Highest fusion performance without harmful edge energy bursts in tokamak

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-11 (2024)

Abstract The path of tokamak fusion and International thermonuclear experimental reactor (ITER) is maintaining high-performance plasma to produce sufficient fusion power. This effort is hindered by the transient energy burst arising from the instabil

Quantification of locked mode instability triggered by a change in confinement

Publikováno v: Nuclear Fusion, Vol 64, Iss 10, p 106029 (2024)

This work presents the first analysis of the disruptive locked mode (LM) triggered by the dynamics of a confinement change. It shows that, under certain conditions, the LM threshold during the transient is significantly lower than expected from stead
