CERN's BASE team transports trapped antiprotons by truck for first time

Researchers from the BASE Collaboration at CERN sealed 92 antiprotons inside a specialized ultrahigh-vacuum trap, then drove them 7.5 kilometers around the lab's grounds without losing them. The experiment, published in Nature, demonstrates that antimatter can survive real-world transport rather than staying confined to the site where it's produced.

BASE-STEP demonstrates transportable trap for holding antiprotons

CERN's BASE-STEP experiment built a compact catching trap using 15 stacked electrodes and magnetic confinement to capture antiprotons from a degraded beam, cool them with cotrapped electrons, and clean out contaminant particles like electrons and negative ions through voltage ramping and dipolar drives. The particles are then moved into a compensated Penning trap at the center of the device for stable, non-destructive detection and storage.
