论文摘要
通过在LBNE的Beam Simulation源代码G4LBNE版本V3R2P4和Monte Carlo中实现几何形状来研究球形阵列目标。为了与名义LBNE靶标进行比较，使用不同的参数产生了效率的远探测器中微子通量：球直径17mm和13mm，不同的纵向位置，两个相互作用长度，较小，较小，梁尺寸R/3和1.7mm，束从50美元$ $ m到1mm。 1.86的相互作用长度（901mm），直径为17mm，梁尺寸为1.7mm，从0-3.5 GEV较高的$ν_μ$通量最高为10 \％，并抑制高于3.5 GEV的能量的通量最高70 \％。
Spherical Array Target was studied by implementing the geometry in LBNE's Beam Simulation source code g4lbne version v3r2p4 and Monte Carlo. To compare with Nominal LBNE target, unoscillated Far Detector neutrino flux was produced using different parameters: sphere diameter 17mm and 13mm, different longitudinal positions, two interaction length and less, beam size R/3 and 1.7mm, and beam offset from 50 $μ$m to 1mm. The 1.86 interaction length (901mm), 17mm diameter target, with beam size 1.7mm gives higher $ν_μ$ flux up to 10\% from 0-3.5 GeV, and suppresses flux up to 70\% at energy higher than 3.5 GeV.
