TL;DR: Wendelstein 7-AS was the first modular stellarator device to test some basic elements of stellarator optimization: a reduced Shafranov shift and improved stability properties resulted in β-values up to 3.4% as discussed by the authors.
Journal ArticleDOI
Core electron-root confinement (CERC) in helical plasmas
Masayuki Yokoyama,H. Maassberg,C. D. Beidler,Victor Tribaldos,Katsumi Ida,T. Estrada,F. Castejon,Akihide Fujisawa,Takashi Minami,Takashi Shimozuma,Y. Takeiri,Andreas Dinklage,Sadayoshi Murakami,Hiroshi Yamada +13 more
TL;DR: In this paper, the core electron-root confinement (CERC) was proposed for non-axisymmetric configurations of helical devices, and the thresholds for CERC establishment were found for the collisionality and electron cyclotron heating power.
Journal ArticleDOI
Ray-tracing code TRAVIS for ECR heating, EC current drive and ECE diagnostic
TL;DR: The code is written for electron cyclotron studies with emphasis on heating, current drive and ECE diagnostic, and works with an arbitrary 3D magnetic equilibrium being applicable for both stellarators and tokamaks.
