“…The emission of secondary neutrons and gammas in the beryllium slab, to be used as primay particles in GEANT4, was simulated according to the experimental thick target data published by Brede et al 14) In that work, the beam energy ranged from 9. The emission of secondary gammas in the 9 Be slab was directly simulated with GEANT4, since to our knowledge there are no experimental data of gamma emission in these conditions.…”

“…28) Hadronic interactions were modelled with the QGSP_BIC_HP physics list, which uses the Binary cascade model implemented in GEANT4 for the transport of protons, neutrons and ions with energies below ∼10 GeV. 14) used to estimate the emission in the 9 Be slab are also plotted. range covered in this work, the high precision (HP) package (which uses G4ENDL data library, mainly based on ENDF/B, 29) JEFF 30) and JENDL 31) evaluated nuclear data) is used instead.…”

“…These models are found unreliable in predicting neutrons and photons generated by low energy protons and deuterons. In order to overcome this problem, secondary neutron beams from proton/deuteron 9 Be source have been generated following the experimental thick target data published by Brede et al 14) However, the production of gammas in the 9 Be source has been simulated with the GEANT4 toolkit due to the abscence, to our knowledge, of experimental data.…”

This work presents a GEANT4 application (version 9.3.p01) for the calculation of gamma/neutron dose on a AMISC5 flip-flop target from a proton/deuteron 9 Be neutron source. For comparison purposes, a gamma irradiation campaign using a 60 Co standard irradiation source was also simulated. In all cases we consider energy rate per unit volume for comparison in future experiments in order to establish differences between radiation effects on electronics due to neutron/gamma and pure gamma beams.

“…Meadows measured neutron spectra and yields at 0 o for deuterons with energies between 2.6 MeV and 7.0 MeV bombarding a thick beryllium target [11]. Neutron spectra and yields for higher neutron energies have been measured [12][13][14], and the fast neutron radiography has been carried out with the Be(d, n) reaction at PTB with a deuteron energy of 13 MeV [6].…”

The D-Be reaction was investigated with a 4.5 MV Van de Graaff accelerator and a 600 kV Cockcroft-Walton accelerator. Fast neutron yields were measured for deuteron beams with energy from 200 keV to 3 MeV bombarding a thick beryllium target. Also angular distributions for emitted neutrons were measured at several deuteron energies. Fast neutron radiography was carried out with simple samples at the 4.5 MV Van de Graaff accelerator. The preliminary experiment results indicate that the D-Be reaction at lower deuteron energies can be used for fast neutron radiography, if the gamma rays are sufficiently shielded.

Accelerator-based neutron sources are an attractive alternative to nuclear reactors for providing epithermal neutron beams for Boron Neutron Capture Therapy. Based on clinical requirements and neutronics modeling the use of proton and deuteron induced reactions in 7 Li and 9 Be targets has been compared. Excellent epithermal neutron beams can be produced via the 7 Li(p,n) 7 Be reaction at proton energies of ~2.5 MeV. An electrostatic quadrupole accelerator and a lithium target, which can deliver and handle 2.5 MeV protons at beam currents up to 50 mA, are under development for an accelerator-based
