Abstract:
The dependence of the core confinement on the edge plasma parameter is discussed in L-mode tokamaks. Employing the result of the transport analysis in the scrape-off layer, the boundary condition for the transport in the core plasma is expressed in terms of the heating power. Various forms of the dependences of the local thermal conductivity on the temperature and temperature gradient are examined. The power dependence of the edge temperature is found to be an origin of that the profile resiliency holds in a wide range of the heating power in L-mode tokamaks.
