Selected as an Editor’s Pick, this article uncovers unexpected interactions between two types of instabilities in hot plasmas and demonstrates, for the first time, the capability of an advanced simulation code to accurately model these phenomena in the cylindrical SPEKTRE experiment at IJL.
Abstract
To produce energy through nuclear fusion, a gas of ionized atoms (called plasma) must be heated to extreme temperatures and confined using magnetic fields. But plasma is naturally unstable: it develops turbulent fluctuations that cause heat losses, slowing down the fusion reaction.
