| Research Abstract |
Aiming for the creation of toroidal antimatter plasmas, the dynamics of positrons in a dipole magnetic field was numerically and experimentally investigated. High energy positrons supplied from a radioactive source have chaotic long orbit lengths in the dipole field, which can be applied to an efficient injection method of positrons into a confinement region. A proof-of-principle experiment was conducted by using a small Na-22 source and a gamma-ray coincidence measurement system in RT-1.
