The physics of ELM-free regimes in EUROfusion tokamaks
M. G. Dunne, M. Faitsch, O. Sauter +25
The development of operational scenarios without large Type-I ELMs is of utmost importance for the stable operation and longevity of future tokamaks. The EUROfusion tokamak exploit…
Turbulent Nature of the Quasicontinuous Exhaust Regime for Fusion Plasmas
Kaiyu Zhang, Wladimir Zholobenko, Andreas Stegmeir +5
We demonstrate a turbulence mechanism that reconciles high plasma confinement with efficient heat exhaust -- a central challenge for fusion energy. Global two-fluid turbulence simu…
A quasi-continuous exhaust scenario for a fusion reactor: the renaissance of small edge localized modes
G. F. Harrer, M. Faitsch, L. Radovanovic +13
Tokamak operational regimes with small edge localized modes (ELMs) could be a solution to the problem of large transient heat loads in future fusion reactors because they provide q…
I-mode pedestal relaxation events in the Alcator C-Mod and ASDEX Upgrade tokamaks
D. Silvagni, J. L. Terry, W. McCarthy +13
In some conditions, I-mode plasmas can feature pedestal relaxation events (PREs) that transiently enhance the energy reaching the divertor target plates. To shed light into their a…
I-mode pedestal relaxation events at ASDEX Upgrade
D. Silvagni, T. Eich, T. Happel +16
The I-mode confinement regime can feature small edge temperature drops that can lead to an increase in the energy deposited onto the divertor targets. In this work, we show that th…
On the role of filaments in perpendicular heat transport at the Scrape-off Layer
D. Carralero, S. Artene, M. Bernert +9
In this work we carry out quantitative measurements of particle and heat transport associated to SOL filaments in a tokamak, and relate density shoulder formation to the advection…
Global scaling of the heat transport in fusion plasmas
Sara Moradi, Johan Anderson, Michele Romanelli +2
A global heat flux model based on a fractional derivative of plasma pressure is proposed for the heat transport in fusion plasmas. The degree of the fractional derivative of the he…
