Abstract.We have so far developed a computational code system dedicated to deuteroninduced reactions in combination with some theoretical models. In our previous works, the code system was successfully applied to systematic analyses of double-differential cross sections (DDXs) of (d,xp) reactions for 12 C, 27 Al, and 58 Ni at incident energies up to 100 MeV.In the present work, we apply the code system to neutron emission from deuteron-induced reactions. Since there is few experimental data of DDXs of (d,xn) reactions, double-differential thick target neutron yields (TTNYs) are calculated and compared with experimental data instead of DDXs. The calculation using the code system reproduces the measured TTNYs for carbon at incident energies up to 50 MeV.

“…Emitted neutrons from the reaction peak at forward angles with respect to the deuteron beam direction, and have an energy spectrum with a most probable energy of 14 MeV, as given in Ref. 24. In evaluating the 99 Mo yield using the neutrons, we showed that a proper shape of a 100 Mo sample to obtain 99 Mo with good specific activity is a cylindrical one.…”

Generation of Radioisotopes with Accelerator Neutrons by Deuterons

A new system proposed for the generation of radioisotopes with accelerator neutrons by deuterons (GRAND) is described by mainly discussing the production of 99 Mo used for nuclear medicine diagnosis. A prototype facility of this system consists of a cyclotron to produce intense accelerator neutrons from the nat C(d,n) reaction with 40 MeV 2 mA deuteron beams, and a sublimation system to separate 99m Tc from an irradiated 100 MoO 3 sample. About 8.1 TBq/week of 99 Mo is produced by repeating irradiation on an enriched 100 Mo sample (251 g) with accelerator neutrons for two days three times. It meets about 10% of the 99 Mo demand in Japan. The characteristic feature of the system lies in its capability to reliably produce a wide variety of high-quality, carrier-free, carrier-added radioisotopes with a minimum level of radioactive waste without using uranium. The system is compact in size, and easy to operate; therefore it could be used worldwide to produce radioisotopes for medical, research, and industrial applications.

“…The foils were 2.5*2.5 cm 2 with a thickness of 0.1 cm in order to minimize the attenuation and the diffusion of neutrons. After irradiation of the nat Cu target, the measurement of the resulting activities in the activation foils was used to reconstruct the incident neutron spectra [3,4,5] using an unfolding method.…”

Experimental approach to measure thick target neutron yields induced by heavy ions for shielding

Abstract. Double differential (angular and energy) neutron distributions were measured using an activation foil technique. Reactions were induced by impinging two low-energy heavy-ion beams accelerated with the GANIL CSS1 cyclotron: ( 36 S (12 MeV/u) and 208 Pb (6.25 MeV/u)) onto thick nat Cu targets. Results have been compared to Monte-Carlo calculations from two codes (PHITS and FLUKA) for the purpose of benchmarking radiation protection and shielding requirements. This comparison suggests a disagreement between calculations and experiment, particularly for high-energy neutrons.
