Antimatter atoms trapped for 1000 seconds

The ALPHA exeriment at CERN has managed to trap 300 antiatoms in the CERN Antiproton Decelerator for over 16 minutes, allowing them to be measured, studied, and compared to hydrogen atoms.

“We can keep the antihydrogen atoms trapped for 1000 seconds,” explained ALPHA spokesperson Jeffrey Hangst of Aarhus University. “This is long enough to begin to study them – even with the small number that we can catch so far.”
