This project aims to apply a static plasma modelling approach to linear modes of vibration and nonlinear explosive events in toroidally confined fusion plasma experiments and stellar atmospheres. The long-term survival of advanced civilisation depends on the development of reliable and ecologically sustainable energy sources. One of the most promising approaches for baseload electrical power is magnetic confinement fusion: harnessing, in a magnetic field, the nuclear reactions that power stars. This project will develop powerful new ways of modelling strong plasma instabilities in magnetised plasmas. Learning how to avoid these would remove a key barrier to fusion power.

该项目旨在将静态等离子体建模方法应用于环形约束聚变等离子体实验和恒星大气中的线性振动模式和非线性爆炸事件。先进文明的长期生存取决于可靠和生态可持续能源的发展。最有希望的基荷电力方法之一是磁约束聚变：在磁场中利用为恒星提供动力的核反应。该项目将开发强大的新方法来模拟磁化等离子体中的强等离子体不稳定性。学习如何避免这些问题将消除核聚变发电的一个关键障碍。
