| Popis: | The results of measurements of the γ-ray and neutron leakage spectra from three vanadium spheres with diameter 10, 24 and 34 cm at their internal irradiation by 14-MeV neutrons are presented. The experiments are carried out in the framework of ISTC Project #910 in collaboration with FZK. All the spheres have the same geometry of the central hole 3 cm in diameter. The measurements were carried out by the time-of-flight technique. NaI(Tl) crystal with the dimensions of ∅150×100 mm was used as γ-spectrometer. The neutron leakage spectra were measured with two types of scintillation detector, and by a gas proportional counter at a stationary mode of neutron generator operation. |
