Abstract
A description of the setup and methodology for conducting activation benchmark experiments for measuring spectral indices is given. The neutron generator NG-24M was used as a fusion neutrons source, which emits neutrons with an energy of ~14.1 MeV, and samples with a known isotopic and chemical composition were used as experimental samples. Measerenents of products (n, n), (n, p), (n, pn), (n, α), (n, n'γ) and (n γ) reactions was carried out using two γ-spectrometers based on coaxial HP detectors of the GC2518 type and one planar detector GUL 0110 type. A spectrometer with a LaBr3(Ce) scintillator was used to measure short-lived reaction products. The absolute detection efficiency of the spectrometers was determined using exemplary spectrometric gamma sources certified by VNIIM named D.I. Mendeleev. The procedure for measuring irradiated samples is fully automated using the developed sample changers USO-45 and USO-48. The γ-spectra were processed using the GENIE2000 software. The SIGMA code was used to accumulate and store primary information, identify the resulting radioactive products, and calculate independent and/or cumulative reaction rates. The dimensions and composition of the materials of the installation elements are presented, which are necessary to create a mathematical model used for transport simulation.
