[en] The neutron energy spectrum of the Coupled Fast Reactivity Measurements Facility (CFRMF) has been measured by the ⁶Li(n,α)t spectrometry technique between the energies of 10 keV and 8 MeV. These measurements were made in order to improve the knowledge of this benchmark neutron field as related to dosimetry and other integral cross sections. Energy spectra of both the α⁺t and t responses were obtained simultaneously using two-parameter multichannel pulse height analyses. Spectrometers of different design and resolution characteristics were applied. The data were reduced using recently evaluated cross section information. The results are compared with the neutron spectrum calculated using recently evaluated cross section information
