A variant of the target unit based on tungsten rods cooled by molten-salt coolant (alkali-metal fluorides) in a subcritical electronuclear facility is examined. The results of calculations of its main parameters are presented: the neutron yield, neutron spectrum on the lateral surface, top and bottom ends of the target, total energy release, specific energy release and induced activity. The calculations...
The results of an experimental determination and computational modeling of the rates of threshold reactions on 209Bi, Pb, 197Au, 181Ta, 169Tm, In, 93Nb, 65Cu, 63Cu, 64Zn, 59Co, 27Al, 19F, and C on the external surface of and inside a thick lead target irradiated by 0.8 GeV protons are presented. The reaction rates were measured by γ spectrometry using Ge and (Ge–Li) detectors with resolution 1.8 and...
The work is aimed at experimental determination of the independent and cumulative yields of radioactive residual nuclei produced in intermediate-energy proton-irradiated thin targets made of highly isotopic enriched and natural lead (206,207,208,natPb) and 209Bi. 5972 radioactive product nuclide yields have been measured in 55 thin targets induced by 0.04, 0.07, 0.10, 0.15, 0.25, 0.6, 0.8, 1.2, 1...
