  • Pellet refuelling of particle loss due to ELM mitigation with RMPs in the ASDEX Upgrade tokamak at low collisionality

    Valovič, M.; Lang, P.T.; Kirk, A.; Suttrop, W.; Cavedon, M.; Cseh, G.; Dunne, M.; Fischer, L.R.; Garzotti, L.; Guimarais, L.; Kocsis, G.; Mlynek, A.; Plőckl, B.; Scannell, R.; Szepesi, T.;... (2016)
    Projects: EC | EUROfusion (633053)
    The complete refuelling of the plasma density loss (pump-out) caused by mitigation of Edge Localised Modes (ELMs) is demonstrated on the ASDEX Upgrade tokamak. The plasma is refuelled by injection of frozen deuterium pellets and ELMs are mitigated by external resonant magnetic perturbations (RMPs). In this experiment relevant dimensionless parameters, such as relative pellet size, relative RMP amplitude and pedestal collisionality are kept at the ITER like values. Refuelling of density pump o...

    Flow damping in stellarators close to quasisymmetry

    Calvo, Ivan; Parra, Felix I.; Velasco, J. L.; Alonso, J. Arturo (2014)
    Projects: EC | EUROfusion (633053)
    Quasisymmetric stellarators are a type of optimized stellarators for which flows are undamped to lowest order in an expansion in the normalized Larmor radius. However, perfect quasisymmetry is impossible. Since large flows may be desirable as a means to reduce turbulent transport, it is important to know when a stellarator can be considered to be sufficiently close to quasisymmetry. The answer to this question depends strongly on the size of the spatial gradients of the deviation from quasisy...

    Tungsten dust remobilization under steady-state and transient plasma conditions

    Ratynskaia, S.; Tolias, P.; de Angeli, M.; Weinzettl, V.; Matejicek, J.; Bykov, I.; Rudakov, D. L.; Vignitchouk, L.; E. Thorén; Riva, G.; Ripamonti, D.; Morgan, T.; R. Panek; De Temmerman, G. (2017)
    Projects: EC | EUROfusion (633053)
    Remobilization is one of the most prominent unresolved fusion dust-relevant issues, strongly related to the lifetime of dust in plasma-wetted regions, the survivability of dust on hot plasma-facing surfaces and the formation of dust accumulation sites. A systematic cross-machine study has been initiated to investigate the remobilization of tungsten micron-size dust from tungsten surfaces implementing a newly developed technique based on controlled pre-adhesion by gas dynamics methods. It has ...

    Optimizing stellarators for large flows

    Calvo, Ivan; Parra, Felix I.; Alonso, J. Arturo; Velasco, J. L. (2014)
    Projects: EC | EUROfusion (633053)
    Plasma flow is damped in stellarators because they are not intrinsically ambipolar, unlike tokamaks, in which the flux-surface averaged radial electric current vanishes for any value of the radial electric field. Only quasisymmetric stellarators are intrinsically ambipolar, but exact quasisymmetry is impossible to achieve in non-axisymmetric toroidal configurations. By calculating the violation of intrinsic ambipolarity due to deviations from quasisymmetry, one can derive criteria to assess w...

    Plasma–wall interaction studies within the EUROfusion consortium: progress on plasma-facing components development and qualification

    Brezinsek , S.; Coenen , J.; Schwarz-Selinger , T.; Schmid , K.; Kirschner , A.; Hakola , A.; Tabares , L.; van der Meiden , J.; Mayoral , M.; Reinhart , M.; Tsitrone , E.; Ahlgren , T.; Aints , M.; Airila , M.; Almaviva , S.;... (2017)
    Projects: EC | EUROfusion (633053)
    The provision of a particle and power exhaust solution which is compatible with first-wall components and edge-plasma conditions is a key area of present-day fusion research and mandatory for a successful o peration of ITER and DEMO. The work package plasma-facing components (WP PFC) within the European fusion programme complements with laboratory experiments, i.e. in linear plasma devices, electron and ion beam loading f acilities, the studies performed in toroidally confined magnetic device...

    Theoretical description of heavy impurity transport and its application to the modelling of tungsten in JET and ASDEX Upgrade

    Casson, F. J.; Angioni, C.; Belli, E. A.; Bilato, R.; Mantica, P.; Odstrcil, T.; Puetterich, T.; Valisa, M.; Garzotti, L.; Giroud, C.; Hobirk, J.; Maggi, C. F.; Mlynar, J.; Reinke, M. L.; contributors, JET EFDA;... (2014)
    Projects: EC | EUROfusion (633053)
    Recent developments in theory-based modelling of core heavy impurity transport are presented, and shown to be necessary for quantitative description of present experiments in JET and ASDEX Upgrade. The treatment of heavy impurities is complicated by their large mass and charge, which result in a strong response to plasma rotation or any small background electrostatic field in the plasma, such as that generated by anisotropic external heating. These forces lead to strong poloidal asymmetries o...

    Mitigating the hosing instability in relativistic laser-plasma interactions

    Ceurvorst, L; Ratan, N; Levy, M C; Kasim, M F; Sadler, J; Scott, R H H; Trines, R M G M; Huang, T W; Skramic, M; Vranic, M; Silva, L O; Norreys, P A (2016)
    Projects: EC | EUROfusion (633053)
    A new physical model of the hosing instability that includes relativistic laser pulses and moderate densities is presented and derives the density dependence of the hosing equation. This is tested against two-dimensional particle-in-cell simulations. These simulations further examine the feasibility of using multiple pulses to mitigate the hosing instability in a Nd:glass-type parameter space. An examination of the effects of planar versus cylindrical exponential density gradients on the hosi...

    Fe + ion irradiation induced changes in structural and magnetic properties of iron films

    Papamihail, K.; Mergia, K.; Ott, F.; Serruys, Yves; Speliotis, Th.; Apostolopoulos, G.; Messoloras, S. (2016)
    Projects: EC | EUROfusion (633053)
    490keV Fe+ ion irradiation of 200nm thick Fe films was found to induce both structural and magnetic changes. Both, the lattice constant and the grain size increase as a function of dose and both properties follow the same power law. Irradiation induces a depth dependent magnetic profile consisting of two sublayers. The top Fe sublayer has a magnetic moment higher than that of the Fe before the irradiation whereas the bottom sublayer lower. The two sublayers are connected with the effects of F...

    New Insights Into The Generalized Rutherford Equation For Nonlinear Neoclassical Tearing Mode Growth From 2D Reduced Mhd Simulations

    Westerhof, Egbert; Pratt, Jane; de Blank, Hugo J. (2016)
    Publisher: Zenodo
    Projects: EC | EUROfusion (633053)
    Two dimensional reduced MHD simulations of neoclassical tearing mode growth and suppression by ECCD are performed. The perturbation of the bootstrap current density and the EC drive current density perturbation are assumed to be functions of the perturbed flux surfaces. In the case of ECCD, this implies that the applied power is flux surface averaged to obtain the EC driven current density distribution. The results are consistent with predictions from the generalized Rutherford equation using...
