ANALYTICAL POTENTIALS OF ELECTRIC FIELDS FOR SIMULATION OF ION GUIDES WITH A PERIODIC STRUCTURE

The article discusses analytical expressions for the potentials of electric fields that correspond to transport channels with a periodic geometric structure of electrodes and potentials applied to the electrodes. The electrodes of the transport channel are a sequence of circular diaphragms or have a similar structure. The derived expressions can be useful for rapid qualitative simulation of radio frequency devices used for ion conveying and focusing.
