论文摘要
我们使用低活性（1.8 $ \ times10^6 $ 〜dpm）\ nuc {99} {tc} $β$源来详细介绍可变能量，X射线荧光源的设计。通过在Ti，Zn，NB，Ag和Au的箔纸之间旋转源，该设备以接近1 Hz的速率产生X射线4至70 keV。当源位于存储位置时，外部辐射是不可检测的。屏蔽和旋转机制的设计允许在真空和液氮温度下使用。该设计旨在研究对GE检测器表面撞击辐射的低能量响应。该源将有助于理解大规模GE阵列中的检测器响应，例如\ textsc {majorana}和Legend。
We detail the design of a variable energy, x-ray fluorescence source using a low activity (1.8$\times10^6$~dpm) \nuc{99}{Tc} $β$ source that irradiates thin foils. By rotating the source among foils of Ti, Zn, Nb, Ag, and Au, the device produces x rays between 4 and 70 keV at a rate near 1 Hz. When the source is placed in a storage position, the external radiation is non-detectable. The design of the shielding and rotation mechanism permits use in vacuum and at liquid nitrogen temperature. The design is intended for the study of the low energy response to radiation impinging upon Ge detector surfaces. The source will be useful for understanding the detector response in large-scale Ge arrays such as \textsc{Majorana} and LEGEND.
