NIST Calibration of a Neutron Spectrometer ROSPEC

Abstract
A neutron spectrometer, ROSPEC, was acquired for use in the measurement of NIST calibration neutron fields. The spectrometer included options for the measurement of low and high energy neutrons, for a measurement range from thermal neutron up to 16 MeV. The fields used included bare and moderated Cf-252, monoenergetic neutron fields of 2.5 and 14 MeV, and a thermal-neutron beam. Using calibration values determined in this exercise, the spectrometer gives a good approximation of the neutron spectrum, and excellent values for neutron fluence, for all NIST calibration fields. The spectrometer was used to measure an AmBe neutron field in a NIST exposure facility and determined the field quite well. The spectrometer can measure scattering effects in neutron spectra which previously could be determined only by calculation or integral measurements.Citation
