ion trap

[′ī‚än ‚trap]
(electronics)
An arrangement whereby ions in the electron beam of a cathode-ray tube are prevented from bombarding the screen and producing an ion spot, usually employing a magnet to bend the electron beam so that it passes through the tiny aperture of the electron gun, while the heavier ions are less affected by the magnetic field and are trapped inside the gun.
A metal electrode, usually of titanium, into which ions in an ion pump are absorbed.
