This proposal addresses the question: What is the source of the matter/anti-matter asymmetry in the universe? The technical name for this asymmetry is "CP Violation" and the R&D proposed here will be an important step to determine if neutrinos can be an important part of the answer.Specifically, a next generation neutrino oscillation experiment which sends a neutrino beam from Fermilab to NSF's proposed Deep Underground Science and Engineering Laboratory (DUSEL) can address this question. A new type of detector will be necessary, however. The proposed detector is known as a Liquid Argon Time Projection Chamber (LArTPC).This proposal will investigate the capability and feasibility of this detector at useful energies. This proposal seeks to build and operate a prototype detector. This is an important next step in the R&D path towards building a massive LArTPC.The broader impacts of this proposal will bring junior high school teachers into this program as researchers. Further, the PI proposes to develop a school-year program for 6-8 grade girls which draws from this research program. It is noted that in the 6-8 grade, girls begin to perform more poorly than boys in math and science. The PI hopes that the focus on interesting girls in science at a pivotal time for their success will help to encourage them to pursue science.

这个提议解决了一个问题：宇宙中物质/反物质不对称的来源是什么？ 这种不对称性的技术名称是“CP破坏”，这里提出的研发将是确定中微子是否可以成为答案的重要组成部分的重要一步。具体来说，下一代中微子振荡实验可以解决这个问题，该实验将中微子束从费米实验室发送到美国国家科学基金会提议的深地下科学与工程实验室（DUSEL）。然而，一种新型的探测器将是必要的。该探测器被称为液氩时间投影室（LArTPC），本研究将探讨该探测器在有用能量下的性能和可行性。 该提案旨在建造和操作一个原型探测器。这是在研发道路上朝着建立一个大规模的LArTPC迈出的重要一步。这一建议的更广泛的影响将使初中教师作为研究人员参与这一计划。 此外，PI还建议借鉴这一研究方案，为6-8年级女生制定一个学年方案。值得注意的是，在6-8年级，女孩开始在数学和科学方面的表现比男孩差。PI希望在关键时刻关注科学领域有趣的女孩，这将有助于鼓励她们追求科学。
