Real-time correction of chance coincidence losses in high-rate Compton suppression spectrometry

Chance coincidence losses in a Compton suppression spectrometer are instrumentally corrected by comparing the chance coincidence rate to the counting rate of the Germanium detector. The normally not observable chance coincidence rate is reconstructed from the rates of Germanium detector and scintillation detector in any auxiliary coincidence unit, after the destruction of true coincidence by sufficiently delaying one of the coincidence partners.
