OBTAINING INELASTIC SPECTRA FREE OF DETECTOR BORN GAMMA RAYS INDUCED BY NEUTRONS

摘要

In an embodiment, a method includes receiving a first measurement (610) of gamma rays via a detector (204) during a first period of time, receiving a second measurement (602) of gamma rays via the detector (204) during a second period of time, removing the second measurement (602) from the first measurement (610) to produce an inelastic spectrum, determining a spectral slope (1204) from the inelastic spectrum, determining a scaling factor (1202) based on the spectral slope (1204), determining a spectral shape associated with the detector (204), determining a detector-induced spectrum (606, 608) by applying the scaling factor (1202) to the spectral shape, and removing the detector-induced spectrum (606, 608) from the inelastic spectrum to produce a clean inelastic spectrum (604).
