Experiments with the TITAN mass measurement system

原子核的质量是许多物体系统最基本的性质之一。对群众的精确了解为检验和提炼先进的核理论和模型提供了条件，并促进了它们的进一步改进。在核β衰变的弱相互作用研究的测试中，以及在极端情况下的核结构的敏感测试中，质量是关键因素。此外，在核天文物理领域，需要原子质量来了解宇宙中铁以外的元素的合成。多年来，人们一直在努力准确地确定质量，但随着离子陷阱与放射性束(RIB)设施耦合的出现，这一领域已经发生了革命性的变化。到目前为止，大多数RIBE设备都有基于离子陷阱的质量测量系统，其中最先进的质量测量设备之一是泰坦。

The mass of the atomic nucleus is one of the most fundamental properties of such many body systems. Precise knowledge of masses provides for testing and refining of advanced nuclear theory and models and stimulate their further improvements. Masses are key ingredient in the tests of weak interaction studies in nuclear beta-decay, and for sensitive tests of nuclear structure at the extremes. Moreover, in the field of nuclear astro-physics, atomic masses are needed for an understanding of the synthesis of the elements beyond iron in the universe. There has been substantial effort to determine masses accurate and precise for many year, but with the advent of coupling ion traps to radioactive beam (RIB) facilities, the field has been revolutionized. By now most RIB facilities have ion trap based mass measurement systems, and one of the most advanced facilities for mass measurements is TITAN.
