Abstract
Strong shaping, favourable for stability and improved energy confineme nt, together with a significant expansion of the central region of imp roved confinement in negative central magnetic shear target plasmas, i ncreased the maximum fusion power produced in DIII-D by a factor of 3. Using deuterium plasmas, the highest fusion power gain, the ratio of fusion power to input power, Q, was 0.0015, corresponding to an equiva lent Q of 0.32 in a deuterium-tritium plasma, which is similar to valu es achieved in tokamaks of larger size and magnetic field. A simple tr ansformation relating Q to the stability parameters is presented.
