 note = {Magnetic island formation in three-dimensional finite-beta equilibria in the H-1 Heliac is studied by using the HINT code.  It is found that the size of a dangerous island should increase with beta but that a destruction of the equilibrium at low beta is avoided because the rotational transform evolves to exclude the rational surface concerned.  At higher beta there is evidence of near-resonant flux surface deformations which may lead to an equilibrium limit.  A reconnected equilibrium at still higher beta exhibits a double island structure which is similar to homoclinic phase portraits which have been observed after separatrix reconnection in Hamiltonian systems. Physical mechanism of the island formation in finite-beta helical equilibria is investigated to confirm there are cases where the global effect of the Pfirsch-Schluter currents is important.  The earlier theory is extended to elucidate the occurrence of the complete self-healing of island when the resistive interchange criterion satisfied.},
