论文摘要
在这项工作中，我们为模块化tritium tritium water实时监视器提供了仿真结果。该系统允许可扩展性以达到所需的灵敏度。这些模块由浸入水中的340个无闪烁的闪烁纤维和2个光电传感器组成。讨论了低能量β颗粒的光产量和Birks的系数不确定性。提出了根据纤维长度对检测效率的研究。介绍了有关符合欧洲指令2013/51/euratom所需的灵敏度的系统要求和背景缓解的讨论。由于Tritium的能量β发射较低，因此计算了一个接近3.3 \％的检测效率。
In this work we present simulation results for a modular tritium in-water real-time monitor. The system allows for scalability in order to achieve the required sensitivity. The modules are composed by 340 uncladed scintillating fibers immersed in water and 2 photosensors for light readout. Light yield and Birks' coefficient uncertainties for low energy beta particles is discussed. A study of the detection efficiency according to the fiber length is presented. Discussion on the system requirements and background mitigation for a device with sensitivity of 100\,Bq/L, required to comply with the European directive 2013/51/Euratom, is presented. Due to the low energetic beta emission from tritium a detection efficiency close to 3.3\% was calculated for a single 2\,mm round fiber.
