ion pump

[′ī‚än ‚pəmp]
(electronics)
A vacuum pump in which gas molecules are first ionized by electrons that have been generated by a high voltage and are spiraling in a high-intensity magnetic field, and the molecules are then attracted to a cathode, or propelled by electrodes into an auxiliary pump or an ion trap.

Ion Pump

 

a vacuum pump in which the scavenged gas is subjected to intense ionization and the positively charged ions that form are removed by an electric field. Ion pumps create a vacuum of 10-4 newtons per sq m, or 10-6 mm of mercury.
