The transmission anode micro X-ray tube is a key component of energy dispersive X-ray Fluorescence Analysis (EDXRFA) as exciting source. So in EDXRFA we hope to get the primary X-ray spectrum which is simply distributed. In the present paper, the authors used the Monte Carlo (MC) method to study the spectrum character of the transmission anode micro X-ray tube with different thickness of target. We cut the spectrum into high energy (5keV-50keV) part and low energy (< 5 keV) part and compared them to each other. The result showed that the flux of high energy part is big and the flux of low energy part is small when the electron energy is 50 keV and the target is 4 microm thick Ag. This is better for EDXRFA.
透射阳极微焦点X射线管作为能量色散X射线荧光分析（EDXRFA）的激发源是一个关键部件。因此在EDXRFA中，我们希望获得分布简单的一次X射线谱。在本文中，作者使用蒙特卡罗（MC）方法研究了不同靶厚度的透射阳极微焦点X射线管的能谱特性。我们将能谱分为高能（5keV - 50keV）部分和低能（<5keV）部分并进行比较。结果表明，当电子能量为50keV且靶为4微米厚的银时，高能部分的通量较大，低能部分的通量较小。这对EDXRFA更有利。
