first-ever beam of antihydrogen atoms

CERN announced that its ASACUSA experiment has produced the world's first-ever beam of antihydrogen atoms. Such beams will make possible a couple of tests that seek to answer one of the biggest questions in physics: Why is there more matter than antimatter?

"The ASACUSA experiment at CERN has succeeded for the first time in producing a beam of antihydrogen atoms. In a paper published today in Nature Communications, the ASACUSA collaboration reports the unambiguous detection of 80 antihydrogen atoms 2.7 metres downstream of their production, where the perturbing 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." in CERN Press Office

LHC First Beam on 10 September 2008

Primeira experiência do LHC

Geneva, 10 de Setembro de 2008. O primeiro teste com um feixe de milhões de protões no acelerador LHC (Large Hadron Collider) do Laboratório Europeu de Física de Partículas (CERN) foi bem sucedido, percorrendo os 27 quilómetros às 10h28min desta manhã. Este evento histórico marca um momento chave na transição, com mais de duas décadas de preparação, para uma nova era de descobertas científicas.

First beam in the LHC - accelerating science

Geneva, 10 September 2008. The first beam test, with millions of protons, in the Large Hadron Collider (LHC) at CERN was successfully. The beam covered a distance around the full 27 kilometres at 10h28 this morning. This historic event marks a key moment in the transition to a new era of scientific discovery.
