Scientists have successfully transported antiprotons by road for the first time, using a specially designed trap on a truck. The BASE collaboration reported that they stored antiprotons in this mobile trap for over a month, marking a significant breakthrough.
The study aims to compare protons (positively charged particles) and antiprotons (their antimatter counterparts) to explore potential differences in mass or magnetic moments, which could shed light on the universe’s matter-antimatter asymmetry.
Utilizing ultra-high vacuum Penning traps, the BASE (Baryon Antibaryon Symmetry Experiment) operates at CERN’s Antimatter Factory, the sole global facility for producing, storing, and studying low-energy antiprotons.
The research team successfully transported 92 antiprotons along a 7.5 km route without loss or degradation of the trap vacuum, paving the way for more precise measurements away from CERN, where magnetic fluctuations hinder accuracy.
Future plans involve moving these antiprotons to a high-precision laboratory at Heinrich Heine University (HHU) for comparison studies and to enhance measurement precision significantly. After a successful test run in March, the team aims to ensure the transport system can operate autonomously for ten-hour trips from Geneva to Düsseldorf.
