Home to the world's only antimatter factory

Every antiproton ever studied has been measured in the same building where it was made: CERN's antimatter factory outside Geneva, the only facility on Earth that can produce and store them. On March 24, 2026, physicists loaded 92 antiprotons into a one-tonne portable trap, craned it onto a truck, and drove 10 kilometres, with roughly 91 surviving—the first time antimatter was transported beyond its birthplace.
