水切伦科夫探测器中钆的研究

Gadolinium study for a water Cherenkov detector

Atsuko Kibayashi

摘要:

本文提出了一种通过添加钆来改进大型水切伦科夫探测器的方法。Gd的大截面将大大提高对来自超新星和反应堆的反电子中微子的灵敏度。一个为期五年的项目,建立和开发一个原型探测器的基础上超级神冈(SK)已经开始。我们正在进行各种研究,包括Gd溶液中的材料浸泡测试,光衰减长度测量,净化系统开发以及使用SK数据和基于Geant 4的模拟进行中子标记效率测量。我们介绍了该项目的概况和最近的研发成果。

英文摘要:

Modification of large water Cherenkov detectors by addition of gadolinium has been proposed. The large cross section for neutron capture on Gd will greatly improve the sensitivity to antielectron neutrinos from supernovae and reactors. A five-year project to build and develop a prototype detector based on Super-Kamiokande (SK) has started. We are performing various studies, including a material soak test in Gd solution, light attenuation length measurements, purification system development, and neutron tagging efficiency measurements using SK data and a Geant4-based simulation. We present an overview of the project and the recent R&D results.
