摘要
A consistent picture of sawteeth-induced impurity transport is presented based on a recently given model for plasma redistribution by sawtooth crashes. The redistribution model is based on ideal magnetohydrodynamic conservation laws and assumes that the magnetic flux and the volume of the layers that reconnect during the crash are conserved. The post-crash redistributed impurity density is found in terms of the impurity density before the crash and the profiles of the safety factor before and after the crash. Comparisons with experimental results show good qualitative agreement. (C) 1996 American Institute of Physics.
