Often used standard light source is synchrotron radiation source and wall stabilized argon arc source 常用的光源标准如同步辐射光源和壁稳亚弧光源等。
Synchrotron radiation source ' s excellent characteristic made it as ideal euv and soft x - ray standard source , the spectrum can be calculated from the storage ring parameters 同步辐射的一系列优异的特性决定了它是非常理想的极紫外和软x射线标准光源,辐射光谱可以通过存储环的参数计算得到。
