Abstract: A source of atomic or molecular particles includes a source of ionised particles (1), an extraction electrode (2) and an einzel lens (3) to focus a beam of particles. A Wien filter (4) selects particles in said beam having a predetermined velocity and a charge exchange cell (7) neutralises the ionised particles prior to the extraction of non-ionised particles from the beam.
