论文摘要
丙烯酸是一种流行的结构材料，在需要较低背景的实验中，由于其无线电性，可加工性和机械强度。但是，它的孔隙率可能会导致大量的气体吸收并长期影响检测器稳定性。丙烯酸与其他检测器材料之间的相互作用成为检测器设计中的关键问题之一。在本文中，我们进行了一个实验，以定量测量高压氙气的吸收过程中。为测量设计了特定的设置，并进行系统的测量以获得吸收量的结果：0.98 g氙气到332 g丙烯酸。
Acrylic is a popular structural material in experiments requiring low background because of its radio-purity, machinability, and mechanical strength. However, its porosity may cause significant gas absorption and influence the detector stability in the long term. The interaction between acrylic and other detector materials becomes one of the key concerns in the detector design. In this paper, we carry out an experiment to measure quantitatively the absorption process of high-pressure xenon gas into acrylic. A specific setup is designed for the measurement, and systematic measurements are done to obtain a result of the absorption amount: 0.98 g xenon into 332 g of acrylic.
