The Fourier transform ion cyclotron resonance method holds the lead in mass accuracy and resolving power among all other mass spectrometry methods. The dynamically harmonized cell is largely responsible for the supremacy. This cell has an ideal hyperbolic trapping potential after averaging over fast cyclotron motion. Recently we have introduced an open modification of the cell (especially useful with ultrahigh magnetic fields) and have found the analytical solution for the averaged potential inside it. The voltage on specific "regularizing" electrodes determines how close a potential is to the hyperbolic one. In this article, we find the optimal voltage on these "regularizing" electrodes analytically. This will assist with both further analysis and tuning of the trap after manufacturing.
傅里叶变换离子回旋共振方法在所有其他质谱方法中，在质量精度和分辨率方面占据领先地位。动态协调单元在很大程度上促成了这种优势。在对快速回旋运动进行平均后，该单元具有理想的双曲线捕获势。最近，我们引入了该单元的一种开放式改进（在超高磁场下特别有用），并找到了其内部平均势的解析解。特定“正则化”电极上的电压决定了势与双曲线势的接近程度。在本文中，我们通过解析方法找到了这些“正则化”电极上的最佳电压。这将有助于制造后对阱进行进一步分析和调谐。
