Breakthrough cooling technique boosts antihydrogen production to record levels

SMRTR summary

CERN scientists achieved a breakthrough in antimatter production by developing a new cooling technique that generates over 15,000 antihydrogen atoms in just hours compared to previous methods requiring 10 weeks. The technique uses laser-cooled beryllium ions to cool positrons to -266°C, boosting production rates eightfold and enabling unprecedented antimatter research.
