“…Figure 2 shows a close-up of the high energy continuum region. The present results are compared with previous measurements [9][10][11][12][13] and evaluations of JENDL-4.0 and ENDF/B-VII.1 [14]. The ENDF/B-VII.1 evaluation is closer to the present data than the JENDL-4.0 evaluation.…”

Since the discovery of the neutron in 1934 neutron beams have been used in a very broad range of applications, As an aging fleet of nuclear reactor sources is retired the use of compact accelerator-driven neutron sources (CANS) are becoming more prevalent. CANS are playing a significant and expanding role in research and development in science and engineering, as well as in education and training. In the realm of multidisciplinary applications, CANS offer opportunities over a wide range of technical utilization, from interrogation of civil structures to medical therapy to cultural heritage study. This paper aims to provide the first comprehensive overview of the history, current status of operation, and ongoing development of CANS worldwide. The basic physics and engineering regarding neutron production by accelerators, target-moderator systems, and beam line instrumentation are introduced, followed by an extensive discussion of various evolving applications currently exploited at CANS.

Neutron nuclear data of 99 Tc was evaluated, considering cross-sections and spectra provided from recent experiments. The evaluation was made in the incident neutron energy range from 1 keV to 20 MeV, using the optical model and nuclear reaction models. The optical model calculation based on the coupledchannels method was performed for the interaction of neutrons with 99 Tc, and potential parameters appropriately chosen reasonably explain the measured data of total cross-section. The cross-section of inelastic scattering, capture, (n, 2n), (n, p), (n, a) and (n, n 0 a) reactions, and g-ray emission spectra were calculated on the basis of statistical model with preequilibrium and direct components, and they were compared with available experimental data. It is found that the presently evaluated cross-sections and g-ray emission spectra well reproduce those experimental values and that there is a large discrepancy among the present result and evaluated data for neutron emission spectra. The obtained capture crosssection increases at the energies below 1 MeV, relative to that in JENDL-4.0. This makes the transmutation efficiency of 99 Tc into stable 100 Ru by accelerator driven system enhanced. The production cross-section of 99 Mo important for the medical use of nuclear diagnostics reduces by 5-30% at the energies above 12 MeV, compared with JENDL-4.0.
