摘要
大型水切伦科夫(WC)探测器既用于质子衰变搜寻也用于中微子物理,已成为粒子物理中非常成功的工具。它们以质量大和带电粒子探测能力强而著称。虽然目前的 WC 探测器能在很宽的能量范围内重建带电粒子径迹,但它们无法高效探测中子。钆(Gd)在所有稳定核中具有最大的热中子俘获截面,并产生可被高效探测的 8 MeV 伽马级联。由于在溶解了钆盐的水中通过中子标记可开辟许多新的物理机会,为此建立了一个名为 EGADS 的大规模研发计划,以论证该技术的可行性。EGADS 具备 WC 探测器的所有组件,主要是一个装有 240 个光电探测器、数据采集系统(DAQ)以及能在保持钆处于溶液状态的同时去除水中所有杂质的水处理系统的 200 吨不锈钢水箱。本文中我们讨论了论证这一新技术可行性所达成的里程碑,并详细介绍了 EGADS 的特性。
