A new cooling technique means that the ALPHA experiment at CERN’s Antimatter Factory can produce antihydrogen atoms eight times faster than before In a paper published today in Nature Communications, researchers at the ALPHA experiment at CERN’s Antimatter Factory report a new technique that allows them to produce over 15 000 antihydrogen atoms – the simplest form of atomic antimatter – in a matter of hours. “These numbers would have been considered science fiction 10 years ago,” said Jeffrey Ha...
