“…However the difference in the response of each de tector when the SNM or the 252 Cf is either bare or shielded with lead and polyethylene (which is a hydrogenous material) can be seen in Tables 5 and 6 The detectors have a minor efficiency when the material is shielded. In this case, the detection can be done with the PVT de tectors too, due the γ gamma ray produced during the neutron interaction with the polyethylene, like 2.2 MeV induced during the neutron capture in hydrogen (Vega Carrillo et al, 2013).…”

“…[7][8][9] In this investigation, new shielding material is designed by genetic algorithm (GA) combined with Monte Carlo N-Particle Code (MCNP) against the neutron and γ ray spectrums in the inner surface of the shield for CANS. Many blocks of new shielding material were manufactured, and the attenuation detection experiments were carried out on RANS.…”

The Compact Accelerator-driven Neutron Source (CANS), especially the transportable neutron source is longing for high effectiveness shielding material. For this reason, new shielding material is researched in this investigation. The component of shielding material is designed and many samples are manufactured. Then the attenuation detection experiments were carried out. In the detections, the dead time of the detector appeases when the proton beam is too strong. To grasp the linear range and nonlinear range of the detector, two currents of proton are employed in Pb attenuation detections. The transmission ratio of new shielding material, polyethylene (PE), PE + Pb, BPE + Pb is detected under suitable current of proton. Since the results of experimental neutrons and γ-rays appear as together, the MCNP and PHITS simulations are applied to assisting the analysis. The new shielding material could reduce of the weight and volume compared with BPE + Pb and PE + Pb.
