Vielversprechende Computersimulationen für Stellarator-Plasmen

Weg zu höherer Wärmeisolation des Plasmas beschrieben / Senkung der Plasma-Turbulenz

(PresseBox) (Garching, )
Zur theoretischen Beschreibung der Turbulenz im Plasma von Fusionsanlagen des Typs Tokamak hat sich der im Max-Planck-Institut für Plasmaphysik (IPP) in Garching entwickelte Turbulenzcode GENE (Gyrokinetic Electromagnetic Numerical Experiment) bestens bewährt. Für die komplexere Geometrie der Anlagen vom Typ Stellarator erweitert, weisen die Computersimulationen mit GENE jetzt auf eine neue Methode hin, die Plasma-Turbulenz in Stellarator-Plasmen zu reduzieren. Dies könnte die Effizienz eines künftigen Fusionskraftwerks deutlich erhöhen.

Für die Fusionsforscher des IPP, die ein Kraftwerk nach dem Vorbild der Sonne entwickeln wollen, ist die Wirbelbildung in ihrem Brennstoff – einem Wasserstoffplasma – ein zentrales Forschungsthema.
