Neon Soft X-Ray Yield Optimization from NX2 Dense Plasma Focus Device

The aim of this research is to study soft x-ray emission from nx2 plasma focus device with neon filling gas using the lee model code and find the maximum value of soft x-ray yield by using the standard parameters of the device and then find the optimum combination of pressure and anode dimensions that gives the maximum value of soft x-ray yield. many numerical experiments were carried out and we obtained the maximum value of soft x-ray yield (ysxr) of (22.6 j) at a pressure of (2.9 torr) by using the standard parameters of nx2 device. we found the optimum combination of pressure, anode length and anode radius (3 torr, 2.1 cm and 2 cm), respectively, by reducing the anode length and increasing the anode radius. the soft x-ray yield increases to (26.01 j) with a corresponding efficiency of about 1.53%.
