Kurzbeschreibung (Abstract)
Measurements have been carried out on neutron yields and spatial distributions in U/Pb, Pb and Hg thick targets and the surrounding paraffin moderators bombarded by 0.533 and View the MathML source protons. CR-39 detectors were deployed on the surfaces of targets and moderators to record the neutrons produced in the targets. The measurements show that:
(1) Neutron yield of Hg target is less than U/Pb and Pb targets on bombardment by protons. Neutron yield ratio of U/Pb and Pb to Hg target are 2.01±0.10 and 1.76±0.33, respectively. This means that Hg target is less preferable in order to get more secondary neutrons.
(2) Neutron yields along View the MathML source thick targets decrease approximately linearly with the thickness through which the incident protons have penetrated. The lower the incident energy, the steeper the decrease of neutron yield.
(3) Secondary neutron spectra for different incident energies are close to each other, while some differences have been observed.
