Unveiling the properties of edge harmonic oscillation is one of the major pursuits to understand complex systems in plasma physics. The authors present measurements at the JT-60U tokamak that show direct observations of peeling modes in quiescent hig

Heat-resistant in-vessel components, i.e., a heat sink, a front-end optics housing, and a diagnostic window have been designed in terms of heat-handling capability and thermal stress and mechanical stress by using a finite element method code. The he

We have developed a denoising autoencoder based neural network (NN) method to determine a spectral line intensity with an uncertainty lower than the uncertainty determined by fitting the spectral line. The NN method processes the measured raw spectra

Disruption is a critical phenomenon in a tokamak reactor. Although disruption causes serious damage to the reactor, its physical mechanism remains unclear. To realize a tokamak reactor, it is necessary to understand and control the disruption phenome
Explosive dynamical events in controlled-nuclear-fusion devices (known as edge-localized modes) display many similarities to solar-flare events on the sun, revealing a new connection between laboratory plasma physics and astronomy. However, to date t

Helical cores (HCs) in plasmas are one of the important phenomena because the helical structure affects impurity transport and induces loss of confined energetic particles or loss of toroidal momentum. Substantial studies on experimental observation
