Abstract

Axial aberration of the ion-optical system of a static mass analyzer is one of the factors limiting the transmittance and sensitivity of the device because of a need in significantly decreasing the vertical component of the ion beam emittance to get the required mass spectral resolution. We described an algorithm for selecting the optimal collimating system of the mass analyzer, which effectively decreases the contribution of axial aberration with minimal loss of the intensity of mass spectral lines.

静态质量分析仪垂直接受度的优化

摘要

静态质量分析器的离子光学系统的轴向像差是限制设备透射率和灵敏度的因素之一，因为需要显着降低离子束发射率的垂直分量以获得所需的质谱分辨率。我们描述了一种用于选择质量分析仪的最佳准直系统的算法，该算法可以有效地减少轴向像差的影响，同时使质谱线强度的损失最小。
