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.

原子核的质量是许多物体系统最基本的性质之一。对质量的精确了解有助于检验和改进先进的核理论和模型，并促进它们的进一步改进。质量是核β衰变中弱相互作用研究测试的关键因素，也是极端情况下核结构敏感测试的关键因素。此外，在核天体物理学领域，原子质量是理解宇宙中铁以外元素合成的必要条件。多年来，人们一直在努力准确和精确地确定质量，但是随着将离子阱耦合到放射性束（RIB）设施的出现，该领域已经发生了革命性的变化。到目前为止，大多数RIB设施具有基于离子阱的质量测量系统，并且用于质量测量的最先进设施之一是TITAN。
