  • Patent number: 8212221
    Abstract: The invention relates to a detector for measuring nuclear radiation, especially gamma-radiation, comprising a scintillator crystal with a light decay time of less than 100 ns, a silicon drift detector (SDD) for the measurement of both direct hits of low energy radiation and the light, being emitted from the scintillator crystal, the silicon drift detector being mounted between the scintillation crystal and the radiation entry window, a preamplifier, connected to the SDD, electronic devices, being capable of determining the signal rise time of the measured signals and of separating the signals on the basis of said rise time, electronic devices, being capable of separately collecting the energy spectra of SDD and scintillator detection events on the basis of the different rise times.

  • Patent number: 8158449
    Abstract: A structure and a method for operating the same. The method includes providing a detecting structure which includes N detectors. N is a positive integer. A fabrication step is simultaneously performed on the detecting structure and M product structures in a fabrication tool resulting in a particle-emitting layer on the detecting structure. The detecting structure is different than the M product structures. The M product structures are identical. M is a positive integer. An impact of emitting particles from the particle-emitting layer on the detecting structure is analyzed after said performing is performed.

  • Publication number: 20090039270
    Abstract: A method and detector for detecting particle emissions from a test sample includes positioning a detector over the test sample, wherein the detector includes a plurality of detection units, wherein each detection unit includes a first silicon detector and a barrier layer removably disposed over the first silicon detector. The method includes generating a first current signal in the silicon detector in response to receiving a first particle emitted from an atom of the test sample by the silicon detector of the first detection unit, and responsive to a recoiling daughter nuclide of the atom striking the barrier layer of the first detection unit, the recoiling daughter nuclide resulting from emission of the first particle from the atom, absorbing the recoiling daughter nuclide by the barrier layer of the first detection unit.
