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 ...
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 ...
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 ...
Implementation of stellarator of Costa Rica 1 SCR-1
(26th IEEE Symposium on Fusion Engineering, SOFE 2015, 2015)
The SCR-1 is a small modular stellarator designed, constructed and is being implemented at Instituto Tecnológico de Costa Rica. The project is its final phase of commissioning and it is expected to be operational in June ...
Atmospheric-Pressure Non-thermal Plasma-JET effects on PS and PE surfaces
(Institute of Physics Publishing, 2015-03)
The Atmospheric-Pressure Non-Thermal Plasma (APNTP) has become a topic of a great interest for a wide spectrum of applications in different industry branches, including the surface of treatment processes. In this work we ...
Engineering of the Stellarator of Costa Rica: SCR-1
(Institute of Physics Publishing, 2015-03)
This Paper aims at briefly describing the challenge of the design and construction of the Stellarator of Costa Rica 1 (SCR-1) [1]. The SCR-1 is a small modular Stellarator for magnetic confinement of plasma (Ro=0.238 m, ...
