Abstract:
1. A device for online measurement of a flow of fast and epithermal neutrons φ 1 (t n ) at instants t n over an energy interval [E min , E max ], comprising: a fast neutron detector (DNR) containing material suitable for detecting principally fast neutrons; a thermal neutron detector (DNT) containing material suitable for detecting principally thermal neutrons; a first electronic circuit (C a second electronic circuit (C means (PMM, CE) able to determine, at instants t means (PMM, CE) able to determine, at instants t means for computation (CALC), at instants t where KR and KT are, respectively, a coefficient for calibration of the fast neutron detector and a coefficient for calibration of the thermal neutron detector.
