摘要：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.
