Transport and plasma control in the Tj-Ii stellarator
This paper shows the effect of 3D geometry on transport and plasma control in the TJ-II stellarator. The fuelling and impurity transport are affected due to the enhancement of neoclassical (NC) transport and subsequent onset of a radial electric field. Turbulence affects not only plasma but also n...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | This paper shows the effect of 3D geometry on transport and plasma control in the TJ-II stellarator. The fuelling
and impurity transport are affected due to the enhancement of neoclassical (NC) transport and subsequent onset of a
radial electric field. Turbulence affects not only plasma but also neutral density, with effects on the fuelling. SOL is
shown to be affected by plasma edge turbulence. The properties of stability and MHD modes are also explored. The
plasma flow is shown to be affected by 3/2 magnetic island. Promissing experimental results show the possibility of
controlling Alfvén modes by ECRH, and magnetic configuration by rotational transform and magnetic well scans. |
