  • Publication number: 20130195679
    Abstract: Disclosed is an ion pump system capable of efficaciously utilizing electrical fields and magnetic fields in all portions of a getter face, and thus of substantially improving exhaust efficiency. In particular, the present disclosure is based on the discovery that disposing a plurality of disc-shaped electrodes upon an internal casing (12) and further disposing a plurality of disc-shaped electrodes also upon an external casing (11) eliminates saddle points, allowing efficacious utilization of electrical fields and magnetic fields in all portions of the getter face, and thus substantially improving exhaust efficiency.
