Abstract
A source for generating singly and/or multiply charged ions composed essentially of a glow cathode, an intermediate electrode and an anode electrode having a common axis of symmetry and bordering a gas discharge chamber and each presenting a passage opening coaxial with the axis of symmetry, and a system producing a magnetic field having an axial component along the axis of symmetry, with the anode electrode opening being at a location where the magnitude of the axial component of the magnetic field is substantially equal to its maximum value.
