CERN takes antiprotons for a spin in a test never tried before
- CERN in Geneva transported 92 antiprotons by road in a first-of-its-kind test on Tuesday.
- CERN suspended the antiprotons in a vacuum inside a specially designed cryogenic “transportable antiproton trap.”
- CERN held the antiprotons in place with superconducting magnets cooled to -269 degrees Celsius (-452 Fahrenheit).
- CERN drove the truck for about a half-hour on its campus to test whether the antiprotons could be transported without seeping out.
- CERN’s researchers said the trap is designed to contain the antiprotons through events like stops, starts, and braking, but can contain them for about four hours—shorter than the trip time to Düsseldorf.
