By Akira Miyazaki

during this thesis, the writer develops new high-power millimeter wave options for measuring the hyperfine constitution of positronium (Ps-HFS) at once for the 1st time on the planet. oblique size of Ps-HFS within the literature may need systematic uncertainties regarding using a static magnetic box. improvement of the millimeter wave units helps the right selection of Ps-HFS through at once measuring the Breit-Wigner resonant transition from o-Ps to p-Ps with no the magnetic box. even as, the width of the measured Breit-Wigner resonance at once offers the life of p-Ps. This dimension is the 1st unique spectroscopic test related to the magnetic dipole transition and high-power millimeter waves. the improvement of a gyrotron and a Fabry-PĂ©rot hollow space is defined as delivering an efficient strength of over 20 kW, that's required to reason the direct transition from o-Ps to p-Ps. these values measured by way of the newly built millimeter wave gadget pave the way in which for studying the discrepancy saw among traditional oblique experiments on Ps-HFS and the theoretical predictions of Quantum Electrodynamics.
