摘要:

暗物质和中微子观测等稀有事件粒子物理实验要求探测器气体中的放射性杂质保持在极低水平。Zeolite是一类众所周知的材料,是从这些气体中去除杂质的候选材料之一。同时,吸附材料释放的放射性杂质量需足够小。本文报道了通过筛选超低放射性材料开发出的一种新型超低放射性Zeolite。此外,还描述了氩气中氡释放及杂质吸附的测量结果。

英文摘要:

The amount of radioactive impurities contaminated in the detector gases is required to be kept at a very low level for rare event particle physics such as dark matter and neutrino observation experiments. Zeolite is a well-known class of materials and is one of the possible candidates for removing impurities from these gases. At the same time, the amount of radioactive impurities released from the adsorbent material needs to be sufficiently small. In this paper, a development of a new ultralow radioactive zeolite as a product of the selection of ultralow radioactive materials is reported. Results on the radon emanation and impurity adsorption from argon gas measurements are also described.
