The JT-60SA project has been implemented for the purpose of an early realization of fusion
energy. With a powerful and versatile NBI and ECRF system, a flexible plasma-shaping …

The development of reduced models provide efficient methods that can be used to perform
short term experimental data analysis or narrow down the parametric range of more …

Abstract Theory-based scaling laws of the near and far scrape-off layer (SOL) widths are
analytically derived for L-mode diverted tokamak discharges by using a two-fluid model. The …

The effect of triangularity on tokamak boundary plasma turbulence is investigated using
global, flux-driven, three-dimensional, two-fluid simulations. The simulations show that …

Wall conditioning is essential in tokamak and stellarator research to achieve plasma
performance and reproducibility. This paper presents an overview of recent conditioning …

Controlled particulate injections from the PPPL impurity powder dropper (IPD) into the Large
Helical Device have demonstrated positive effects on the wall conditions on both an intra …

The impact of fast ions on a trapped electron mode (TEM) is extensively analysed by linear
and nonlinear gyrokinetic simulations for a JT-60U plasma at high and low magnetic shear …

When the working gas of a negative ion source is changed from hydrogen to its isotope,
deuterium, an'isotope effect'is observed; namely, several plasma characteristics such as the …

JT-60SA, the largest tokamak that will operate before ITER, has been designed and built
jointly by Japan and Europe, and is due to start operation in 2020. Its main missions are to …

The stability with respect to a peeling–ballooning mode (PBM) was investigated numerically
with extended MHD simulation codes in JET, JT-60U and future JT-60SA plasmas. The …
