operate independently of the research facility. As the researchers now explain in the scientific journal Nature, extremely precise measurements to compare matter and antimatter are only possible far from accelerator facilities.
