Abstract

In 2021, the Institute of High Energy Physics proposed a design of glass scintillator coupled with SiPM as a new solution for the next generation calorimeter, to explore the application of glass scintillators in high energy physics and nuclear radiation detection. The Large Area Glass Scintillator Collaboration Group was established to research and develop a glass scintillator with high density, high light yields and fast decay time. Through continuous optimization, the glasses have excellent scintillation performance with a light yield of 1000 ph/MeV and a density of 6 g/cm3. Moreover, the neutron response of the glasses was investigated, and different high-energy particles can be distinguished by signal amplitude. In addition, the radiation resistance of different glasses was tested under proton beam. All the glasses appeared opaque and produced a high radioactive background, because Gd element interacts with proton to produce radionuclides with high activity and long half-life.

研发用于核辐射探测的玻璃闪烁体

2021年，高能物理研究所提出了一种与SiPM耦合的玻璃闪烁体设计方案，作为下一代量热计的新解决方案，探索玻璃闪烁体在高能物理和核辐射探测中的应用。成立大面积玻璃闪烁体协进组，研究开发高密度、高产光率、快衰减时间的玻璃闪烁体。通过不断优化，该玻璃具有优异的闪烁性能，出光率可达1000 ph/MeV，密度可达6 g/cm3。此外，研究了玻璃的中子响应，通过信号幅值可以区分出不同的高能粒子。此外，还测试了不同玻璃在质子束作用下的抗辐射性能。由于Gd元素与质子相互作用产生高活性、长半衰期的放射性核素，所有玻璃都呈现不透明，并产生高放射性本底。
