Abstract: The electron beam (28) focussing method has an electron source (16) with the beam displaced from the propagation axis (Z). An electrical acceleration field is created along the axis. A magnetic field (B) is created along the propagation axis and cooperates with the electrical field to create a desired focussing point using the equipotential plane (48,50).

Abstract: A particle-beam column comprising a needle-type ions source (1) such as a liquid metal ion source, one or more round lenses (2), and a plurality of interleaved quadrupole lenses (14, 16). Also an ion-beam column comprising a liquid alloy ion source (1), interleaved quadrupole lenses (14, 16), and a Wien velocity filter (22). Such columns produce a more finely focused beam than columns based only on electrostatic lenses, and allow increased lens apertures and larger beam currents.

Abstract: An electron gun comprising a source (2) with electron-emitting micro-points, an anode (8) spaced apart from the micro-points, a device (16) for applying a high voltage to the anode, and a set (10) of electrodes distributed around the beam from the source to strip focus the beam onto the anode, and acting as an electrostatic shield for shielding the source from the high voltage, said set of electrodes being arranged between the source and the anode and comprising two or more different-sized pairs of electrodes (18a, 18b, 20a, 20b) at positive and negative voltages respectively, their value being such that a weak electrostatic field is generated between the source and the set of electrodes while a strong electrostatic field is generated between the set of electrodes and the anode. The gun further comprises a device for applying medium voltage to the set of electrodes, and a device for applying a suitable voltage to the micro-points.

Abstract: An achromatic magnetic deflection device for deflecting by an angle phi between pi and 2 pi a beam of charged accelerated particles having different momentum. This device comprises an electromagnet provided with pole pieces delimiting three contiguous sectors, the whole of these sectors, having an axis of symmetry XX, presenting flat input E and output S faces and common faces F1 and F2 in an arc of a circle, the position, the radius of curvature of these faces F1, F2 as well as the value of the magnetic induction in the sectors being chosen so that the different paths are substantially orthogonal both to faces F1, F2 and to axis XX.
