Electron beam ion trap

Schematics of an electron beam ion trap. Red: electron source filament, blue: electron beam, black: electrodes, green: magnet. The thin line represents the electric potential along the axis.

Electron beam ion trap (EBIT) is an electromagnetic bottle that produces and confines highly charged ions. An EBIT uses an electron beam focused with a powerful magnetic field to ionize atoms to high charge states by successive electron impact.

It was invented by M. Levine and R. Marrs at LLNL and LBNL.[1]
