用于长基线中微子实验的球阵靶研究

Study of Spherical Array Target for Long-Baseline Neutrino Experiment

Quynh M. Nguyen, Alberto Marchionni

摘要:

通过在LBNE的波束模拟源代码g4 lbne版本v3 r2 p4和蒙特卡罗中实现几何来研究球形阵列目标。为了与标称LBNE靶进行比较,使用不同的参数:球直径17 mm和13 mm,不同的纵向位置,两个相互作用长度及以下,束流尺寸R/3和1.7 mm,束流偏移从50 $μ$ m到1 mm,产生了非振荡远探测器中微子通量。在1.86 μ m靶长(901 mm)、17 mm靶径和1.7 mm束流尺寸下,在0 ~ 3.5 GeV范围内获得了高达10%的高通量$ν_μ$,在能量高于3.5 GeV时通量抑制高达70%。

英文摘要:

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.
