Papers on using SIMION with Paul Traps¶
Papers on simulating Paul and multipole traps with SIMION would be too numerous to list here (hundreds or maybe thousands), but let’s add a few. If you have a paper, let us know to add it to this list. Search Google Scholar for more.

Unlike conventional ITs, in which hyperbolic metal electrodes establish equipotential boundary conditions, electric fields in the halo IT were established by applying different RF potentials to each ring.”
