Magnetised Complex Plasmas
Technological Plasmas Group Page
An improved understanding of the transport and fate of dust in the next generation of tokamak plasmas is of particular concern since dust can reduce the performance and efficiency of the reactor and generate radioactive contaminants. The aim of this project is to experimentally study dusty plasma phenomena in magnetised plasmas, focusing on collective effects such as crystal formation and wave propagation as well as solitary dust transport. Experimental results will be compared with computer simulations of dust particle transport in stable and turbulent magnetised plasmas to improve them. This project is in collaboration with the University of York, Imperial College London and the DIFFER institute (Netherlands). The experimental work involves the use of laser based dust diagnostics, Langmuir probes and filtered optical imaging .
