FIELD: physics.
SUBSTANCE: device for directing an ion beam along an essentially continuous beam line in at least one field which creates a force acting on the ions in the said ion beam, has at least one section having an essentially flat plate-like multi-terminal network having a top flat plate and bottom flat plate. Said force is essentially symmetrical in the parallel direction or essentially asymmetrical in the perpendicular direction relative the centre plane in which the beam line lies. Each of the said plates has first electrode terminals across which corresponding potential values are applied and which generate at least part of the said at least one field. The boundary of the end field lies on each end of the said at least one section and said first electrode terminals are essentially thin and flat.
EFFECT: possibility of using the device when analysing an electron beam or when analysing aerosol transportation.
