Status of and prospects for Advanced Tokamak regimes from multi-machine comparisons
To date, the international ITB database has been mainly used to study the ITB formation conditions (prelude phase). In this paper, an assessment is given of the present fusion performance of the advanced tokamak regimes for non-inductive operation (high performance phase of the scenario). The operational domain of AT regimes is mapped in terms of performance but also in terms of dimensionless plasma physics quantities such as normalised Larmor radius, collisionality, Mach Number and ratio of ion to electron temperature. The gap between present day and future advanced tokamak experiments is quantified. Finally, an attempt is made to identify the required experimental effort to reduce the uncertainties when extrapolating non-inductive regimes to next step experiments.
