On the role of density fluctuations in the core turbulent transport of Wendelstein 7-X
D. Carralero, T. Estrada, E. Maragkoudakis +19
A recent characterization of core turbulence carried out with a Doppler reflectometer in the optimized stellarator Wendelstein 7-X (W7-X) found that discharges achieving high ion t…
Physics design point of high-field stellarator reactors
J. A. Alonso, I. Calvo, D. Carralero +4
The ongoing development of electromagnets based on High Temperature Superconductors has led to the conceptual exploration of high-magnetic-field fusion reactors of the tokamak type…
A model for the fast evaluation of prompt losses of energetic ions in stellarators
J. L. Velasco, I. Calvo, S. Mulas +4
A good understanding of the confinement of energetic ions in non-axisymmetric magnetic fields is key for the design of reactors based on the stellarator concept. In this work, we d…
Fast simulations for large aspect ratio stellarators with the neoclassical code KNOSOS
J. L. Velasco, I. Calvo, F. I. Parra +5
In this work, a new version of KNOSOS is presented. KNOSOS is a low-collisionality radially-local, bounce-averaged neoclassical code that is extremely fast, and at the same time, i…
An experimental characterization of core turbulence regimes in Wendelstein 7-X
D. Carralero, T. Estrada, E. Maragkoudakis +14
First results from the optimized helias Wendelstein 7-X stellarator (W7-X) have shown that core transport is no longer mostly neoclassical, as is the case in previous kinds of stel…
Study on impurity hole plasmas by global neoclassical simulation
Keiji Fujita, Shinsuke Satake, Masanori Nunami +3
An impurity hole observed in the Large Helical Device (LHD) is a hollow density profile of an impurity ion species formed in the core plasma where the negative (inward-pointing) am…
