Pinch Motion of a Cylindrical Plasma

The self-pinch motion of a cylindrical plasma is analyzed by using the two-fluid model of electrons and ions. The Lorentz force caused by currents flowing through the plasma along the cylindrical axis acts only on the electrons, because most part of the current is carried by the electrons. Thus the charges are separated and the electric field is induced in the radial direction. The ions are accelerated secondarily by this electric field. As the initial rate of increase of the currents increases and the plasma density decreases, the charge separation becomes greater. Depending on the magnitudes of these quantities the motions are classified into two types, namely the thorough charge separation and the plasma oscillation after the separation. Numerical examples show that the behaviors of the plasma are different from the result obtained by the one-fluid model.
