Detailed Fokker-Planck calculations of fusion rates from 160 keV 3He injection are presented, with and without combined RF/NBI heating. If technically possible, 3He injection at 160 keV has many advantages and can be used in JET as a heating method. Detailed experiments are proposed, including studies of fast ion and thermal distributions by fusion product and charge exchange diagnostics with separated beam and plasma components; ion temperatures in the 25-50 keV range; synergistic effects of combined NBI/RF; simulation of alpha-particle thermalisation and diffusion; sawteeth and instability phenomena and low neutron emission. These experiments offer the possibilities of both extending JET's operating parameters and increasing understanding of high ion temperature plasmas.
