AMoRE (Advanced Mo-based Rare process Experiment) is an experiment to search a neutrinoless double-beta decay of $^{100}$Mo in molybdate crystals. The neutron and muon-induced backgrounds are crucial to obtain the zero-background level (<$10^{-5}$ counts/(keV$\cdot$kg$\cdot$yr)) for the AMoRE-II experiment, which is the second phase of the AMoRE project, planned to run at YEMI underground laboratory. To evaluate the effects of neutron and muon-induced backgrounds, we performed Geant4 Monte Carlo simulations and studied a shielding strategy for the AMORE-II experiment. Neutron-induced backgrounds were also included in the study. In this paper, we estimated the background level in the presence of possible shielding structures, which meet the background requirement for the AMoRE-II experiment.

AMoRE 双β衰变实验的中子和介子诱导背景研究

AMoRE（Advanced Mo-based Rare process Experiment）是在钼酸盐晶体中寻找$^{100}$Mo的中微子双β衰变的实验。中子和介子诱导的背景对于获得 AMoRE-II 实验的零背景水平 (<$10^{-5}$ counts/(keV$\cdot$kg$\cdot$yr)) 至关重要，即AMoRE项目二期，计划在YEMI地下实验室运行。为了评估中子和介子诱导背景的影响，我们进行了 Geant4 Monte Carlo 模拟并研究了 AMORE-II 实验的屏蔽策略。研究中还包括中子诱导的背景。在本文中，我们估计了可能存在屏蔽结构的背景水平，这满足 AMoRE-II 实验的背景要求。
