Numerical simulation of spherical plasma focus device using Lee model

Summary form only given. The plasma focus device is a potential source for multi-radiation emission. Lee model has been developed with a complete description of the plasma focus dynamics to simulate the plasma motion in both the axial and radial phase. The code couples the electrical circuit with plasma focus (PF) dynamics, thermodynamics and radiation. Spherical plasma focus device is a special case between Mather and Filippov configurations. Spherical electrodes made the chamber design more compact when compare to Mather-type and Filippov-type. In this study, numerical simulation for spherical plasma focus device using Lee model has been performed to test the universality of Lee model. Experimental results from a spherical plasma focus device is compared with numerical simulations results in terms of neutron yield and X-ray radiation for different gases and at different pressure.
