| Abstract | Abstract: The action of the driven electric field upon trapped particles in toroidal devices of tokamak ordering and the possible modification that this may cause on the neoclassical resistivity are investigated in this paper. The toroidal electric field accelerates the parallel component of trapped particles velocity reducing their pitch angle such that they become untrapped. According to the usual neoclassical theory, the trapped particle fraction goes to zero in the magnetic axis as , leading to an undesirable singular behaviour of the current density profile in this region. The objective of this paper is to analyse the overall effect of particle detrapping due to the presence of the toroidal electric field over the whole plasma cross section and in which extension this detrapping may eliminate the “catastrophe” of infinite current density gradient at the magnetic axis. A convolution between the electric field and collisionality effects is developed in order to illustrate the modified profile of the current density in the region near the magnetic axis of a typical tokamak. |
