ASACUSA experiment produces first beam of antihydrogen atoms at CERN


The ASACUSA experiment at CERN has succeeded for the first time in producing a beam of antihydrogen atoms. In a paper published in Nature Communications, the ASACUSA collaboration reports the unambiguous detection of 80 antihydrogen atoms 2.7 meters downstream of their production, where the influence of the magnetic fields used initially to produce the antiatoms is small. This result is a significant step towards precise hyperfine spectroscopy of antihydrogen atoms. The feat will help them test whether these atoms differ from their matter counterparts, which could give scientists clues about how our universe formed. Primordial antimatter has so far never …continue reading
