In order to test CPT symmetry between antihydrogen and its counterpart hydrogen, the ASACUSA collaboration plans to perform high precision microwave spectroscopy of ground-state hyperfine splitting of antihydrogen atom in-flight. We have developed an apparatus (“cusp trap”) which consists of a superconducting anti-Helmholtz coil and multiple ring electrodes. [...]

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. [...]

Synthesis of Cold Antihydrogen in a Cusp Trap / Enomoto, Y (Wako, RIKEN) ; Kuroda, N (Tokyo, U.) ; Michishio, K (Tokyo U. of Sci.) ; Kim, C H (Tokyo, U.) ; Higaki,H (ADSM, Hiroshima) ; Nagata, Y (Wako, RIKEN) ; Kanai, Y (Wako, RIKEN) ; Torii, H A (Tokyo, U.) ; Corradini, M (Brescia U. ; INFN, Brescia) ; Leali, M (Brescia U. ; INFN, Brescia) et al.
We report here the first successful synthesis of cold antihydrogen atoms employing a cusp trap, which consists of a superconducting anti-Helmholtz coil and a stack of multiple ring electrodes. This success opens a new path to make a stringent test of the CPT symmetry via high precision microwave spectroscopy of ground-state hyperfine transitions of antihydrogen atoms..
