    摘要: This detector comprises electron multiplication means (14) producing a cluster of electrons under the impact of each particle (2), a layer (6) that this cluster passes through, and which emits a light pulse by interaction with the layer, and transparent electron detection means (8) capable of determining the moment of impact of the particle and supplying information about the impact positions for each moment thus determined, so that these positions can be determined and correlated with the moments determined by the detection means.

    摘要: The present invention concerns the enhancing of the mass resolution of wide angle tomographic atom probes. The invention consists of an atom probe also comprising a sample-holding device and a detector which are separated from one another by a distance L and enclosed in a chamber, an “Einzel” type electrostatic lens consisting of three electrodes arranged inside the chamber between the sample and the detector, to which electrical potentials are applied so as to form an electrical field that strongly focuses the beam of ions emitted by the sample under test when the probe is operating. According to the invention, the geometry of the electrodes is defined precisely so as to greatly limit the effects of the spherical aberration that affects the “Einzel” lens on the beam of ions, said spherical aberration being clearly sensitive when the lens is greatly polarized. The invention applies more particularly to the atom probes known as 3D atom probes.
