Measurement and calculation of leakage neutron spectra from beryllium sample using a white neutron field
A leakage neutron spectra measurement has been conducted on beryllium material. The () reaction was employed with carbon ions to produce a white neutron source. Spectra of leakage neutrons passed through a 7 cm thick beryllium slab were measured with a BC-501A liquid scintillation detector by the pulse height discrimination technique and time-of-flight method. The computational analysis of the experiment was performed by GEANT4 Monte Carlo code with INCL, BIC, and BERT physics models. The comparisons between the simulations and the experimental data have shown reasonable agreement.
期刊介绍:
Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
