Experimental Studies on Particle and Radionuclide Production Cross Sections for Tens of MeV Neutrons and Protons

“…Past experiments on Li were discrepant markedly [14] and new high quality data were required for practical database and also for model refinement of neutron spectrum.

Fast neutron and proton therapy sources

“…These measurements were made at 16, 33 and 50 MeV using the TOF technique. Saltmarsh et al [88] also made spectral angular distribution measurements for E d = 40 MeV on thick beryllium targets. The main features of these spectra were consistent with the measurements of Meulders et al [87].…”

“…Christenson et al [95] calculated the neutron intensities for the thick-target d + Be reaction both on-and off-axis for deuteron energies between 14 and 40 MeV. The agreement between the theoretical predictions and experimental data [87,88,[99][100][101] is rather poor at low deuteron energies but improves with increasing deuteron energy. The intensities were derived by integrating the spectra above the detection threshold and the disagreement can therefore probably be ascribed to the different detector thresholds used as the effect of varying thresholds is accentuated at low energies.…”

Modelling and analysis of nucleon emission from deuteron-induced reactions at incident energies up to 100 MeV

“…is considered as a promising reaction to generate intensive neutron beams. Fig.1 shows experimental thick target neutron yields (TTNYs) from (p,xn) and (d,xn) reactions on 9 Be [1,2]. This figure shows some advantages of a (d,xn) neutron source over a widely-used (p,xn) neutron source.…”
