Description

A 500 kW-30 ms-3.7 GHz L.H. experiment has been operated on Petula in order to test the physical and technical options taken for the Lower Hybrid system of TORE SUPRA. The antenna used to launch the wave to the plasma is a modular 18-waveguide grill using mainly the multijunction effect. This provides a great simplification of the antenna, but the 6 waveguides of a module are tightly RF coupled. This paper presents the RF behaviour of such an antenna: self-matching properties of the multijunction, plasma R.F. wave coupling. These studies have been supported by scrape-off layer density measurements before and during the RF pulses
