Controlled thermonuclear fusion power apparatus and method

A method is claimed of obtaining energy from fusible plasma in a toroidal magnetically confined fusion power core. A deuterium and tritium mixture is introduced into a toroidal region to generate a low density plasma. The plasma is ohmically heated until temperatures reach approximately 4 - 6 KeV and alpha-particle heating from D,T fusion reactions balances bremsstrahlung losses. Additional fusion fuel is introduced into the toroidal regions to raise the density of the plasma. Heating of the plasma is continued ohmically and from alpha-particle heating in excess of bremsstrahlung losses so that a temperature of at least 4 - 6 KeV is reached and alpha-particle heating balances bremsstrahlung and cyclotron radiation losses and particle conductivity losses. Still additional fuel is introduced to raise the plasma temperature and density. Energy from the fusion reactions is absorbed by a fluid and converted into electrical and/or mechanical energy
