Summary on Grant Application Form
This highly original experimental programme has a simple strategy: the novel exploration of the magnetic liquid - edge plasma overlap. It embodies twin concepts: I. Simulating experimentally the behaviour of magnetofluid plasmas near magnetic or material boundaries by using ferrofluids; and II. Exploiting the mechanical coupling between ferrofluids and the external magnetic influences of (say) a real boundary plasma as a means of sensing and controlling unstable edge plasma behaviour. The programme under ( I ) will investigate the fundamental surface interface behaviour of a ferrofluid driven mechanically, and by externally applied magnetic fields, as a direct experimental analogy of the behaviour of magnetofluid 'skin' which is the plasma edge. The magnetic influence in the evolution of critically sheared flows and non-linear standing waves will be investigated, enabling an original detailed study of magnetofluid edge evolution, including splashing, wave-breaking and detached flows in X-point and other configurations. Strand (II) will determine directly the influence of typical plasma edge fields on ferrofluid deployed as a passive diagnostic, and as a viscous damping agent for plasma control.These imaginative applications promise great pains in inexpensive simulation, monitoring and passive control of edge plasmas, relevant to industrial and magnetic confinement processes.
