CERN Group Traps Antihydrogen

Trapping antihydrogen atoms at the European Organization for Nuclear Research (CERN) has become so routine that physicists are confident that they can soon begin experiments on this rare antimatter equivalent of the hydrogen atom, according to researchers at the University of California, Berkeley. “We’ve trapped antihydrogen atoms for as long as 1,000 seconds, which is forever” in the world of high-energy particle physics, said Joel Fajans, UC Berkeley professor of physics, faculty scientist at Lawrence Berkeley National Laboratory and a member of the ALPHA (Antihydrogen Laser PHysics Apparatus) experiment at CERN in Geneva, Switzerland.
