For the first time in history, antimatter was transported by truck.
For the first time in stories A successful transport of antimatter was completed using a truck specially equipped for this purpose. Yesterday, as part of the Baryon-Antibaryon Symmetry Experiment (BASE) at the European Organization for Nuclear Research (CERN), the BASE-STEP antiproton trap was successfully moved across the entire main laboratory complex.
A statement from CERN's press service reported that scientists managed to collect a cloud of 92 antiprotons in an innovative portable cryogenic Penning trap, then detach it from the experimental setup, load it into a van, and, after transporting and unloading the antimatter, continue experiments with it. The experiment is not only complex but also dangerous, given that antimatter is extremely difficult to contain, as it annihilates upon contact with "ordinary" matter, causing a powerful explosion. However, the explosion is less terrifying than the loss of the precious samples that scientists have spent years literally collecting atom by atom.
The BASE-STEP system is a device weighing approximately 1 ton, equipped with a superconducting magnet, cryogenic cooling with liquid helium, a backup power supply, and a vacuum chamber. The device can withstand shock and vibration during transport. The trap uses magnetic and electric fields to contain the antiparticles. A fairly ordinary truck (pictured) was used to transport the complex equipment containing the antimatter.
The goal of the experiment is not simply a demonstration, but a practical one. A successful experiment will enable the safe transport of antiprotons to other European laboratories, such as the Heinrich-Heine-University of Düsseldorf (HHU), where high-precision measurements of the properties of antimatter can be performed.
CERN researcher Stefan Ulmer explained the practical purpose of the experiment:
Machines and equipment at CERN's "antimatter factory," where the BASE facility is located, create magnetic field fluctuations that limit the accuracy of our measurements. To better understand the fundamental properties of antiprotons, the experiment will need to be moved outside the laboratory building. In the long term, we want to be able to transport antimatter to any laboratory in Europe.
The CERN Antimatter Laboratory is the only place in the world where antiprotons can be produced, stored, and studied. Previous experiments have developed an innovative approach that allows for the next step: transporting antiprotons to a self-contained environment for more precise research and for sharing them with other scientists.
CERN Director of Research and Computing Gautier Hamel de Moncheneau:
Antimatter transport is a groundbreaking and ambitious project, and I congratulate the BASE collaboration on this impressive achievement. We are at the beginning of an exciting scientific avenue that will allow us to explore antimatter even more deeply.
Last May, the BASE-STEP container and transport system were already tested at the center's site. However, they didn't risk immediately launching the system with antimatter, instead testing it with 100 "regular" protons. CERN physicists now face a second, much more complex stage of the experiment, during which the container with antimatter will be transported by truck to Düsseldorf. The delivery will take over eight hours.
