DOIAbstract
"A 20MW Lower Hybrid Current Drive system using an antenna based on the Passive-Active Multijunction. (PAM) concept is envisaged on ITER. This paper gives an overview of the mechanical analysis, modeling. and design carried out on two major elements of the antenna: the grill front face, and the RF feed-through. or windows. The front face will have to withstand high heat and fast neutrons fluxes directly from the. plasma. It will be actively cooled and present a beryllium coating upon ITER requirement. The RF window. being a critical safety importance class component (SIC) because of its tritium confinement function, two. of them will be put in series on each line to achieve a double barrier. A design of a water cooled 5GHz. CW RF “pillbox” ...
