Abstract
The variation with temperature of the ion mass spectra of a liquid metal alloy ion source (LMAIS) (Au77Ge14Si9) is reported. Analysis of our results suggests the co-existence of two different ion creation mechanisms for the doubly charged atomic ions. Whereas some doubly charged ions are post-ionised from the singly charged state, others are directly field-evaporated. The temperature dependence of the abundance of the ionic clusters emitted by the source has also been investigated.
