原子和核物理学中的彭宁阱质谱法已成为测定原子质量的成熟且可靠的工具。它与短寿命放射性核素一起首次在欧洲核子研究中心的同位素质量分离器在线设施（ISOLDE）的ISOLTRAP中引入。潘宁阱在耦合到其他生产机制，如在飞行中的生产和分离系统中发现了新的应用。在原子和核物理学中的应用范围从核结构研究和理论方法的相关精确测试到描述强相互作用到电弱标准模型，量子电动力学和中微子物理学的测试，以及在核天体物理学中的应用。彭宁阱质谱法的成功是由于其精确度和准确度，即使对于低离子强度（即，低产量），以及其非常快的测量周期，使人们能够获得短寿命同位素。相对质量精度的电流范围超过δ m/ m=10−8，半衰期极限低至几毫秒，灵敏度约为阱中每分钟一个离子。我们提供了一个全面的概述的技术和潘宁阱质谱在核和原子物理学中的应用。
Penning-trap mass spectrometry in atomic and nuclear physics has become a well-established and reliable tool for the determination of atomic masses. In combination with short-lived radioactive nuclides it was first introduced at ISOLTRAP at the Isotope Mass Separator On-Line facility (ISOLDE) at CERN. Penning traps have found new applications in coupling to other production mechanisms, such as in-flight production and separation systems. The applications in atomic and nuclear physics range from nuclear structure studies and related precision tests of theoretical approaches to description of the strong interaction to tests of the electroweak Standard Model, quantum electrodynamics and neutrino physics, and applications in nuclear astrophysics. The success of Penning-trap mass spectrometry is due to its precision and accuracy, even for low ion intensities (i.e., low production yields), as well as its very fast measurement cycle, enabling access to short-lived isotopes. The current reach in relative mass precision goes beyond δ m/ m=10−8, the half-life limit is as low as a few milliseconds, and the sensitivity is on the order of one ion per minute in the trap. We provide a comprehensive overview of the techniques and applications of Penning-trap mass spectrometry in nuclear and atomic physics.
