Microinstabilities, Turbulent Transport, and Structure Formation in Helical Plasmas

In this paper, microturbulence, turbulent transport, and related structure formation mechanisms in helical plasmas are discussed, with special attention to application to Large Helical Device (LHD) plasmas. The research frontier for the physics of anomalous transport and confinement improvement is illuminated, and future direction of the confinement research is illustrated.
