Some Results of Plasma Focus Studies

  • V. M. Korzhavin

Abstract

The “Plasma Focus ” is a dense (n = 1019 cm -3), high temperature (T ~ 103 to 104 eV) plasma column, which is about 1 cm long and about 0.1 to 1 cm in diameter. It is formed on the axis of the discharge chamber as a result of a cumulation of the non-cylindrical plasma sheath accelerated by the magnetic pressure of the discharge current. The most advantageous features of the Plasma Focus devices are a high neutron yield for a rather small energy supply and a very simple machine design. A neutron yield of the order of 1012 neutrons per discharge is produced for a 300 to 400 kJ energy supply. The Plasma Focus is also a very intense source of X-rays with an energy of some hundred keV which is that of high current deuteron beams.
