Device in which a flux of particles is measured by passing a light beam, with a suitable wavelength, through this flux, giving rise to absorption by the flux of particles. By measuring the intensity of the light beam, the flux of particles is thus measured. A device D1 makes it possible, on the hand, to stop down (set a diaphragm to) the flux of particles and, on the other hand, to focus or collim...
