Layout diagram of integral experiment with natPb samples

Caption

The figure illustrates the experimental setup used to measure neutron leakage spectra from natural lead (natPb) slab samples, employing both D-T and D-D neutron sources at the integral experiment platform of the China Institute of Atomic Energy (CIAE). The pulsed neutron beam irradiates the natPb samples placed at different thicknesses (5 cm, 10 cm, and 15 cm), while neutron detectors are positioned at 60° and 120° to record the angular distributions of emitted neutrons using the time-of-flight (TOF) technique. The system incorporates a collimated beamline and heavy shielding to suppress background scattering and improve signal clarity. This layout enables high-precision measurement of neutron transport properties, supporting the benchmarking of evaluated nuclear data libraries critical for nuclear reactor design, fusion technology, and radiation shielding.
