Development of Apparatus for Nuclear Astrophysics Utilizing Stable and Unstable Nuclear Beams

密歇根大学和圣母大学将联合开发一种独特的仪器，这将使低能核反应研究成为更好地了解天体物理过程中能量的产生和元素的合成的关键。后者包括大爆炸核合成以及恒星和超新星(爆炸恒星)中能量和重元素的产生。改进的核测量将有助于澄清天体物理学中存在的一些悬而未决的谜团。建议的装置将包括一个小但高强度的静电离子加速器，与一个专门设计的高效磁探测设备相耦合。后者将由两个大型超导磁体组成，这两个磁体将在美国设计和建造，与美国的一个工业合作伙伴合作。拟议中的设备将是位于圣母大学的中西部低能核加速器设施的一部分。该设施的一个独特功能是生产相对强烈、寿命较短的不稳定核束，用于研究与爆炸性核合成有关的反应。新仪器还将用于原子物理、生物物理和材料科学的新型应用研究。它将服务于邻近地区的十几所或更多的大学和学院，本科生、研究生和来自这些机构(密歇根大学、圣母大学、奥伯林学院、俄亥俄州立大学、印第安纳大学-SO)的教职员工将广泛参与。班德，肯塔基州大学，希望学院，密歇根州立大学，伊利诺伊州大学，...)。

A unique type of apparatus will be developed jointly by the University of Michigan and Notre Dame University that will permit studies of low-energy nuclear reactions key to better understanding the production of energy and synthesis of the elements in astrophysical processes. The latter include BigBang nucleosynthesis and the production of energy and heavy elements in stars and supernovae (exploding stars). Improved nuclear measurements will help clarify some of the outstanding mysteries that exist in astrophysics. The proposed apparatus will consist of a small but highintensity electrostatic ion accelerator coupled to a specially designed, high-efficiency magnetic detection device. The latter will consist of two large superconducting magnets which will be designed and built in the U.S. as a collaborative effort with a U.S. industrial partner. The apparatus proposed will be part of a Midwest low-energy nuclear accelerator facility located at the University of Notre Dame. A unique feature of the facility will be the production of relatively intense, short-lived unstable nuclear beams for the study of reactions related to explosive nucleosynthesis. The new apparatus will also be available for new types of applied research in atomic physics, biophysics and materials science. It will serve a dozen or more universities and colleges in the immediate area with extensive participation by undergraduates, graduate students, and faculty from those institutions (U. Michigan, U. Notre Dame, Oberlin College, Ohio State U., U. Indiana-So. Bend, U.W. Kentucky, Hope College, MSU, U. Illinois,...).
