霍姆斯塔克桑福德地下实验室的Cosmic Ray μ子通量
Cosmic Ray Muon Flux at the Sanford Underground Laboratory at Homestake
摘要：
测量μ介子通量对霍姆斯特克的桑福德地下实验室很重要，该实验室正在计划进行几项低本底实验。该实验室在三个位置测量了接近垂直的宇宙射线μ子通量：在表面（1.149 \pm 0.017 x 10^-2 cm^-2 s^-1 sr^-1），在800英尺（0.712 km w.e.）水平（2.67 \pm 0.06 x 10^-6 cm^-2 s^-1 sr^-1），在2000英尺（1.78 km w.e.）水平（2.56 \pm 0.25 x 10^-7 cm^-2 s^-1 sr^-1）。这些通量与模型预测吻合得很好。
英文摘要：
Measuring the muon flux is important to the Sanford Underground Laboratory at Homestake, for which several low background experiments are being planned. The nearly-vertical cosmic ray muon flux was measured in three locations at this laboratory: on the surface (1.149 \pm 0.017 x 10^-2 cm^-2 s^-1 sr^-1), at the 800-ft (0.712 km w.e.) level (2.67 \pm 0.06 x 10^-6 cm^-2 s^-1 sr^-1), and at the 2000-ft (1.78 km w.e.) level (2.56 \pm 0.25 x 10^-7 cm^-2 s^-1 sr^-1). These fluxes agree well with model predictions.
