用于超低放射性测量的BiPo探测器
The BiPo detector for ultralow radioactivity measurements
摘要：
BiPo项目致力于测量SuperNEMO源箔的极低放射性污染（^{208}Tl < 2 \muBq /kg和^{214}Bi < 10 \muBq /kg）。研发阶段已经开始：一个模块化的BiPo原型及其屏蔽测试设施正在建设中。该原型的目的是研究背景，特别是表面污染的净化器。第一个胶囊已于10月17日安装在Canfranc地下实验室，现在正在收集数据。经过10.7天的测量，初步确定了样品表面放射性纯度的上限为A（^{208}Tl）< 60 \muBq /m^2（90%C. L.）的范围内。已经获得。
英文摘要：
The BiPo project is dedicated to the measurement of extremely low radioactivity contamination of SuperNEMO source foils (^{208}Tl < 2 \muBq/kg and ^{214}Bi < 10 \muBq/kg). The R&D phase is started: a modular BiPo prototype with its shielding test facility is under construction. The goal of this prototype is to study the background and particularly the surface contamination of scintillators. The first capsule has been installed in the Canfranc Underground Laboratory in October, 17th and is now taking data. After 10.7 days of measurements, a preliminary upper limit on the surface radiopurity of the scintillators of A(^{208}Tl) < 60 \muBq/m^2 (90% C. L.) has been obtained.
