CERN experiment provides first glimpse inside cold antihydrogen
24 Oct 2002
The ATRAP1 experiment at the Antiproton Decelerator at CERN2 has detected and measured large numbers of cold antihydrogen atoms. Relying on ionization of the cold antiatoms when they pass through a strong electric field gradient, the ATRAP measurement provides the first glimpse inside an antiatom, and the first information about the physics of antihydrogen. The results have been accepted for publication in Physical Review Letters.
