This award supports the construction of an array of detectors that will be optimized for studies of low-energy, charged-particle reactions. The reaction studies to be conducted with the array will substantially improve our understanding of energy generation and nucleosynthesis in novae and X-ray bursts, impacting astronomical measurements and their interpretation. New low-energy radioactive ion beam facilities at Florida State University (FSU) and at the National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University (MSU) promise to provide a wide variety of low-energy beams of short-lived, proton-rich nuclei that have been previously unavailable. The instrument will bring substantial, new capabilities to the laboratories at FSU and MSU, and it will be a resource for the broader user base at those facilities. Similar infrastructure does not exist at those laboratories. The instrumentation will be developed and constructed at Louisiana State University (LSU) and FSU, and will be deployed for experiments at FSU, the NSCL, and possibly other facilities in the future. The proposed instrument will have a great impact on astrophysics, experimental nuclear physics capabilities in the U.S., and on the education and training of students. This project will heavily utilize both undergraduate and graduate students and will provide an important opportunity for these students to be involved in the hands-on development of state-of-the-art instrumentation in an area of national need. The project will also foster collaboration between the students and faculty at LSU, FSU, and MSU.

该奖项支持建造一系列探测器，这些探测器将被优化用于低能带电粒子反应的研究。将利用该阵列进行的反应研究将大大提高我们对新星和X射线爆发中的能量产生和核合成的理解，从而影响天文测量及其解释。佛罗里达州立大学(FSU)和密歇根州立大学(MSU)国家超导回旋实验室(NSCL)的新低能放射性离子束设施有望提供各种以前无法获得的短寿命、富质子核的低能离子束。该仪器将为佛罗里达州立大学和密歇根州立大学的实验室带来实质性的新能力，并将成为这些设施更广泛的用户基础的资源。这些实验室不存在类似的基础设施。该仪器将在路易斯安那州立大学(LSU)和佛罗里达州立大学(FSU)开发和建造，并将在未来部署在FSU、NSCL和可能的其他设施进行实验。拟议中的仪器将对美国的天体物理、实验核物理能力以及学生的教育和培训产生重大影响。这个项目将大量利用本科生和研究生，并将为这些学生提供一个重要的机会，让他们参与国家需求领域最先进的乐器的实践开发。该项目还将促进路易斯安那州立大学、密歇根州立大学和密歇根州立大学的学生和教职员工之间的合作。
