York Plasma InstituteWhy dont we have a single fusion reactor as yet?Why? Why? Why? Why? Transport ProcessesMicroinstabilities are the main derives of turbulent transport. Due to gradient in plasma profiles, temperature and density for exampleThey are characterised by: >> ~ i They elongate parallel to the magnetic field lines with relatively very short wavelengths perpendicular to it. > ~ i They elongate parallel to the magnetic field lines with relatively very short wavelengths perpendicular to it.
