An effective disruption mitigation system in a tokamak reactor should limit the exposure of
the wall to localized heat losses and to the impact of high current runaway electron beams …

Non-axisymmetric simulations of the current quench phase of ITER disruptions are key to
predict asymmetric forces acting into the ITER wall. We present for the first time such …

On the origin of the plasma current spike during a tokamak disruption and its relation with
magnetic stochasticity - IOPscience Skip to content IOP Science home Accessibility Help …

In ITER, disruption-born runaway electrons (REs), unless mitigated, are expected to form a
several Mega-Ampere beam that ultimately intercepts the first wall leading to melting of the …

Abstract In Izzo et al (2022 Nucl. Fusion 62 096029), state-of-the-art modeling of thermal and
current quench (CQ) magnetohydrodynamics (MHD) coupled with a self-consistent evolution …

Benign termination of mega-ampere (MA) level runaway current has been convincingly
demonstrated in recent JET and DIII-D experiments, establishing it as a leading candidate …

Energetic particle (EP)-driven instabilities will be of strongly increased relevance in future
burning plasmas as the EP pressure will be very large compared to the thermal plasma …

In the event of a tokamak disruption in a DT plasma, fusion-born alpha particles take several
milliseconds longer to thermalise than the background. As the damping rates drop …

Characteristics of the early current quench (CQ) time in mitigated disruptions are studied for
a full-current (5.5 MA) scenario in the JT-60SA superconducting tokamak. Self-consistent …

We present test-particle simulations of electrons during a nonlinear magnetohydrodynamic
(MHD) simulation of a type-I edge localized mode to explore the effect of an eruptive plasma …
