1. A source of charged particles, comprising:
an inner hollow cylinder and an outer hollow cylinder with a gap between them, and
means for providing airflow with substance particles along surfaces of the cylinders forming the gap, the airflow directed from first butt ends of the cylinders to second butt ends of the cylinders,
wherein materials of surfaces of the hollow cylinders forming the gap are selected so as the substance particles and the surfaces obtain opposite electrical charges upon friction of the substance particles against the surfaces.
