Transport, stability and plasma control studies in the TJ-II stellarator
(Institute of Physics Publishing, 2015-07)
The main TJ-II results since 2012 are presented in this overview. Impurity confinement is studied showing an isotopic dependence of impurity confinement time, asymmetries in parallel impurity flows in TJ-II ion-root plasmas ...
Are magnetic resonances practical transport controllers in fusion plasmas? the TJ-II experience
(Institute of Physics Publishing, 2015-03)
The TJ-II stellarator is a mid-size Heliac design (high rotational transform, low magnetic shear) that allows for external control of the rotational transform profile. The long experience with locating diverse magnetic ...
Constructing a small modular stellarator in Latin America
(Institute of Physics Publishing, 2015-03)
This paper aims at briefly describing the design and construction issues of the stellarator of Costa Rica 1 (SCR-1). The SCR-1 is a small modular stellarator for magnetic confinement of plasma developed by the Plasma ...
