Fusion Energy and the Physics of Burning Plasmas

With the construction of ITER, magnetic confinement fusion power enters the unexplored burning plasma regime, in which the collisional slowing of fusion product alphas dominates the heating process. As these alphas slow they can drive electromagnetic resonances, whose collective effects can eject the same alphas from confinement, damage the first wall, and if unchecked, prevent ignition. My research will resolve the physics of wave-particle-plasma nonlinear interactions, needed for understanding and reactor control. By driving Australian engagement with ITER, this project will also foster growth of Australian fusion science, thereby creating opportunities for Australian industry and helping to train a new generation of fusion scientists.
