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