Based on the analysis of the results of the study of various designs of multi-electrode harmonized Kingdon traps, we propose a new type of trap with two merged internal electrodes that has the ability to capture and accumulate ions formed inside. We also investigated the influence of inaccuracies in the manufacture of the electrodes on the field inside such trap. The four-electrode trap, which actually degenerates into a two-electrode device with traces of two other electrodes present at the ends of the internal electrodes (their splitting) has been found as the less sensitive to inaccuracies caused by manufacturing and cutting the ends of trap electrodes. We show that a mass spectrometer with a relatively high resolving power can be created on the basis of such a trap. The creation of the traps requires the manufacture of complex electrodes with demanded accuracy of their surfaces. This becomes possible with the advent of 3D printers.

在对多种设计的多电极协调式金登阱的研究结果进行分析的基础上，我们提出了一种新型的阱，该阱具有两个合并的内部电极，能够捕获和累积内部形成的离子。我们还研究了电极制造过程中的误差对这种阱内部电场的影响。发现四电极阱实际上退化为两电极器件，在内部电极的端部存在两个其他电极的痕迹（它们的分裂），因为它们对制造和切割端部造成的误差不那么敏感。陷阱电极。我们表明，可以在这种阱的基础上创建具有相对较高分辨能力的质谱仪。陷阱的产生要求制造复杂的电极，并要求其表面具有精确度。随着3D打印机的出现，这成为可能。
