Abstract

Simulation of sawtooth dynamics with a 1-D transport code is proposed as a useful tool for the study of sawtooth models. A sawtooth model, based on enhanced radial transport as a mechanism for the internal disruption, is discussed. This transport is triggered, when a resistively growing m = 1 island exceeds its critical size, which depends on the local shear. Simulations of TFR and T-10 discharges show good agreement with experimentally observed sawteeth in Ohmically and electron cyclotron wave heated plasmas.
