【摘要】 在预作X光激光增益介质的中Z靶(象锗靶)中均匀掺人少量的低Z元素(象铝),利用后者的类氦谱线强度比确定了等离子体状态;同时还在PLTE近似下由锗线的强度比确定了等离子体状态,二者基本吻合。更多还原

【Abstract】 A small amount of low Z element (AI) was mixed into a middle Z(Ge) target (Ge plasma was used as an X-ray laser gain medium) .Using the line intensity ratio of He-like Al ions, the plasma electron density and temperature were determined. Meanwhile, the plasma characteristic was also determined by the line intensity ratio of Ge ions in PLTE model. Both of them are consistent.更多还原
