摘要

Purpose

Glass is a potential choice for the scintillator in Hadronic calorimetry (HCAL) of the CEPC. It requires sophisticated instruments and suitable methods to obtain scintillation properties of the glasses in the first time. It is necessary to establish an evaluation method for nuclear radiation detection performance of glass scintillator.

Methods

The spectroscopy research of the glass includes transmission/absorption spectrum and emission spectrum. The time characteristics include rise time, scintillation decay time and afterglow. The scintillation properties include light yield, energy resolution and minimum ionizing particle (MIP) response. And a new method for measuring the low light yield of glass scintillators is proposed.

Results

We have built a complete performance test system and evaluation method, which can evaluate the nuclear radiation detection performance of different glass scintillators.

Conclusion

By continuously improving the composition and preparation process of the glass, it can provide potential possibilities for the application in the high-energy physics experiment and nuclear radiation detection fields.
