Paul traps (also known as radio-frequency traps or simply "ion trap") solely depend on electric fields to achieve ion trapping, as opposed to the Penning (FTICR) Traps. In order to trap ions, an dynamic quadrupolar field is required. The name Paul trap is derived from the inventor of the traps, the German physicist Wolfgang Paul (1913-1993), who was awarded the Nobel prize in physics in 1989 for the development of the traps.
