摘要

为了研究中子和伽马辐射对高能物理（HEP）探测器所用材料特性的影响，我们设计并建造了一个基于国家科学中心 KIPT LUE-40 电子直列加速器的光中子源。该源被用于以1014厘米-2的中子通量辐照LHCb实验中PLUME探测器的光学元件。研究显示了提高中子产率的方法，特别是通过安装额外的高 Z 金属壳。在电子能量为 85 MeV 时，中子产率超过一个电子的 10-2 中子。

LUE-40 LINAC BASED NEUTRON SOURCE FOR IRRADIATION TESTS OF HEP DETECTOR MATERIALS AND COMPONENTS

A photoneutrons source based on the NSC KIPT LUE-40 electron linac was designed and constructed to study the effect of neutron and gamma radiation on the properties of materials used in high-energy physics (HEP) detectors. The source was used to irradiate the optical elements of the PLUME detector in LHCb experiment with the neutron fluency of 1014 cm-2. Ways to increase the neutron yield, in particular, by installing an additional high Z metal shell are shown. At electron energy of 85 MeV, the neutron yield exceeds 10-2 neutron over one electron.
