The work is the development of the ion optics analyzer of an ion mass spectrograph, REFIMS, for use in near-space and space, on various upcoming missions. The goal is to improve the resolution and precision of the mass spectrum reading, by adjusting the shape, spacing, and voltages of the electrodes. The electrodes, which make up the ion optics analyzer, generate electrostatic lenses, which guide the trajectories of the ions through the instrument. A complete discussion of the operating principles of REFIMS, and the theory of ion optics, in general, is provided. This presentation also explains how Solidworks and the ion optics simulation software, Simion, were used to design the ion optics analyzer. Data from these simulations will show how far development has progressed towards the goal of focusing the instrument such that it is precise to a single atomic mass unit, up to 80 atomic mass units.
