| Abstract |
Neutron detection traditionally takes place with detectors based upon particle detection technologies like gas or scintillation detections. These detectors have a high dynamic range, and are very performing at low counting rates and fast timing (time of flight) applications. At high counting rates however, continuous imaging detectors such as CCD or CMOS camera's optically linked to scintillators, can have very good performances concerning linearity and spatial resolution but the dynamic range of these systems is limited by noise and gamma background. We explore a technique that allows us to use imaging detectors as counting detectors at lower counting rates, and transits smoothly to continuous imaging at higher rates. Neutron detection involves reactions releasing energies of the order of the MeV, while X-ray detection releases energies of the order of the photon energy, (10 KeV range). This 100-fold higher energy allows the individual neutron detection light signal to be significantly above the noise level, as such allowing for discrimination and individual counting. The theory is next confronted with experimental measurements on CCD and CMOS type commercial cameras.
