题 目： Prospect of plasma theory and simulation research for JA DEMO （ Dr. YAGI Masatoshi）
摘 要：In Japan, the Joint Special Design Team for Fusion DEMO contributes to develop JA DEMO as the national team. Recently, plasma theory and simulation working group has drawn up an intermediate term research plan to contribute the conceptual design of JA DEMO. In this presentation, we will briefly introduce the activity of plasma theory and simulation research for DEMO.
题 目： Interplay between fluctuation driven toroidal axisymmetric flows and resistive ballooning mode turbulence （ Dr. SETO Haruki）
摘 要：An interplay between fluctuation driven toroidal axisymmetric flows
convective cell modes) and resistive ballooning mode turbulence after the pedestal collapse is numerically studied by a four-field reduced MHD model in the BOUT++ framework. The strong flow shear sup- presses the radial transport of pressure filaments, and the pressure profile in the pedestal region is partially recovered. As a result, a secondary instability is quasi-linearly excited, which yields a secondary collapse. The subsequent damped oscillation is also analyzed by phase diagram analysis.
题 目： Characteristics of ITG turbulence and associated global profile
formation in flux-driven gyrokinetic simulation （ Dr. WANG Wei）
摘 要：Global nature of multi-scale turbulence is of specifically importance in
understanding and evaluating transport levels in Tokamak plasmas. Based on flux-driven gyrokinetic simulations using GKNET, characteristics of ITG turbulence and associated global profile formation are discussed through several approaches including Fourier-based analyses and the newly developed size-PDF analysis
