在以氢气放电源打钆靶为例,分析氢气放电源打靶谱时,发现有以下几类谱线:源谱、靶材料的特征X射线、衍射谱线和一些未知谱线。根据打靶的初级谱可以分辨出源谱;根据靶材料的成分可将特征线区分出来;用改变靶面和入射角、固定测量角的方法及打多晶体靶和非晶体靶的方法可以分辨出X射线衍射谱线;剩下的无法辨识的那些谱线是一种未知谱线,对它的认识还在深入中。
In the case of a hydrogen discharge source, a gadolinium target is taken as an example. When analyzing the target spectrum of the hydrogen discharge source, the following types of spectra are found: the source spectrum, the characteristic X-ray of the target material, the diffraction spectrum and some unknown spectra. According to the primary spectrum of the target, the source spectrum can be distinguished; the characteristic lines can be distinguished according to the composition of the target material; the method of changing the target surface and the incident angle, the method of fixing the measurement angle and the method of multiplicating the target and the target can be distinguished X-ray diffraction line; the remaining unrecognized line is an unknown line, its understanding is still in-depth.
