The p(20)+Be reaction as a source of fusion relevant neutrons

Popis výsledku v původním jazyce

The p(20)+Be neutron source reaction was investigated at the Nuclear Physics Institute of the Czech Academy of Sciences using the 20 MeV proton beam on thick beryllium target (thickness of 8 mm). Neutron field in close source-to-sample distances was determined by means of the activation foils technique. Set of ten activation foils (Al, Ti, Co, Fe, Ni, Y, In, Nb, Lu, Au) was utilized. Neutron spectrum reconstruction from reaction rates obtained using the gamma-spectroscopy method (semiconductor HPGe detectors) was performed utilizing the modified version of SAND-II unfolding code and relevant activation cross-sections from the EAF-2010 nuclear database. Determined neutron energy spectra were validated against the MCNPX calculations. Developed p(20)+Be neutron field with broad spectrum represents a useful tool for the cross-section data validation within the ITER and IFMIF-DONES research programs (> 12 MeV), neutron-hardness tests of microelectronics, study of material damage, and calibration of new detection systems.
