Abstract
A gas ion gun includes an anode electrode to remove electrons from a gas in order to create gas ions. The anode electrode includes a wire made of an electrical conductive material or of a semiconductor material, the wire extending along a longitudinal axis from a proximal end to a flattened distal end. The anode electrode further includes a crystal particle directly deposited on the flattened distal end, the electrical conductivity of the crystal particle being ten times smaller than the electrical conductivity of the wire.
