Beschreibungen/Notizen

• The ASACUSA collaboration has developed a cusp trap scheme to realize an in-flight high precision microwave spectroscopy of ground-state hyperfine splitting of antihydrogen ( H ̄) for a stringent test of CPT symmetry. Cold H ̄ atoms were successfullysynthesized by employing a cusp trap which consisted of a superconducting anti-Helmholtz coil and a stack of ring electrodes. This was achieved with an antiproton ( p ̄) accumulator, MUSASHI, and a positron ( e +) accumulator. The principal quantum number and the time evolution of H ̄ synthesis were investigated. The latest progress was also presented.
