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 × 10 cm2) 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 ± 0.034(stat.) ± 0.279(syst.)%.

使用钆阴极气体电子倍增器检测器进行中子检测

已经开发了带有钆阴极的气体电子倍增器 (GEM) 探测器，以探索其作为中子探测器的潜在应用。它由三个标准尺寸（10 × 10 cm2）的 GEM 箔和一个用作阴极的钆薄板组成，用作中子转换器。测量了两种不同阴极设置和两种不同漂移间隙的中子检测效率。韩国标准科学研究院（KRISS）的热中子源用于测量中子探测效率。根据 KRISS 测量的中子通量，我们钆 GEM 探测器的中子探测效率为 4.630 ± 0.034(stat.) ± 0.279(syst.)%。
