A SPECTROMETER FOR DOUBLE DIFFERENTIAL NEUTRON EMISSION CROSS SECTION MEASUREMENTS IN THE ENERGY RANGE 1.6 TO 16 MEV
A neutron spectrometer for the measurement of double-differential neutron-emission cross sections has been set up. An electron linac (GELINA) is used as a pulsed white neutron source. The energy of the incident neutrons is determined by the time-of-flight method. The secondary neutron spectra are determined by unfolding the pulse- height distributions observed in eight NE213- scintillators surrounding the sample. The measured spectra are normalised to the shape of the incident neutron flux measured with a "235"**-fission chamber, and afterwards converted to absolute cross sections using as standard the carbon differential elastic scattering cross section below 2 MeV.
