    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, ...
  • Non-linear MHD Simulation s of Pellet Triggered ELMs in JET and ASDEX Upgrade tokamaks 

    Futatani, Shimpei; Pamela, S.; Huijsmans, G.T.A.; Garzotti, L.; Frigione, D.; Loarte, D.; Hoelzl, M.; Lang, P.T.; Kocsis, G.; Orain, F.; Dunne, M.; Lessig, A.; Mantsinen, Mervi; EUROfusion MST1 Team; ASDEX Upgrade Team; JET Contributors (2016-07-08)
    Open Access
    ITER operation in its high fusion performance DT scenarios relies on the achievement of the H-mode confinement regime, which is expected to lead to the quasi-periodic triggering of ELMs (Edge Localized Modes). ...
  • 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, B.; 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)
    Restricted access - publisher's policy
    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 ...
