Workshop: Cosmic-Ray prOduced NUclide Systematics on Earth Project (CRONUS-Earth Project), December 3-4, 2002

本提案要求为为期两天的研讨会提供资金，以便将广泛的国际从业者和就地生产的宇宙射线核素的使用者聚集在一起，以建立克罗诺斯-地球项目。该项目的想法源于拉蒙特-多尔蒂地球天文台于2002年3月17-19日举办的一次最初的研讨会。第一次会议的目的是概述最新技术的现状，并制定一份需要解决的科学问题清单，以便将该技术投入常规使用。第二次研讨会的目标是传播有关科学状况的一般信息，为第一次研讨会中没有讨论的项目的新方面征求意见，并为提交给国家科学基金会和欧盟的最终克罗诺斯-地球项目拟定大纲。由于这次研讨会将汇集来自世界各地的该领域的大多数领导者，我们预计，除了CRONUS-地球的提议外，我们将能够在没有克罗诺斯-地球将提供的数据的情况下制定使用该技术的指导方针。这本身就应该对整个社区有很大的帮助，因为目前这种异常强大的技术的应用在不同的小组或实验室之间并不统一。因此，这个论坛所能提供的讨论和宣传至少将使社区更清楚地了解这一极其重要的工具，包括它的潜力以及它目前的局限性。

ABSTRACTThis Proposal requests funding for a 2-day workshop to bring together a broad international community of practitioners and users of in situ produced cosmic-ray nuclides to build the CRONUS-Earth project. The idea for the project grew out of an initial workshop hosted by Lamont-Doherty Earth Observatory on 17-19 March 2002. This first meeting was directed at outlining the state of the art and formulating a list of scientific problems that needed to be addressed in order to bring the technique into routine usage. The goal of this second workshop, is to disseminate general information about the state of the science, to solicit ideas for new aspects of the project that were not addressed in the first workshop and to formulate an outline for the final CRONUS-Earth project to be submitted to the NSF and EU. As this workshop will bring together most of the leaders in the field from around the world we anticipate that aside from theCRONUS-Earth proposal, we will be able to formulate guidelines for the use of the technique in the absence of the data that CRONUS-Earth will provide. This alone should be of great use to the community as a whole, as presently the application of this singularly powerful technique is not uniform across groups or labs. Thus, at a minimum, the discussion and outreach that this forum can provide will give the community a clearer view of this extremely important tool both with respect its potential, as well as to its present limitations.
