论文摘要
已经开发了具有gadolinium阴极的气体电子乘数(GEM)检测器,以探索其作为中子检测器的潜在应用。它由三个标准尺寸($ 10 \ times 10 $ cm $ {}^{2} $)宝石箔和一个薄的gadolinium板作为阴极,用作中子转换器。测量了两个不同的阴极设置和两个不同的漂移间隙的中子检测效率。韩国标准与科学研究所(KRISS)的热中子来源用于测量中子检测效率。基于克里斯(Kriss)测得的中子通量,我们的Gadolinium Gem检测器的中子检测效率为$ 4.630 \ pm 0.034(stat。)\ pm 0.279(Syst。)\%$。
A gas electron multiplier (GEM) detector with a gadolinium cathode has been developed to explore its potential application as a neutron detector. It consists of three standard-sized ($10\times 10$ cm${}^{2}$) GEM foils and a thin gadolinium plate as the cathode, which is used as a neutron converter. The neutron detection efficiencies were measured for two different cathode setups and for two different drift gaps. The thermal neutron source at the Korea Research Institute of Standards and Science (KRISS) was used to measure the neutron detection efficiency. Based on the neutron flux measured by KRISS, the neutron detection efficiency of our gadolinium GEM detector was $4.630 \pm 0.034(stat.) \pm 0.279(syst.) \%$.
