    • Electromagnetic turbulence suppression by energetic particle driven modes 

      Siena, Alessandro di; Görler, Tobias; Bañon Navarro, Alejandro; Biancalani, Alessandro; Bilato, Roberto; Mantsinen, Mervi J.; Oliveira Lopes, Felipe Nathan de; Jenko, Frank (IOP Publishing, 2019-09)
      Article
      Open Access
      In recent years, a strong reduction of plasma turbulence in the presence of energetic particles has been reported in a number of magnetic confinement experiments and corresponding gyrokinetic simulations. While highly ...
    • Linear scaling DFT calculations for large tungsten systems using an optimized local basis 

      Mohr, Stephan; Eixarch, Marc; Amsler, Maximilian; Mantsinen, Mervi J.; Genovese, Luigi (Elsevier, 2018-05)
      Article
      Open Access
      Density functional theory (DFT) has become a standard tool for ab-initio simulations for a wide range of applications. While the intrinsic cubic scaling of DFT was for a long time limiting the accessible system size to ...
    • Nonlinear electromagnetic stabilization of ITG microturbulence by ICRF-driven fast ions in ASDEX Upgrade 

      de Oliveira, F.N.; Doerk, H.; Mantsinen, Mervi J.; Angioni, C.; Bilato, R.; Bobkov, V.; Dunne, M.; Gallart, D.; Gutiérrez-Milla, A.; Mantica, P.; Odstrcil, T.; Tardini, G.; Sáez, Xavier; ASDEX Upgrade Team; EUROfusion MST1 Team (2016-10)
      Conference lecture
      Open Access
      Electromagnetic waves in the range of Ion Cyclotron Resonance Frequencies (ICRF) have many applications in fusion devices. While their use for external heating of magnetically confined fusion plasmas is well established, ...
    • Synergetic heating of D-NBI ions in the vicinity of the mode conversion layer in H-D plasmas in JET with the ITER like wall 

      Ongena, J.; Kazakov, Ye O.; Baranov, Y.; Hellesen, C.; Eriksson, J.; Johnson, T.; Kiptily, V.G.; Mantsinen, Mervi J.; Nocente, M.; Bilato, R.; Cardinali, A.; Castaldo, C.; Crombé, K.; Czarnecka, A.; Dumont, R.; Faustin, J.; Giacomelli, L.; Goloborodko, V.; Graves, J.; Jacquet, Ph.; Krawczyk, N.; Lerche, E.; Meneses, L.; Nave, M.F.F.; Patten, H.; Schneider, M.; Van Eester, D.; Weisen, H.; Wright, J.C.; JET Contributors (EDP Sciences: EPJ Open Access, 2017-10-23)
      Article
      Open Access
      This paper discusses the extension of the ‘three-ion’ species ICRF technique for heating mixture plasmas using fast injected NBI ions as resonant ‘third’ species. In this scenario the ICRF power is absorbed by the fast ...
    • Validations of the radiation transport module NEUTRO: A deterministic solver for the neutron transport equation 

      Soba, Alejandro; Cazado, Mauricio E.; Houzeaux, Guillaume; Gutierrez Milla, Albert; Mantsinen, Mervi J.; Saez Pous, Xavier (Elsevier, 2021)
      Article
      Restricted access - publisher's policy
      We present significant improvements and validations of a deterministic neutron transport code (NEUTRO) dedicated to solving the Boltzmann Transport Equation. The code is integrated as a module in the Alya software package ...
