acronym: FIB
https://doi.org/10.1351/goldbook.12411
Ionization of any species by the interaction of a focused beam of ions, with a translational energy of several thousand \(\pu{eV}\), with a solid or liquid sample.
Note: For a liquid sample, fast ion bombardment is the same as liquid secondary ionization.
