    • An ion pump includes one or more anode pump cells, a cathode positioned in proximity to the one or more anode pump cells and a magnet assembly 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 of opposite polarities disposed on opposite ends of the anode pump cells and secondary magnets disposed on opposite sides of the anode pump cells. The magnet assembly may further include a magnet yoke 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.

    • Diode sputter ion pumps display instabilities like current bursts, leakage currents and arcs typically following pumping exposure to gas doses greater than the ultimate pressure of the vacuum system in which the pump is operating. The instabilities are disruptive to the devices to which the sputter ion pump is attached. The invention provides an ion pump that exhibits improved stability and reduced leakage current. The instabilities are caused by explosive arc emission and electron emission from structures like dendritic protrusions that grow on the cathode plate, whose shape and placement give rise to high electric fields. According to the invention the cathode includes a sputterable material for removing gases from the environment of the ion pump and shaped so that during operation of the ion pump the electric field in a dendritic growth region is insufficient to cause field emission from the dendrites thereby reducing instabilities in the operation of the ion pump.
