Abstract: An electrostatic pump has two electrodes (13) spaced at a distance apart essentially in the direction of flow through the pump. A potential can be applied to the electrodes (13) in order to inject an ion current between them. The pump is further microminiaturized by arranging two semiconductor bodies (10) one above the other in the direction of flow through the pump. The semiconductor bodies are structured in such a way that the electrodes (13) form an integral component of the semiconductor bodies (10).

Abstract: An ion pump includes one or more anode pump cells (120a-120n), a cathode (124, 126) positioned in proximity to the one or more anode pump cells and a magnet assembly (140) for producing a magnetic field in the one or more anode pump cells. An electric field is applied between the cathode and the one or more anode pump cells. The magnet assembly includes primary magnets (142, 144) of opposite polarities disposed on opposite ends of the anode pump cells and secondary magnets (160-166) disposed on opposite sides of the anode pump cells. The magnet assembly may further include a magnet yoke (150) which provides a magnetic flux return path. The magnet assembly produces a substantially uniform axial magnetic field in the one or more anode pump cells.
