Collaborative Research for DUSEL: Gas Xe R&D for EXO

该奖项是为了表彰斯坦福大学和阿拉巴马大学之间的一项合作研究和开发项目，该项目旨在研究一种高压气相探测器的可行性，该探测器使用富集氙来探测无中微子的双β衰变。研究和开发将在更广泛的EXO合作中进行，通过引入标记来推进液体氙的检测，并使用低背景的氙进行高压气相检测。支持者设想在液体探测器上应用钡标记，以大大减少放射性背景，并允许前所未有的灵敏度进行明确的测量。这项工作将主要由斯坦福大学小组进行。气体探测器的发展不如液体探测器先进，来自阿拉巴马大学的研究小组将探索这种探测器的特点。预计项目完成后，将有成果指导深地下科学工程实验室吨级无中微子双β衰变实验的探测器研制和技术选择。

This award is for a collaborative research and development undertaking between the University of Stanford and the University of Alabama towards the feasibility of a high pressure gas phase detector using enriched Xenon for the detection of neutrino-less double beta decay. Research and Development is to proceed within the broader EXO collaboration to advance detection with liquid Xenon by the introduction of tagging and to a high pressure gas phase using Xe with low background. The proponents envision applying tagging with Barium for the liquid detector to drastically reduce the radioactive background and allow an unambiguous measurement of unprecedented sensitivity. This work will be mainly carried out by the University of Stanford group. The developments of the gaseous detector are not as advanced as the liquid case and the group from the University of Alabama will be exploring the characteristics of such a detector. It is expected that at completion of this project, there will be results to guide the detector development and technology selection for the ton-class of neutrino less double beta decay experiments for the Deep Underground Science & Engineering Laboratory.
