Abstract:
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 (H̄) for a stringent test of CPT symmetry. Cold H̄ 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 (p̄) accumulator, MUSASHI, and a positron (e+) accumulator. The principal quantum number and the time evolution of H̄ synthesis were investigated. The latest progress was also presented.
