Power deposition profiles during lower hybrid heating of Tokamak plasmas
Description
A ray-tracing numerical code has been adapted to evaluate the power deposition profiles during Lower Hybrid heating of Tokamak plasmas. In the first part of this report we briefly introduce the physical model of LH heating which is used, and the equations solved by the code. We then describe the approximations which allow a rapid evaluation of the absorption by ions and by electrons as a function of radius, from the results of the ray-tracing subroutine. These profiles are ready for use as heat sources in a radial transport-code simulating the Tokamak discharge. Finally, we present a set of examples relevant for the LH heating experiment planned on the ASDEX Tokamak. (orig.)
