• Are magnetic resonances practical transport controllers in fusion plasmas? the TJ-II experience 

      López-Bruna, D.; Romero, J.; Vargas-Blanco, Iván (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 

      Asenjo, J.; Carvajal-Godínez, Johan; González-Gómez, J.; Soto-Soto, C.; Piedra, C.; Barillas-Mora, Laura; Mora-Meléndez, Jaime; Otárola-Zúñiga, Carlos; Zamora-Picado, Esteban; Vargas-Blanco, Iván (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 ...
    • Transport, stability and plasma control studies in the TJ-II stellarator 

      Sánchez, J.; Alegre, D.; Alonso, A.; Alonso, J.; Alvarez, P.; Arévalo, J.; Ascasíbar, E.; Baciero, A.; Baiao, D.; Barcala, J. (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 ...
