本文给出了DAMA/LIBRA实验中μ子诱导本底的精确模拟。μ子采样地下已进行使用MUSIC/MUSUN代码和随后的相互作用在岩石周围的DAMA/LIBRA探测器洞穴和实验装置,包括屏蔽,已与GEANT 4模拟。9.6.总的来说,我们模拟相当于20年的μ子数据。我们计算了DAMA/LIBRA探测器腔中μ子感生的总中子通量为Φ μ n= 1.0× 10-9 cm-2s-1,与其它模拟结果一致。在选择满足DAMA/LIBRA信号标准的事件后,我们的模拟预测了3.49× 10- 5cpd/kg/keV,占不到0.3%的DAMA/LIBRA调制幅度。我们的结论是,从我们的工作,μ子诱导的背景是无法有助于所观察到的信号调制。
We present an accurate simulation of the muon-induced background in the DAMA/LIBRA experiment. Muon sampling underground has been performed using the MUSIC/MUSUN codes and subsequent interactions in the rock around the DAMA/LIBRA detector cavern and the experimental setup including shielding, have been simulated with GEANT4. 9.6. In total we simulate the equivalent of 20 years of muon data. We have calculated the total muon-induced neutron flux in the DAMA/LIBRA detector cavern as Φ μ n= 1.0× 10-9 cm-2 s-1, which is consistent with other simulations. After selecting events which satisfy the DAMA/LIBRA signal criteria, our simulation predicts 3.49× 10-5 cpd/kg/keV which accounts for less than 0.3% of the DAMA/LIBRA modulation amplitude. We conclude from our work that muon-induced backgrounds are unable to contribute to the observed signal modulation.
