Abstract

A knowledge of the properties of the plasma boundary layer and their changes during the application of RF power is of general interest. Measurements of electron temperature and density are needed to understand the behaviour of impurities in the edge region. Radial profiles of electron density determine, in addition to other parameters, the coupling resistance of the ICRH antennae. The energy flux is needed for designing the limiters which are shaped to homogenize the radially dependent heat load. A very important parameter for the proper design of a limiter is the e-folding length for the energy flux. The total flux is also needed to understand the confinement of particles and energy during ICRH heating and from the density profile the diffusion coefficient D-perpendicular in the boundary may be estimated.
