Sensitivity of a low-shear heliotron configuration to localised ferrite perturbations
A. Matsuyama, Y. Nakamura, S. Inagaki +10
The influence of ferritic steel on low-shear stellarator/heliotron magnetic configurations is investigated for the Heliotron J device using a point dipole magnetisation model. By n…

Integrated Observation of Isotope-Dependent Turbulence, Zonal Flow, and Turbulence-Driven Transport
Shinsuke Ohshima, Hiroyuki Okada, Shinji Kobayashi +7
To address the long-standing unresolved issue of "isotope effect" in plasma transport, this study investigates the hydrogen/deuterium (H/D) isotope dependence of a nonlinear turbul…

Development of the poloidal Charge eXchange Recombination Spectroscopy system in Heliotron J
X. X. Lu, S. Kobayashi, T. Harada +22
A Charge eXchange Recombination Spectroscopy (CXRS) system designed to measure the poloidal rotation velocity is developed in Heliotron J. The poloidal CXRS system measures the car…
