Experimental studies of prompt fission neutron energy spectra
Paper i proceeding, 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.
