Abstract

A three-dimensional, nonlinear, numerical simulation is described in which saw-tooth oscillations occur as a result of a hydromagnetic relaxation instability. The time evolution of the magnetic topology demonstrates the essential validity of the model suggested by Kadomtsev to explain the saw-tooth oscillations observed in tokamak experiments.
