Bremsstrahlung spectrum data for thick targets by keV electrons

The dataset presented here is supplemental material for our paper published in Nuclear Instruments and Methods in Physics Research B 267 (2009) 3495-3499 (Lixia Tian, et al), entitled “Bremsstrahlung spectra produced by kilovolt electron impact on thick targets”. Experimental details have been given in this paper. The dataset includes our measured bremsstrahlung spectra on Al, Ti, Zr, Mo, and W thick targets for 5, 10, 15, 20, and 25 keV electron impact. Please notice that the experimental bremsstrahlung spectra in this dataset are multiplied by some factors (i.e., 3, 10, 30, 100 for 10, 15, 20, and 25 keV, respectively ) except for the case of 5 keV incident electron energy. The X-ray detector used in our experiment was an Ortec Si(Li) detector which was in vacuum, some detector parameters provided by the manufacturer were given in Tian et al's NIMB paper, and the detector active diameter was 4 mm. In our experiment, we made use of standard point sources to calibrate the detection efficiency of this X-ray detector (i.e., figure 1 in Tian et al's NIMB paper). Based on the figure 1 in Tian et al's NIMB paper, we can deduce the solid angle subtended by the detector, it was 0.003351, therefore we can estimate that the distance from the detector to the target was about 6.124 cm. These information may be useful for Monte Carlo simulations.

本数据集为发表于《Nuclear Instruments and Methods in Physics Research B》2009年第267卷第3495-3499页（作者田丽霞等）的论文《Bremsstrahlung spectra produced by kilovolt electron impact on thick targets》的补充材料，实验细节已在该论文中完整说明。本数据集涵盖了针对铝（Al）、钛（Ti）、锆（Zr）、钼（Mo）及钨（W）厚靶，在5、10、15、20与25 keV电子轰击下测得的轫致辐射（Bremsstrahlung）能谱。需注意，本数据集内的实验轫致辐射能谱，除5 keV入射电子能量的情况外，均已乘以相应的修正因子：10 keV、15 keV、20 keV及25 keV分别对应因子3、10、30、100。本实验所用的X射线探测器为置于真空环境中的Ortec Si(Li)探测器（Si(Li) detector），生产商提供的部分探测器参数已见于前述田丽霞等的NIMB论文，该探测器的有效直径为4 mm。实验过程中，我们采用标准点源对该X射线探测器的探测效率进行了校准（对应田丽霞等上述NIMB论文中的图1）。根据该论文中的图1，可推导出探测器所张的立体角为0.003351，由此可估算出探测器与靶材之间的距离约为6.124 cm。上述信息可用于蒙特卡洛（Monte Carlo）模拟研究。
