20090166549 | HETEROGENEOUS CAPTURE-GATED NEUTRON SPECTROMETER - A system and method for a heterogeneous capture-gated neutron detector are disclosed. The system includes an organic hydrogenous scintillating layer configured to emit at least one collision photon when contacted with a neutron having an energy greater than a predetermined value. A neutron capture layer is located adjacent the organic scintillating layer and configured to capture the neutron and emit at least one gamma ray. The organic scintillating layer is further configured to emit at least one capture photon in response to the at least one gamma ray from the neutron capture layer. Detection of the collision photon and capture photon designate a detected and captured neutron. | 07-02-2009 |
20090206269 | METHOD FOR DETERMINING THE MATERIAL COMPOSITION OF A MATERIAL SAMPLE - A Method for determining the material composition of a material sample which emits radiation comprises the following method steps: recording a spectrum of the energy deposited in a detector material by the radiation; determining a first energy deposited in a first energy range, a second energy deposited in a second energy range, and a third energy deposited in a third energy range; assigning a first colour parameter to the first deposited energy, a second colour parameter to the second deposited energy, and a third colour parameter to the third deposited energy; and comparing the assigned colour parameters with predetermined values for the colour parameters, the predetermined values typically corresponding to colour parameters of a predetermined material composition. | 08-20-2009 |
20110049380 | Neutron Energy Spectrometer - A neutron spectrometer is disclosed, which consists of a Helium-3 proportional counter connected by cable to signal and data processing circuits, and a series of moderator shells and moderator lids. The series of cylindrical moderator shells are designed to fit within one another, like Russian Matryoshka dolls, with the counter at the center. Small air gaps are introduced between the shells so that removal of one shell from another is facilitated. The counter is placed within the smallest cylindrical moderator shell, and then a circular lid matching the smallest shell is placed on the opening of the first shell to close the first shell. This first closed shell is then placed within a second shell, which shell is closed with its corresponding circular lid. The cable is routed through the series of shells. A method for using the invention is also disclosed, wherein the counter reading is taken from the fully-assembled neutron spectrometer. Then the outer cylindrical shell and circular lid pair is removed, and another measurement of the counter is recorded. This is continued until the last shell is removed, and a measurement is recorded using the bare counter. | 03-03-2011 |
20130214171 | RADIOACTIVITY EVALUATION METHOD AND RADIOACTIVITY EVALUATION SYSTEM - According to an embodiment, a radioactivity evaluation method has: a first input step; a selection step in which the calculating section selects a representative neutron energy spectrum and a representative neutron fluence rate; a second input step; an radioactivity calculating step in which the calculating section calculates quantities of the radioactivity that correspond to the representative neutron energy spectra and the representative neutron fluence rates; a data storing step; a nuclide-by-nuclide radioactivation reaction rate calculating step in which the calculating section calculates a radioactivation reaction rate of each nuclide based on the neutron energy spectra at the position of each of the object sections; an object-by-object adding-up step; a nuclide determining step; and an object position determining step. | 08-22-2013 |
