a Workshop on Neutrino Geoscience 2008

中微子地球科学讲习班将于2008年9月在萨德伯里中微子天文台SNOLab举行。这次为期两天的会议将举行地质学和粒子物理讲座，重点讨论全球和加拿大地质的最新发展，以及萨德伯里中微子天文台、卡姆兰德和Borexino的地球中微子实验。将有大约60名参与者，来自两个社区的代表大致相等。将参观SNO地下设施，包括观看SNO+实验环境。这次会议将吸引北美地质和粒子物理界的参与，努力促进合作研究。粒子物理界寻求地质界关于SNO+探测器下方最近500公里半径的半球形体积内K、Th和U含量的知识的反馈和见解。会议组织者包括加拿大安大略省皇后大学的Mark Chen博士、法国巴黎大学的Claude JauPart博士、美国马里兰大学的Bill McDonough博士和美国马里兰大学的Roberta Rudnick博士。在开发用于地质和防扩散目的的反中微子探测的实际用途，特别是反应堆监测方面，已经取得了重大进展。尽管取得了这些令人瞩目的成就，但这些相互关联的社区只有少量重叠。因此，应用和基础反中微子物理领域缺乏一种总体战略，能够有效地利用每个利益攸关方提供的资源和优势。该讲习班旨在为包括地球科学在内的基础和应用反中微子物理界之间的这种战略利益结盟奠定基础。广泛影响：地中微子信号是对全球反中微子信号的背景贡献，其中还包括核反应堆和与武器有关的核材料的贡献。因此，详细了解地中微子有助于为核不扩散目的进行反中微子探测的可行性。一些应用对维护使用此类核材料的安全社会具有潜在的重要意义。学术价值：这次研讨会的重要性将是联合不同的多学科科学家群体，他们在反中微子探测研究和应用方面有着共同的目标。研讨会的一个目标是加强这些领域之间的交流纽带。为了充分理解反中微子光谱的各种成分并正确识别信号的来源，这一步骤是必要的。

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.
