Effect of multijunction grill length on its lower hybrid current drive efficiency

  • Published:
Czechoslovak Journal of Physics Aims and scope

Abstract

The distance between the junction of subsidiary waveguides in the main waveguide and the grill mouth has an important influence upon the spectrum of radiated waves, the total reflection coefficient, the power distribution among the separate waveguides and the actual phases of incident waves. This effect is nearly as important as that of the phase shift between the adjacent waveguides and it is necessary to carry out optimization with respect to this parameter in the grill design.
