Abstract

A nonlinear ideal magnetohydrodynamic (MHD) theory of explosive flux tube eruptions in a tokamak was developed. The theory predicted that the ballooning instability ejected a flux tube of hot plasma into the colder edge plasma region. The flux tubes confined in tokamaks were found to erupt explosively and similar eruptions occurred in astrophysical plasmas. It was observed that the flux tubes rise explosively, narrow and twist to pass through overlying magnetic field lines without reconnection.
