Characterizing the temporal evolution of Biermann-battery-driven magnetic reconnection in laser-ablated plasmas
T. Morita, Y. Muramoto, S. Isayama +30
This paper presents an experimental investigation of magnetic reconnection between two laser-produced expanding plasmas, focusing on the quantitative evaluation of the reconnection…
Impact of geodesic curvature on zonal flow generation in magnetically confined plasmas
Motoki Nakata, Seikichi Matsuoka
The impact of magnetic geometry on zonal-flow generation in ion temperature gradient driven turbulence is investigated by means of linear and nonlinear gyrokinetic simulations. The…
Gyrokinetic turbulent transport simulations on steady burning condition in D-T-He plasmas
Motoki Nakata, Mitsuru Honda
Ion temperature gradient(ITG) and trapped electron modes(TEM) driven turbulent transport in an ITER-like plasma is investigated by means of multi-species gyrokinetic Vlasov simulat…
Isotope Effects on TEM-driven Turbulence and Zonal Flows in Helical and Tokamak Plasmas
Motoki Nakata, Masanori Nunami, Hideo Sugama +1
Impacts of isotope ion mass on trapped electron mode (TEM) driven turbulence and zonal flows in magnetically confined fusion plasmas are investigated. Gyrokinetic simulations of TE…
Nonlinear entropy transfer via zonal flows in gyrokinetic plasma turbulence
Motoki Nakata, Tomo-Hiko Watanabe, Hideo Sugama
Nonlinear entropy transfer processes in toroidal ion temperature gradient (ITG) and electron temperature gradient (ETG) driven turbulence are investigated based on the gyrokinetic…
Conceptual design of Thomson scattering system with high wavelength resolution in magnetically confined plasmas for electron phase-space measurements
Kentaro Sakai, Kentaro Tomita, Takeo Hoshi +4
We discuss the conceptual design of a spatially-resolved spectroscopy system of Thomson scattering with high wavelength resolution capable of measuring the shape of electron veloci…
