摘要：

For characterization and calibration of neutron dosimeters acid spectrometers, monoenergetic neutron calibration fields have been developed at eight energy points between 8 keV and 15 MeV (8 and 27 keV, 0.25, 0.55, 1.0, 2.0, 5.0 and 15 MeV). Monoenergetic neutrons are obtained by the Sc(p, n) reactions for 8 and 27 keV, and by the Li-7(p, n), T(p, n), D(d, n) and T(d, n) reactions between 0.25 and 15 MeV. Care was taken to reduce background neutrons by parasitic reactions and the scattering of primary neutrons at the target. The neutron spectrum was characterized by the time-of-flight technique, acid the neutron fluence was measured with two independent methods within +/-5%. The field has been applied successfully for calibration and characterization of various neutron dosimeters and spectometers.
