    • Challenges in the extrapolation from DD to DT plasmas: experimental analysis and theory based predictions for JET-DT 

      Garcia, J.; Challis, C.; Gallart, D.; Garzotti, L.; Görler, T.; King, D.; Mantsinen, Mervi; Jet Contributors (IOP Publishing, 2016-10-27)
      Article
      Open Access
      A strong modelling program has been started in support of the future JET-DT campaign with the aim of guiding experiments in deuterium (D) towards maximizing fusion energy production in Deuterium–Tritium (DT). Some of the ...
    • 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, ...
    • Stabilization of microturbulence by fast ions n ASDEX upgrade 

      Oliveira, F.N. de; Doerk, H.; Mantsinen, M .J.; Angioni, C.; Bilato, R.; Gallart, D.; Gutiérrez-Milla, A.; Mantica, P.; Odstrcil, T.; Sáez, X.; Tardini, G.; ASDEX Upgrade Team; EUROfusion MST1 Team (Barcelona Supercomputing Center, 2017-05-04)
      Conference report
      Open Access
      The goal of the present work is to study the impact of fast ions, generated by ICRH, on microturbulence. Our methodology is similar to that in [2] and is based on extensive simulations of discharges carried out on the ASDEX ...
    • The effects of electron cyclotron heating and current drive on toroidal Alfvén eigenmodes in tokamak plasmas 

      Sharapov, S.E.; Garcia-Muñoz, M.; van Zeeland, M.A.; Bobkov, B.; Classen, I.G.J.; Ferreira, J.; Figueiredo, A.; Fitzgerald, M.; Galdon-Quiroga, J.; Gallart, D.; Geiger, Benjamin; Gonzalez-Martin, J.; Johnson, T.; Lauber, P.; Mantsinen, Mervi; Nabais, F.; Nikolaeva, V.; Rodriguez-Ramos, M.; Sanchis-Sanchez, L.; Schneider, P.A.; Snicker, A.; Vallejos, P.; AUG Team; EUROfusion MST1 Team (IOP Publishing, 2017-11-02)
      Article
      Open Access
      Dedicated studies performed for toroidal Alfvén eigenmodes (TAEs) in ASDEX-Upgrade (AUG) discharges with monotonic q-profiles have shown that electron cyclotron resonance heating (ECRH) can make TAEs more unstable. In these ...
