Antimatter trap tightens its grip

Physicists working on the ALPHA experiment at CERN, who in 2010 became the first to capture and store atoms of antimatter for long enough to examine them in detail, have made another significant advance.

The ALPHA-2 apparatus - facilitating experimentation with trapped antihydrogen

R. Akbari, B. X. R. Alves, C.J. Baker +58 more

This paper describes the ALPHA-2 apparatus, used at the CERN Antiproton Decelerator facility for the study of trapped antihydrogen atoms. Details of both the construction and performance are included. Prominence is given to both the new and the improved features, with respect to the original ALPHA assembly, of the apparatus including a stand-alone antiproton catching trap, the traps used to mix antiparticles to produce the anti-atoms, the magnetic atom trap used to hold some of them, and access for laser light to facilitate excitation of the antihydrogen 1 S -2 P and 1 S -2 S transitions.This paper describes the ALPHA-2 apparatus, used at the CERN Antiproton Decelerator facility for the study of trapped antihydrogen atoms.
