摘要： 随着离子囚禁技术和激光冷却技术等发展，量子频标从微波频段向光频段跨越，离子光频标的不确定度最高提升至E-19量级。离子囚禁系统是实现离子光频标的核心体系之一，主要采用保罗离子阱产生的射频场和静电场来束缚离子。基于保罗离子阱囚禁势作用，阐述了离子运动方程和运动规律，重点探究了离子阱结构的研究进展，包括环帽阱、端帽阱、微型分段阱和刀片阱等。最后概括了离子阱的发展趋势，向着进一步提升光频标性能和促进光频标小型化等方向发展。

Abstract: With the development of ion confinement technology and laser cooling technology,the quantum frequency standard is developed from microwave band to optical band,and the uncertainty of ion optical frequency is raised to E-19 magnitude.The ion confinement system is one of the core systems for realizing ion optical frequency standard,which mainly applies the Paul trap to confine ions by the radio frequency field and electrostatic field.We introduce the principle of Paul trap and the equations of ion’s motion.Recent progresses on the ion trap structure in optical frequency standard have been presented,including ring-cap traps,end-cap traps,miniature segmented traps and blades traps.The development of ion traps can help promoting the stability and miniaturization of optical frequency standard.

Key words: Paul trap, Ion motion, Optical frequency standard
