Recalibration of Some Sealed Fission Chambers - France - in Mark III, Mol, Belgium Facility

The selection of neutron fields allowing the integral neutron data validation as well as the calibration of the instrumentation used in the absolute measurements, was a continuous task of the experts in the area. The choosing of the neutron spectrum is based on the hypothesis of correct description of the spectral shape by calculation methods as well as integral and differential measurements. Several standards were proposed to cover the energy range between 0 and 18 MeV...
