Abstract

A complete magnetic data analysis in tokamaks should comprehend a reconstruction of the axisymmetric magnetic flux structure and information on location, width and rotation of relevant island structures produced by resistive tearing modes. A computerized procedure is desirable, especially in conditions of non-circular plasma and vessel cross sections. Outside an island centered around the q = m/n surface the true nonlinear solution of the tearing mode equation is well approximated by the linear eigenfunction characterized by the logarithmic slope jump "TRIANGLE"'(O); also the quasilinear saturated width of the island is usually calculated by exploring the linear solution around the resonance until "TRIANGLE"'(w) = O.
