MRI-R2: Development of a Detection System for the Recoil Mass Separator St. George

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。该奖项将支持圣乔治大学正在建造的反冲质量分离器(RMS)探测系统的开发。圣乔治均方根将用于将逆运动学中的(α，伽马)反应产物从未反应的束流粒子中分离出来。圣乔治被设计为抑制束流粒子的10^12倍。即使有这样的抑制，相当数量的反应产物和未反应的束流粒子也将被送到均方根圣乔治的末端。拟议的探测系统将使用能量和飞行时间的测量来区分不同的反应产物和束流粒子。拟议的系统将涉及核天体物理学的一个广泛项目。拟议探测器系统的开发和使用将有助于在项目期间进行多层次的研究培训，尤其是通过博士后、研究生和本科生的实验工作。

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.
