Abstract:
In this report we build on existing theories of Edge Localised Modes (ELMs) that incorporate the theory of Magnetic Relaxation, firstly by introducing the effects of the bootstrap current and secondly by applying the relaxation model to the field of ELM mitigation. The bootstrap current is a toroidal plasma current that arises spontaneously as a result of the confinement of the plasma. It is shown that the effect of introducing this current is to split the ELM widths associated with this model into two classes; one group with large ELM widths, the other with small ELM widths. An analytical study is then carried out which provides a theoretical basis for this bifurcation of results. Finally the idea of ELM mitigation using Resonant Magnetic Perturbations will be introduced before the Relaxation Theory of ELMs is used to give new insight into ELM mitigation results.
