Abstract: (Physical Society of Japan)
The ASACUSA CUSP experiment plans a high precision spectroscopy of the ground-state hyperfine splitting of antihydrogen to test CPT symmetry. To perform this, a Rabi-like antiatomic beam method has been developed with a novel double-cusp trap. Antihydrogen atoms were synthesized in the double-cusp trap by directly injecting antiprotons from an accumulation trap into a positron plasma. By adjusting the energy difference between the incoming antiproton beam and the positron plasma, a high-rate production of antihydrogen atoms was observed.
