Both equipotential and ion path plots can be obtained. The program has proven extremely useful in numerous applications, ranging from mass spectrometer ion sources to setting up primary beam optics for organic SIMS. This report is a tutorial on its use, leading the user step-by-step through the various options. Examples are given, and a sample lens is analyzed and refined. Anyone with an interest in design of ion optics will benefit from acquiring and applying SIMION, either in its Fortran or its IBM-PC form. It is the former that is described here.
