Abstract :
Summary form only given. While lower hybrid (LH) waves are very efficient in controlling the current profiles in the outer edges of a plasma, it is very difficult to design standard multijunction grills to launch waves in the 5-8 GHz range because of cooling and structural stability. However, if one turns to the quasi-optical grill (QOG), one can design microwave launchers that are relatively simple and robust. Applications are made to design of QOG for ITER-like plasmas as well as EBW for NSTX plasmas.
