Identification of the magnetic island structure in the HL-2A tokamak

doi:10.1088/1674-1056/20/9/095205

Abstract The identification of the magnetic island structure in the HL-2A tokamak is presented. First, the perturbation current as a source for the perturbation flux can be determined by using Mirnov probe measurements. By superposing the perturbation flux and the equilibrium flux reconnected by equilibrium fitting, the structure and the width of the magnetic islands can be estimated. The method has been used in the HL-2A experiments.

Keywords: magnetic island magnetohydrodynamic instability tearing mode
