捕获和冷却高电荷离子的原子物理学实验

Atomic physics experiments with trapped and cooled highly charged ions

H. -J. Kluge, W. Quint, D. F. A. Winters

摘要:

在原子物理学的许多基础实验中,俘获和冷却技术已成为非常重要的技术。当应用于高电荷离子限制在潘宁陷阱,这些程序是非常有效的测试量子电动力学在极端的电磁场产生的重高电荷离子,如铀U $^{91+}$。此外,在这些简单的系统中,可以高精度地确定基本常数或核的基态性质。最后,通过研究单个俘获的放射性离子,可以通过观察母体同位素信号的消失和子体同位素信号的出现来详细研究其核衰变。目前正在GSI建造的HITRAP设施将使这种在极低能量下对高电荷离子进行的实验成为可能。还将简要介绍预计将于2014年投入运行的未来反质子和离子研究设施。

英文摘要:

Trapping and cooling techniques have become very important for many fundamental experiments in atomic physics. When applied to highly charged ions confined in Penning traps, these procedures are very effective for testing quantum electrodynamics in extreme electromagnetic fields produced by heavy highly charged ions such as uranium U$^{91+}$. In addition, fundamental constants or nuclear ground state properties can be determined with high accuracy in these simple systems. Finally, by studying a single trapped radioactive ion, its nuclear decay can be studied in detail by observing the disappearance of the signal of the mother and the appearance of that of the daughter isotope. Such experiments on highly charged ions at extremely low energy will become possible by the HITRAP facility which is currently being built up at GSI. Also the future Facility for Antiproton and Ion Research (FAIR) will be briefly described which is expected to be operational by 2014.
