Experimental studies of prompt fission neutron energy spectra
Paper in proceedings, 2013
Prompt fission neutron spectra were measured in the reactions 238U(n, f), 235U(n, f) and 237Np(n, f) at different incident neutron energies. The neutrons were detected using a coaxial doped p-terphenyl scintillation detector in coincidence with fission fragments and their time-of-flight was recorded. The properties of the neutron detector were determined and the results are presented in this work. A preliminary neutron detection efficiency was applied to data from the neutron-induced fission of 238U at En = 5.2 MeV, leading to encouraging results.
