This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This award will support the development of a detection system for the recoil mass separator (RMS), St George, which is being constructed at the University of Notre Dame. The RMS St George will be used to separate products of (alpha, gamma) reactions in inverse kinematics from unreacted beam particles. St George is designed to suppress beam particles by a factor of 10^12. Even with that suppression, comparable numbers of reaction products and unreacted beam particles will be delivered to the end of the RMS St George. The proposed detection system will use measurements of both energy and time-of-flight to distinguish between the various reaction products and beam particles. A broad program in nuclear astrophysics will be addressed with the proposed system. The development of the proposed detector system and its use will contribute to research training at many levels during the project duration and even more so through the experimental work by post-docs, graduate students, and undergraduates.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该合同将支持圣乔治反冲质量分离器（RMS）探测系统的开发，该系统正在圣母大学建造。RMS St George将用于分离（α, γ）逆运动学反应的产物和未反应的束粒子。圣乔治被设计成将光束粒子抑制10^12倍。即使有这种抑制，相当数量的反应产物和未反应的束粒子将被输送到RMS圣乔治的末端。提出的检测系统将使用能量和飞行时间的测量来区分各种反应产物和束粒子。一个广泛的程序在核天体物理学将处理与拟议的系统。所提出的探测器系统的开发和使用将有助于在项目期间的多个层次的研究训练，甚至通过博士后、研究生和本科生的实验工作。
