Collaborative Research: Contributions to HALO, the Helium and Lead Observatory

这一奖项将使杜克大学和明尼苏达大学德卢斯大学的中微子研究小组在氦和铅天文台(HALO)上进行合作。这是一项新的实验，旨在探测起源于我们银河系内核心塌缩超新星的中微子。造成这些灾难性事件的大质量恒星的死亡每隔几十年就会发生在MilkyWay的某个地方，并以中微子短爆发的形式释放出99%的能量。现有的探测器主要对电子反中微子敏感。使用铅作为其目标原子核，使光晕对电子中微子以及通过中性电流相互作用的爆发通量的所有风味成分都很敏感。这一资金周期的努力将集中在为Halo升级冗余、快速故障转移数据采集系统。该奖项将为这一努力提供适度的硬件和人员贡献。该奖项的广泛影响包括对学生和博士后研究人员的出色实验培训。在过去，他们非常成功地让学生和博士后参与进来。该项目提供了一系列经验，从模拟到探测器建造，以及即将开始的操作和数据分析。光晕也将成为SNEWS(超新星早期预警系统)的贡献者，SNEWS有一个内在的外展部分。

This award will enable collaborative work by Duke University and the University of Minnesota Duluth's neutrino research groups on the Helium and Lead Observatory (HALO). This is a new experiment designed to detect neutrinos originating in a core-collapse supernova within our own galaxy. The deaths of massive stars which cause these cataclysmic events occur every few decades somewhere in the MilkyWay and emit 99% of their energy in the form of a short burst of neutrinos. Existing detectors are primarily sensitive to electron antineutrinos. Use of lead for its target nuclei allows HALO to be sensitive to electron neutrinos, as well as to all flavor components of the burst flux via neutral current interactions. The effort for this funding cycle will center on upgrading HALO with redundant, fast-failover data acquisition systems. This award will provide modest hardware and personnel contributions to this effort.Broader impacts of this award include the excellent experimental training for students and postdoctoral researchers. They have been very successful in involving students and postdocs in the past. This project offers a range of experiences, from simulation through detector construction, with operations and data analysis to commence soon. HALO will also be a contributor to SNEWS (SuperNova Early Warning System), which has an intrinsic outreach component.
