论文摘要
粒子探测器对不同类型的辐射的响应不一定是相同的，在某些情况下，忽略了这种行为会导致对获得的数据的误解。尽管商业放射性来源通常适合调查对$β$和$γ$的响应，但在$α$的情况下，对定制来源的需求是源于$α$辐射的固有性能，这强加了发射器直接面对检测器。在这项工作中，我们展示了如何灵活地产生$α$源，以用于多个检测器表征研究。这些是从从Cern的Isolde设施的放射性$^{228} $ ra ions收集的一组主要来源获得的。我们说明了该技术的潜力，该技术的实用案例可用于闪烁器和降压器检测器，以及迄今为止获得的结果的示例。
The response of particle detectors to different types of radiation is not necessarily identical and, in some cases, neglecting this behavior can lead to a misinterpretation of the acquired data. While commercial radioactive sources are in general suitable to investigate the response to $β$'s and $γ$'s, in the case of $α$'s the need for custom-made sources arises from the intrinsic properties of $α$ radiation, which imposes that the emitter directly faces the detector. In this work, we show how to flexibly produce $α$ sources to be employed in multiple studies of detector characterization. These are obtained starting from a set of primary sources obtained from the collection of radioactive $^{228}$Ra ions at the ISOLDE facility at CERN. We illustrate the potential of this technique with practical cases of application to scintillators and bolometric detectors and examples of the results obtained so far.
