  • Device for measuring the amount of beryllium in a radioactive object
    Patent number: 9915738
    Abstract: A device for measuring an amount of beryllium in a radioactive object, including: a hollow cylinder of a first piece made of a material to thermalize neutrons emitted by the radioactive object and a metal piece to mitigate a dose rate on the radioactive object, the first piece having a hollow cylinder shape deprived of a wall fraction, the metal piece including a solid part inserted in a space which corresponds to the deprived wall fraction of the first piece and a recessed part which is an extension of the solid part and is accommodated within the wall of the first piece, in contact with the first piece; a gamma radiation source accommodated in an indentation of the recessed part of the metal piece; and at least one neutron detector placed in a bulk of the first piece.
    Type: Grant

    Date of Patent: March 13, 2018
    Assignee: COMMISSARIAT A L'ENEGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES
    Inventors: Cedric Carasco, Bertrand Perot, Alain Mariani, Sebastien Colas, Nicolas Saurel

  • Method for determining the spectral and spatial distribution of braking photons, and related device
    Patent number: 8610080
    Abstract: A method for determining the spectral and spatial distribution of a braking photon flow along at least one direction in space (x, y, z), characterized in that the method comprises measuring the neutrons resulting from the impact of the braking photons (ph) on at least one conversion target which is moved in the direction (x, y, z) in space. The invention can be used for X-rays, medical imaging, tomography, etc.
