Thermionic emission generate electrons, which collide with gas atoms and generate positive ions.
Incident ENAs interact with a surface such as tungsten to generate ions that are then analyzed by an ion spectrometer.
A recent addition is a collection of plasma balls, spheres of living lightning that contain an antenna which generates fluorescent ions.
He noted that when the equipment generated negative ions, his colleague's mood was upbeat.
Most commercial air purifiers are designed to generate negative ions.
Plasma and ion sources generate ions of all species at energies between 10 eV and 50 MeV.
