摘要
本文档是对2016年提交给JLab-PAC44的提案PR12-16-001“杰斐逊实验室束流_dump实验(BDX)中的暗物质搜寻”的更新,报告了在解决有关束流开启本底问题的进展。通过采用新的模拟工具FLUKA,并规划利用_dump周围现有屏蔽测量来自_dump的缪子通量,这些关切得以解决。首先,我们与杰斐逊实验室辐射控制组的专家协商,将详细的BDX实验几何结构实现到FLUKA模拟中。FLUKA模拟已与我们的GEANT4模拟直接比较,并在有效区域内显示一致。FLUKA相互作用包配合一组调谐的偏置权重,自然能够以极小概率生成可靠的粒子分布,从而预测束流_dump周围规划屏蔽之外探测器位置处的计数率。其次,我们制定了一项计划,在现有配置下对Hall-A_dump的缪子通量进行测量,以验证我们的模拟。
