Abstract
Factors affecting the current-voltage characteristics of liquid metal ion sources are reviewed. The results demonstrate that ion emission is not controlled by space-charge effects but rather is determined by liquid flow limitations along the needle emitter. A hydrodynamic model is presented which predicts the experimental I-V characteristics. The model suggests that a reduction in the energy spread (Boersch Effect) of the emitted ions may be achieved by increasing the needle flow impedance.Keywords
