Abstract

Under certain modes of operation of very large tokamaks such as the proposed two-component torus (TCT), it is possible to create oppositely directed density and temperature gradients (nT<0) in the hotter central region of the plasma and the usual profile (nT>0) on the colder outer edge. Such configurations are found to be very favorable to stability against trapped-particle modes.
