EVALUATION OF PLASMA PARAMETERS AND EXPERIMENTS ON THE PLASMA FOCUS

In this article, the problem of calculation of plasma parameters during the operation of the installation in the mode of Plasma Focus and setting an experiment on the replacement of coaxial cylindrical electrodes on the geometry of the plasma focus is posed. The fundamental parameters of the focus are calculated and the results of preliminary assessment of the plasma focus formation conditions are shown. The maximum value of temperature and electron concentration is determined by the formulas of the electrodynamic model. Calculations using the electrodynamic model show the dependence of the electron concentration on the anode radius. It is also found that an increase in the electron temperature is affected by an increase in the current, but the pulse time decreases. The obtained data allow to determine the values of the electron temperature if you change the radius of the anode from 0.25 cm to 2.25 cm, it is Shown that when the discharge current in the range kiloampere expected measurable neutron output, as well as sufficiently high values of temperature and density characteristic of hot plasma. The dependence of the discharge current on the voltage is shown. The experiments have shown that the dynamic parameters of the plasma, if not to take measures to significantly reduce the inductance of the system, are insufficient for strong pinch compression.
