Tokamak ignition equilibria and their stability are examined in a radially dependent model with empirical (Alcator) scaling for the energy confinement time. The empirical energy loss term corresponds to a diffusion operator, whose stationary eigenfunctions are the ignition equilibria. The dispersion relation for fluctuations around these equilibria is then(More)
2 ABSTRACT The existence of thermally stable sub-ignited equilibria of a tokamak reactor, sustained in operation by a feedback-controlled supplementary heating source, is demonstrated. The establishment of stability depends on a number of radially non-uniform, nonlinear processes whose effect is analyzed. One-dimensional (radial) stability analyses of model(More)
