  • Computation of the weakly relativistic plasma dispersion functions using superasymptotic and hyperasymptotic expansions 
    Pavlov, S.S.; Castejón, F.; Tereshchenko, M. (2010)
    A new method to compute the weakly relativistic plasma dispersion functions for complex argument is presented. It is demonstrated that Jacobi fractions represent those functions asymptotically for z→ ∞ in the upper semi-plane.
  • Discrimination between magnetic shear and toroidal electric field effects in TJ-II plasmas 
    López-Bruna, D.; Romero, J. A.; Castejón, F.; Estrada, T.; Ascasíbar, E. (Вопросы атомной науки и техники, 2002)
    The response of TJ-II plasmas to an induced toroidal electric field, Eǿ , was studied in past experiments with the aid of Ohmic inducted current. It was found that positive induced plasma current, Ip, degrades the confinement ...
  • Effective evaluation of the exact relativistic plasma dispersion functions 
    Pavlov, S.S.; Castejón, F.; Tereshchenko, M. (Вопросы атомной науки и техники, 2013)
    A new effective evaluation method of the exact relativistic plasma dispersion functions in the real and complex regions is given on the basis of nonsingular forms of Cauchy or Cauchy-type integrals and the Euler-Maclaurin formula.
  • Experimental intertwinement of radial electric fields, fluctuations and transport with density in TJ-II plasmas 
    López-Bruna, D.; Alonso, A.; Blanco, E.; Calvo, I.; Castejón, F.; Estrada, T.; Herranz, J.; Hidalgo, C.; Krupnik, L.; Melnikov, A.; van Milligen, B.; Pedrosa, M. A.; Vargas, V. I. (Вопросы атомной науки и техники, 2006)
    Traditionally, three transport regions have been considered in the TJ-II stellarator: the plasma core, where heat deposition physics seems to dominate transport and therefore the radial electric field; a confinement or ...
  • Fast computation of the exact plasma dispersion functions 
    Pavlov, S.S.; Castejón, F.; Cappa, Á.; Tereshchenko, M. (Вопросы атомной науки и техники, 2009)
    The paper is concerned with a computation of the exact relativistic plasma dispersion functions for complex argument z = x + iy in the region Q : y ≥ 0 on the base the theory of the continued fractions of Jacobi. It is ...
  • Latest physics results of TJ-II flexible heliac 
    Castejón, F.; Alejaldre, C.; Alonso, J.; Almoguera, L.; Ascasíbar, E.; Baciero, A.; Balbín, R.; Blaumoser, M.; Botija, J.; Brañas, B.; de la Cal, E.; Cappa, A.; Carrasco, R.; Cepero, J.R.; Cremy, C.; Doncel, J.; Eguilior, S.; Estrada, T.; Fernández, A.; Fuentes, C.; García, A.; García-Cortés, I.; Guasp, J.; Herranz, J.; Hidalgo, C.; Jiménez, J.A.; Kirpitchev, I.; Krivenski, V.; Labrador, I.; Lapayese, F.; Likin, K.; Liniers, M.; López-Fraguas, A.; López-Sánchez, A.; de la Luna, E.; Martín, R.; Martínez-Laso, L.; Medrano, M.; Méndez, P.; McCarthy, K.J.; Medina, F.; van Milligen, B.; Ochando, M.; Pacios, L.; Pastor, I.; Pedrosa, M.A.; de la Peña, A.; Portas, A.; Qin, J.; Rodríguez-Rodrigo, L.; Salas, A.; Sánchez, E.; Sánchez, J.; Tabarés, F.; Tafalla, D.; Tribaldos, V.; Vega, J.; Zurro, B. (Вопросы атомной науки и техники, 2000)
    This paper is devoted to the presentation of the most relevant recent Physics results obtained in the TJ-II flexible heliac. Firstly ECRH modulation and plasma breakdown studies are summarised; then the particle control ...
  • Limits of applicability of the weakly relativistic approximation in the theory of plasma waves 
    Pavlov, S.S.; Castejón, F. (Вопросы атомной науки и техники, 2018)
    The more general weakly-relativistic plasma dispersion functions are introduced and discussed in the frame of the fully relativistic approach for the theory of plasma waves.
  • Perturbative transport experiments on TJ-II Flexible Heliac 
    Castejón, F.; Ascasíbar, E.; Alejaldre, C.; Alonso, J.; Almoguera, L.; Baciero, A.; Balbín, R.; Blanco, E.; Blaumoser, M.; Botija, J.; Brañas, B.; Cappa, A.; Carrasco, R.; Cepero, J.R.; Chmyga, A.A.; Doncel, J.; Dreval, N.B.; Eguilior, S.; Eliseev, L.; Estrada, T.; Fedyanin, O.; Fernández, A.; Fontdecaba, J.M.; Fuentes, C.; García, A.; García-Cortés, I.; Gonçalves, B.; Guasp, J.; Herranz, J.; Hidalgo, A.; Hidalgo, C.; Jiménez, J.A.; Kirpitchev, I.; Khrebtov, S.M.; Komarov, A.D.; Kozachok, A.S.; Krupnik, L.; Lapayese, F.; Likin, K.; Liniers, M.; López-Bruna, D.; López-Fraguas, A.; López-Rázola, J.; López-Sánchez, A.; de la Luna, E.; Malaquias, A.; Martín, R.; Medrano, M.; Melnikov, A.V.; Méndez, P.; McCarthy, K.J.; Medina, F.; van Milligen, B.; Nedzelskiy, I.S.; Ochando, M.; Pacios, L.; Pastor, I.; Pavlov, S.S.; Pedrosa, M.A.; de la Peña, A.; Petrov, A.; Petrov, S.; Portas, A.; Romero, J.; Rodríguez-Rodrigo, L.; Salas, A.; Sánchez, E.; Sánchez, J.; Sarksian, K.; Schchepetov, S.; Skvortsova, N.; Tabarés, F.; Tafalla, D.; Tribaldos, V.; Varandas, C.F.A.; Vega, J.; Zurro, B. (Вопросы атомной науки и техники, 2002)
    Transport properties of TJ-II are explored performing perturbative experiments and taking advantage of TJ-II flexibility. Rotational transform can be varied in a wide range, which allows one to introduce low order rationals ...
  • Predicted and validated theoretical results for stellarators in the frame of eurofusion WPS2 
    Castejón, F. (Вопросы атомной науки и техники, 2018)
    The main results of the work performed under EUROfusion for stellarator optimization are shown. Physics and engineering activities are undertaken in order that both are considered from the very beginning and the physics ...
  • Stellarator theory studies and optimization under EUROfusion 
    Castejón, F. (Вопросы атомной науки и техники, 2017)
    The WPS2 EUROfusion work package entitled “Stellarator Optimization: Theory, Development, Modelling and Engineering” and is targeted to the development of tools for designing new optimised configurations and to support ...
  • Transport and plasma control in the Tj-Ii stellarator 
    Castejón, F. (Вопросы атомной науки и техники, 2016)
    This paper shows the effect of 3D geometry on transport and plasma control in the TJ-II stellarator. The fuelling and impurity transport are affected due to the enhancement of neoclassical (NC) transport and subsequent ...
