论文摘要
笔是一种工业聚酯塑料，对于物理界来说，它是一种新型的塑料闪烁体。笔在蓝色政权中闪闪发光，这是大多数光发射器设备的理想选择。此外，笔具有出色的机械性能，并且已经达到了非常好的放射性功能。因此，它是低背景实验中主动结构成分的理想候选者。一种可能的应用是在低温液体中运行的锗探测器的持有者（Lar，LN2）。这样的结构可以帮助拒绝表面和外部背景，从而提高实验的灵敏度。在这项贡献中，概述了笔上的r \＆d，并报告了对传奇-200实验的首次生产的钢笔结构的评估。
PEN is an industrial polyester plastic which has become interesting for the physics community as a new type of plastic scintillator. PEN scintillates in the blue regime, which is ideal for most photosensor devices. In addition, PEN has excellent mechanical properties and very good radiopurity has been achieved. Thus, it is an ideal candidate for active structural components in low-background experiments. One possible application are holders for germanium detectors operating in cryogenic liquids (LAr, LN2). Such structures can help to reject surface and external backgrounds, boosting the sensitivity of experiments. In this contribution, the R\&D on PEN is outlined and an evaluation of the first production of PEN structures for the LEGEND-200 experiment is reported.
