Improving our understanding of turbulence is hard, due to (1) the complexity of fusion-grade plasmas (the presence of ionised particles and magnetic fields make this into a much harder topic than fluid turbulence), (2) the enormous variety of plasma instabilities, and (3) the difficulty of diagnosing the plasma due to the hostile conditions inside the plasma. | Improving our understanding of turbulence is hard, due to (1) the complexity of fusion-grade plasmas (the presence of ionised particles and magnetic fields make this into a much harder topic than fluid turbulence), (2) the enormous variety of plasma instabilities, and (3) the difficulty of diagnosing the plasma due to the hostile conditions inside the plasma. | ||
Our work on turbulence has focussed mainly on the analysis of edge probe data, although some analysis was done on other types of data (e.g., reflectometry signals). A large effort was devoted to the development of new analysis techniques. | Our work on turbulence has focussed mainly on the analysis of edge Langmuir probe data, although some analysis was done on other types of data (e.g., reflectometry signals).
