Abstract

The aim of this research studying soft x-ray emission from United Nations University/International Centre for Theoretical Physics Plasma Fusion Facility (UNU/ICTP PFF) plasma focus device with nitrogen gas pressure changes and find the maximum value of soft x-ray yield by using the standard parameters of device and do optimization to obtain the combination of pressure and electrodes dimensions that gives the maximum value of soft x-ray yield. Many numerical experiments were carried out using Lee code and obtained the maximum value of soft x-ray yield 0.193J at pressure 1.9 Torr by using the standard parameters of device. We optimized the device and found the optimum combination of pressure and electrode dimensions (P0 = 0.5 Torr, z0 = 9 cm, a = 3.19 cm, b = 3.2 cm,) that gives the maximum value of soft x-ray yield Ysxr = 2.7 J without changing the energy of the device.
