Description

The lower hybrid current drive experiment on JET, aimed at generating current in the plasma by launching a wave at 3.7 GHz into the torus, required the building of a large high power microwave generator and antenna. The generator can provide 15 MW for 10 seconds or 12 MW for 20 seconds. This power will be fed to a phased-array antenna consisting of 48 stainless steel modules assembled in an array of 384 waveguides. The antenna position will be controlled in real time in order to optimize the coupling to the plasma. The phasing between different modules can be set so as to vary the N// between 1.8 and 2.4. 4 refs., 5 figs., 1 tab
