Cs2 LiYCl6∶ Ce 晶体的 n / γ 双探测闪烁性能研究.

Cs2 LiYCl6∶ Ce(CLYC) is a novel scintillation crystal with the capability of neutron and gamma-ray detection. It can be used in the field of neutron and gamma-ray detection. The CLYC scintillation crystal with 95% enrichment of 6 Li was grown by the vertical Bridgman method. After processing and moisture-proof packaging, a housed sample of ϕ50 mm ×50 mm CLYC scintillation crystal was obtained. 4. 22% energy resolution is measured at 662 keV of 137Cs gamma rays. Neutron-gamma discrimination is also achieved. The figure of merit (FOM) of pulse shape discrimination (PSD) measured with a 252Cf neutron source is 3. 45. With its excellent performance, CLYC scintillation crystal is expected to replacement for Helium-3 gas in the field of neutron detection, and can be used as the preferred material for n/ γ dual detection. So CLYC crystal can be used in neutron radiation detectors, radioisotope identification instruments, personal radiation dosimeters, and other neutrons gamma detection. [ABSTRACT FROM AUTHOR]
