Numerical analysis and optimization of radio-frequency ion trap potential

Abstract The trap of multi-ion frequency standard is an ideal candidate for a new generation ground and space-borne timekeeping systems, which has high signal-to-noise ratio, low drift rate excellent long-term stability. non-ideal characteristic radio-frequency potential one the dominant factors that restrict performance ion standard. In this study, finite element numerical analysis method used to quantitatively analyse optimize electrical field trap, analytical model trapping established. typical transient surface decoupling various effects. Based on optimal structure parameters, non-standard are established verify validity accuracy method. This can provide quantitative solution precision reconstruction heterotype traps.
