Nuclear Astrophysics at TRIUMF-ISAC: Stellar Burning Reaction Studies with DRAGON and TUDA

核天体物理学是从原子核之间相互作用的角度研究化学元素的起源，以及恒星如何发光、演化并最终消亡的学科。这些相互作用是我们用今天所有的天文仪器所看到的恒星中一切事物的主要潜在原因。为了全面了解它们，我们必须在实验室里探索原子核之间的相互作用，特别是地球上自然不存在的稀有同位素。这是使用粒子加速器、稀有的同位素束流和专门建造的专业设施来完成的，例如TRIUMF-ISAC的Dragon。TRIUMF-ISAC拥有一系列专门为核天体物理建造的世界级实验设施。最著名的是Dragon和TUDA设施，它们密切合作。天体物理学计划的首要主题是对恒星燃烧和爆炸中至关重要的核反应进行实验室测量。ISAC拥有一些地球上最好的稀有同位素束流，再加上Dragon和TUDA的世界级仪器，它是测量其中一些核反应的顶级实验室。该计划吸引了来自世界各地的研究人员，并为加拿大研究人员在核天体物理学领域处于领先地位并与世界联系提供了良好的基础。

Nuclear astrophysics is the study of both the origin of the chemical elements, and how stars shine, evolve and ultimately die, from the perspective of interactions between atomic nuclei. These interactions are the governing underlying reason for everything in stars that we see with all of today's pantheon of astronomical instruments. In order to understand them fully, we must explore the interactions between atomic nuclei in the laboratory, especially rare isotopes that don't exist on Earth naturally. This is done using particle accelerators, rare isotope beams, and purpose-built specialist facilities such as DRAGON at TRIUMF-ISAC. TRIUMF-ISAC hosts a range of world-class experimental facilities purposely built for nuclear astrophysics. Most well-known are the DRAGON and TUDA facilities, that operate in close collaboration. The overarching theme of the astrophysics program is the laboratory measurement of nuclear reactions critical in stellar burning and explosions. ISAC has some of the best rare isotope beams on the planet, and with the combination of that fact and the world-class instruments at DRAGON and TUDA, it is the top laboratory to go to for measurement of some of these nuclear reactions. The program attracts researchers from all over the world, and provides an excellent base for Canadian researchers to be at the top of the game in nuclear astrophysics and connect with the world.
