The response of the recently developed Tl2LiYCl6(Ce) scintillator to neutrons was measured and the 35Cl(n,p) channel observed in the material for the first time. The scintillator was exposed to a 252Cf source mounted within a parallel-plate avalanche counter for fission-fragment coincident measurements. Proton- and t+α-like events are selected with the pulse-shape discrimination technique. Comparison of energy-deposition and time-of-flight allows the quenching of the different channels to be assessed. The 6Li(n,t)α channel is found to have its energy quenched to 37(1)% relative to γ-ray detection, while the proton energy deposition spectrum is quenched to 60(1)%.

TLYC闪烁体的中子响应

测量了最近开发的Tl 2 LiYCl 6(Ce)闪烁体对中子的响应,并首次在材料中观察到35 Cl(n,p)通道。闪烁体暴露于安装在平行板雪崩计数器内的252 Cf震源,用于裂变碎片同时测量。质子和Ť+α用脉冲形状鉴别技术选择类事件。能量沉积和飞行时间的比较允许评估不同通道的淬灭。的6李(N,T)α 发现通道相对于通道的能量淬灭到37(1)% γ射线检测,而质子能量沉积谱被淬灭到60(1)%。
