Collaborative Research of the Joint Institute for Nuclear Astrophysics

作为JINA合作的一部分，该提案旨在改进与恒星氢和氦燃烧情景中的核合成相关的核反应的实验研究。测量是在圣母大学的KN&AMP；JN强流加速器上进行的。其中一项测量将是研究Nena循环中的反应，这对于恒星演化后期的氢壳燃烧和新星中爆炸性的氢燃烧都是重要的。对于氦燃烧，实验将集中在恒星演化的巨型阶段和超新星激波锋中的恒星中子源的测量。这些实验旨在以互补的方式使用正运动学和逆运动学。测量将使用弧循环气体-靶系统进行，该系统可以用不同的轻、重靶气体材料(H、He、Ne)操作。反应产物将用一套用于伽马辐射的Ge-三叶草探测器和一个专用的用于粒子的硅条探测器阵列来测量。

The proposal aims as part of the JINA collaboration at the improvedexperimental study of nuclear reactions, relevant for the nucleosynthesis in stellar hydrogen and helium burning scenarios. The measurements are performed at the KN&JN high currentaccelerators at the University of Notre Dame. One ocus of the measurements will bethe study of reactions in the NeNa cycle which is of importance forhydrogen shell burning during late stellar evolution and also for explosivehydrogen burning in novae. For helium burning, the experiments willconcentrate on the measurement of stellar neutron sources during thered giant phase of stellar evolution and in supernovae shockfronts.The experiments are designed for using forward and inversekinematics in a complementary manner. The measurements will be performed using are-circulating gas-target system which can be operated with differentlight and heavy target gas material (H,He,Ne). The reaction productswill be measured with a set of Ge-clover detectors for gamma-radiationand a dedicated Si-strip detector array for particles.
