“…The response of moderating spheres decreases when the neutron energy increases beyond 20 MeV, and the energy dependence is rather similar for com monly used spheres [13]. The spectral fluence of high-energy neutrons can, therefore, be determined only by means of a BSS if a priori reliable information is available, at least on the shape of the spectrum, e.g.…”

“…This system consists of a 3 He proportional counter and a set of 11 polyethylene spheres with diameters ranging from 5 to 38 cm (4) . For high-energy neutrons, it was supplemented with 209 Bi and 232 Th ®ssion track detectors (5) .…”

“…et al, 1992;Wiegel et al, 1994) which were adjusted to fit the experimental data. For energies between 20 MeV and about 300 MeV, experimental data for 55 MeV quasi-monoenergetic neutrons (Alevra and Schrewe, 1997) were combined with calculated responses (Aroua et al, 1992). Finally, the data were supplemented up to 1 GeV using empincal extrapolations.…”
