Computer simulation of extraction and acceleration of ion beam

The simulation of the extraction of ion beam with variously charged ions from high current ion sources MEVVA type has been used for investigation of the beam characteristics and optimization for specific application possibilities. A few examples are used to demonstrate the capabilities and limits of these simulations. The simulations are in a good agreement with experimental results and can provide the basis for optimizing the extraction system and acceleration gap for source and for decrease of losses of the extracted beam.
