摘要
核反应研究依赖于三个主要的物理组成部分:由设施提供的原子核束,用于测量出射粒子的探测系统,以及目标。因此,目标制造是研究动力恒星反应和探索核结构演变的关键方面。JENSA (Jet Experiments in Nuclear Structure and Astrophysics)气体喷射靶是目前世界上用于稀有同位素束反应研究的密度最大的氦喷射靶,提供了氦、氮、氖等气态元素的靶。简要介绍了JENSA的设计和运行,包括调试和最近的科学实验,并讨论了JENSA与专用后坐力分离器SECAR耦合的未来。
Nuclear reaction studies rely on three main physical components: the beam of nuclei provided by the facility, the detector systems used to measure the outgoing particles of interest, and the target. Target fabrication is thus a critical aspect of studying the reactions that power stars and probe the evolution of nuclear structure. The Jet Experiments in Nuclear Structure and Astrophysics (JENSA) gas jet target is the most dense helium jet target for rare isotope beam reaction studies in the world, providing targets of gaseous elements such as helium, nitrogen, and neon. A brief overview of the design and operation of JENSA, including commissioning and recent science experiments, and a discussion the future of JENSA coupled to the dedicated recoil separator SECAR, are presented.
