A Liquid Metal Ion Source (LMIS) is a type of ion source used primarily in various applications such as mass spectrometry, focused ion beam (FIB) systems, and ion implantation. The LMIS generates ions by the field evaporation or field ionization of a liquid metal that is contained in a small source chamber.
