Properties of Bi LIMS with ion clusters
Original language description
The ion beams used in SIMS are produced by liquid?metal ion sources (LMIS) which provide fine, optically bright ion beams even for low emission currents around 1 .mu.A or less. The typical energy of the primary beam varies from 10 to 40 keV. The properties of the LMIS are strongly limited by the effect of the Discrete Coulomb Interactions (DCI) near the source. The DCI increase the energy width (Boersh effect) and decrease the brightness of the source due to the trajectory displacement effect. Contraryto the Ga LMIS which contains mostly only Ga+ ions, in case of the Bi LMIS the ion beam consists of several ion types and clusters of ions with similar currents. Because each ion type has different charge and mass they will be accelerated to different velocities, which increase the number of interactions and decreases the quality of the source. The aim of this contribution is a simulation of the effect of the clusters on the source properties based on the MC simulation.
