Abstract
A plasma source of charged particles includes a particle extraction control device consisting of an electrode having an exit hole in it and a planar solenoid arranged to produce, when energized, a magnetic field across the exit hole in the electrode, the magnitude of the magnetic field and potentials applied to extraction electrodes being variable so as to enable different charged particles to be emitted by the source.
