Journal ArticleDOI
Application of superconducting magnet energy storage to improve power system dynamic performance
TL;DR: The application of superconducting magnet energy storage (SMES) to the stabilization of a power system with long-distance bulk power transmission lines which has the problem of poorly damped power oscillations is presented in this paper.
Journal ArticleDOI
Terahertz radiation from superconducting YBa2Cu3O7−δ thin films excited by femtosecond optical pulses
Masanori Hangyo,S. Tomozawa,Yoshishige Murakami,Masayoshi Tonouchi,Masahiko Tani,Zhen Wang,Kiyomi Sakai,Seiji Nakashima +7 more
TL;DR: In this paper, the characteristics of the radiation are studied and the radiation mechanism is ascribed to the ultrafast supercurrent modulation by the laser pulses, which induce the nonequilibrium superconductivity.
Journal ArticleDOI
Ultrashort Electromagnetic Pulse Radiation from YBCO Thin Films Excited by Femtosecond Optical Pulse
Masayoshi Tonouchi,Masahiko Tani,Zhen Wang,Kiyomi Sakai,S. Tomozawa,Masanori Hangyo,Yoshishige Murakami,Shin-ichi Nakashima +7 more
TL;DR: In this paper, the supercurrent transient is created by the excitation of the supercarriers into quasiparticles with a femtosecond laser pulse, and freely propagated electromagnetic pulses are measured and characterized.
Journal ArticleDOI
Simultaneous Active and Reactive Power Control of Superconducting Magnet Energy Storage Using GTO Converter
TL;DR: In this article, a gate turn-off thyristor (GTO) converter is used to control reactive power in a superconducting magnet energy storage (SMES) in the wide range between lagging and leading phases.
Journal ArticleDOI
Enhanced THz radiation from YBCO thin film bow-tie antennas with hyper-hemispherical MgO lens
Masayoshi Tonouchi,Masahiko Tani,Zhen Wang,K. Sakai,Masanori Hangyo,N. Wada,Yoshishige Murakami +6 more
TL;DR: In this paper, the power enhancement of terahertz (THz) radiation from YBCO thin films was demonstrated with an ultra wideband electromagnetic pulse, which contains frequency components over 3 THz, was excited by ultrafast supercurrent modulation with femtosecond optical pulse irradiation.
