a Workshop on Neutrino Geoscience 2008

中微子地球科学研讨会将于2008年9月在萨德伯里中微子天文台（SNOLab）举行。这次为期2.5天的会议将有地质学和粒子物理学的讨论，重点是全球和加拿大地质学的最新发展，以及在SNO（萨德伯里中微子天文台）、卡姆兰和博雷西诺进行的地球中微子实验。将有大约60名参与者，两个社区的代表人数大致相等。参观SNO地下设施，包括SNO+实验环境。这次会议将使北美地质和粒子物理学界参与进来，努力促进合作研究。粒子物理学界寻求地质学界的反馈和见解，以了解最近500公里半径内的K、Th和U含量，即SNO+探测器下方的半球形体积。会议组织者包括博士。Mark Chen（加拿大安大略省皇后大学）、Claude Jaupart（法国巴黎大学）、Bill McDonough（美国马里兰大学）和Roberta Rudnick（美国马里兰大学）。在利用反中微子探测在地质和防扩散方面的实际应用，特别是在反应堆监测方面取得了重大进展。尽管取得了这些显著的成就，但这些相互关联的社区只有适度的重叠。因此，应用和基础反中微子物理学领域缺乏一个总体战略，无法有效利用每个利益相关者提供的资源和优势。本次研讨会旨在为基础和应用反中微子物理界（包括地球科学）之间的利益战略结盟奠定基础。更广泛的影响：地球中微子信号代表了对全球反中微子信号的背景贡献，其中还包括来自核反应堆和与武器有关的核材料的贡献。因此，对地微中子的详细了解有助于防止核扩散目的的反中微子探测的可行性。一些应用对于维持使用这类核材料的安全社会具有潜在的重要意义。智力优势：本次研讨会的重要性在于将不同的多学科科学家团体联合起来，共同致力于反中微子探测研究和应用。讲习班的一个目标是在这些领域之间建立更牢固的联系。为了充分了解反中微子频谱的各种组成部分并正确识别信号的来源，这一步是必要的。

A Workshop on Neutrino Geoscience will be held in September 2008 at SNOLab (Sudbury Neutrino Observatory Laboratory). This 2.5-day meeting will have geology and particle physics talks focused on recent developments in global and Canadian geology, and geoneutrino experiments at SNO (Sudbury Neutrino Observatory), KamLAND and Borexino. There will be ~60 participants, with roughly equal representation from both communities. There will be a tour of the SNO underground facility, including a view of the SNO+ experimental environment. This meeting will engage the North American geological and particle physics communities in an effort to foster collaborative research. The particle physics community seeks feedback and insights from the geological community in regards to knowledge about the K, Th and U content in the nearest 500 km radius, half-spherical volume beneath the SNO+ detector. The meeting organizers include Drs. Mark Chen (Queens University, Ontario, Canada), Claude Jaupart (University of Paris, France), Bill McDonough (University of Maryland, USA) and Roberta Rudnick (University of Maryland, USA). Significant progress has been made in exploiting the practical utility of antineutrino detection for geological and nonproliferation purposes, in particular, reactor monitoring. Despite these remarkable successes, these inter-related communities have had only modest overlap. As a result, the fields of applied and basic antineutrino physics lack an overarching strategy that would allow efficient exploitation of the resources and strengths provided by each stakeholder. This workshop aims to develop the basis for such a strategic alignment of interests between the fundamental and applied antineutrino physics communities, including geosciences.Broader Impact: The geonneutrino signal represents a background contribution to a global antineutrino signal, which also includes contributions from nuclear reactors and weapons related nuclear materials. Thus, understanding in detail the geoneutrino contributes greatly to the viability of antineutrino detection for nuclear nonproliferation purposes. Some applications are potentially important to maintaining a safe society that uses such nuclear materials. Intellectual Merit: The importance of this workshop will be to unite disparate groups of multi-disciplinary scientists with shared goals in antineutrino detection research and applications. A goal of the workshop is to develop stronger bonds of communications between these fields. This step is necessary in order to fully understand the various the components of an antineutrino spectrum and identify correctly the sources of the signal.
