摘要
本研究的目的是研究联合国大学/国际理论物理中心等离子体聚变设施(UNU/ICTP PFF)等离子体聚焦装置在氮气压力变化下的软x射线发射，利用该装置的标准参数，找出软x射线产率的最大值，并进行优化，得到软x射线产率最大值的压力和电极尺寸组合。利用Lee码进行了多次数值实验，利用器件的标准参数得到了1.9 Torr压力下软x射线产率的最大值0.193J。我们对器件进行了优化，找到了最优的压力和电极尺寸组合(P0 = 0.5 Torr, z0 = 9 cm, a = 3.19 cm, b = 3.2 cm)，在不改变器件能量的情况下，软x射线产率最大值Ysxr = 2.7 J。
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.
