JET Passive Active Multijunction Lower Hybrid Launcher
Lower hybrid power in the range of 5MW will be needed to maintain the required current profile in Advanced Tokamak discharges in JET at ITER relevant beta and rho*. To couple reliability this power in discharges with Elmy edge, a passive active multijuction (PAM) has been designed. A PAM experiment on JET would also allow testing this type of launcher in operative scenarios as close as possible today to ITER coupling conditions. A preliminary coupler design has been completed. Firstly the physic rationale for the choice of the antenna parameters will be presented then an overall description of the antenna with the results on coupling studies will be given.
