Earlier this week, a team of scientists from the BASE experiment #AtCERN succeeded in transporting antiprotons in a truck across the Laboratory’s main site.
Christian Smorra explains how the BASE-STEP portable antiproton trap captures and stores antiprotons.

#ThrowbackThursday to September 1979, when CERN celebrated its 25th anniversary 🎉
During the first 25 years (1954–1979), several groundbreaking accelerators were built #AtCERN which allowed to make discoveries that later helped establish the modern #StandardModel of particle physics.
