Current outflow to low-density plasma region of z-pinch with pre-embedded axial magnetic field

摘要

1.INTRODUCTION Magnetic flux compression can be achieved within a conducting shell when the shell is collapsed by the application of an external force. In z-pinch scheme, the conductor is plasma that implodes by the J×B force due to a large current flowing through it. The subject of magnetic field compression by imploding plasma has gained particular interest due to the advances in producing plasmas of high temperature and density for fusion purposes, based on the approach of magnetized plasma compression [1].
