Gyrotrons for High-Power Terahertz Science and Technology at FIR UF
Toshitaka Idehara, Svilen Petrov Sabchevski
In this paper, we present the recent progress in the development of a series of gyrotrons at FIR UF that have opened the road to many novel applications in the high-power Terahertz…
Finite-Bandwidth Resonances of High-Order Axial Modes (HOAM) in a Gyrotron Cavity
Svilen Sabchevski, Toshitaka Idehara
Finite-bandwidth resonances of high-order axial modes (HOAM) in an open gyrotron cavity are studied numerically using the GYROSIM problem-oriented software package for modelling, s…
A Dual-Beam Irradiation Facility for a Novel Hybrid Cancer Therapy
Svilen Sabchevski, Toshitaka Idehara, Shintaro Ishiyama +2
In this paper we present the main ideas and discuss both the feasibility and the conceptual design of a novel hybrid technique and equipment for an experimental cancer therapy base…
Direct Observation of the Hyperfine Transition of the Ground State Positronium
T. Yamazaki, A. Miyazaki, T. Suehara +7
We report the first direct measurement of the hyperfine transition of the ground state positronium. The hyperfine structure between ortho-positronium and para-positronium is about…
First direct measurement of positronium hyperfine splitting with sub-THz light
T. Yamazaki, A. Miyazaki, T. Suehara +8
Positronium is an ideal system for the research of the bound state QED. The hyperfine splitting of positronium (Ps-HFS, about 203 GHz) is an important observable but all previous m…
Detection of the Direct Hyperfine Transition of Positronium Atoms using sub-THz High-power Radiation
T. Suehara, A. Miyazaki, T. Yamazaki +11
Hyperfine splitting of positronium is an important parameter for particle physics. This paper gives experimental techniques and results of R&D studies of our experiment to observe…
