论文摘要
商业阿尔法计数器用于科学和行业应用中,以筛选表面ra污染的材料。在本文中,我们表征了Xia Ultralo-1800,一个电离漂移α计数器,并研究了聚乙烯样品测量中对嵌入式电荷的响应。我们表明,在基于GEANT4的仿真框架并试图得出校正的情况下,对这种效果进行建模是可能的。本文还证明了使用抗静态风扇消除嵌入式电荷的有效性,并恢复了Alpha计数器中97.73%的Alpha检测效率。
Commercial alpha counters are used in science and industry applications to screen materials for surface radon progeny contamination. In this paper, we characterize an XIA UltraLo-1800, an ionization drift alpha counter, and study the response to embedded charge in polyethylene sample measurements. We show that modeling such effects is possible in a Geant4-based simulation framework and attempt to derive corrections. This paper also demonstrates the effectiveness of the use of an anti-static fan to eliminate the embedded charge and recover a 97.73% alpha detection efficiency in the alpha counter.
