Abstract	A conceptual design of a new tokamak has been elaborated by the Fusion Department of ENEA (Frascati, Italy). The machine, so far called FT-3, aims to study burning plasmas and to prepare ITER scenarios thus hoping to be approved to be part of the accompanying program. FT-3 could start operations by the end of the ITER construction. It will be able of high plasma performance in a dimensionless parameter range close to that of ITER with pulse length long enough to address steady state physics. FT-3 will work with Deuterium plasmas and will simulate the alpha particle dynamics by using fast ions accelerated by powerful heating and current drive systems. Main heating source will be an Ion cyclotron radio frequency (ICRF) system that, in its initial configuration, will couple to the plasma 20 MW (extendible to 30 MW) at 60-90 MHz. To address Advanced Scenarios and steady state physics at high plasma density $(n_{e}$ ges $10^{20}$ $m^{-3}$ ) it is foreseen the installation of a lower hybrid (LH) system to control the current profile via off axis current drive (CD). A minimum coupled power of 6 MW is considered necessary to achieve the expected scenarios. The LH launching structure is based on the PAM concept, which coupling properties have been recently demonstrated on the Frascati Tokamak Upgrade (FTU). A conceptual analysis of the two systems is given.
