Abstract Text:
In this work, we explore the fundamental question of whether finite-beta plasma states, including those predicted by 3D equilibrium codes, can be reached in practice. To do so, we use the extended-MHD code, M3D-C1, to study the effect of applied heat sources on the self-consistent evolution of non-axisymmetric, finite-beta equilibria. Under realistic, anisotropic heat transport conditions, we investigate the confinement properties of the dynamically accessible states. Under appropriate heating conditions, we observe cyclic, sawtooth-like behaviour, which is consistent with what has been observed experimentally on machines such as the Large Helical Device. Equilibrium codes form the bedrock of modern stellarator optimisation, which makes it crucial to understand the conditions under which the states predicted by these tools can be reached in practice.
