  • High resolution particle spectrometer
    Patent number: 4742223
    Abstract: A spectrometer for high-resolution particle energy loss spectroscopy is described. Specifically, the high-resolution particle energy loss spectrometer of the present invention comprises: source means for producing a collimated beam of particles; first stage monochromator means for selecting particles within a specified energy range; intermediate particle lens means for collimating, accelerating and decelerating the particles exiting from the first stage monochromator means; second stage monochromator means for selecting particles within a specified energy range; exit particle focusing means; input particle focusing means; cylindrical analyzer means for selecting particles with a specified energy range; and detector means for detecting impinging particles. The spectrometer described herein obtains higher system resolution at a given output current than other spectrometers known in the art.
    Type: Grant
