Abstract (AI)
Measurement of the neutron yield is performed at a primary energy of 400MeV/u carbons for the Pb target. Water-bath activation-foil method is used in a moderation measurement with Au foils to detect the moderated neutrons. The neutron yield is determined to be 18.4±2.1 per carbon by integrating the neutron flux over the entire water volume. The corresponding simulation values are performed by Geant4 code with three models to compare with the experimental results. The comparison shows that the calculated result with the INCL model is in good agreement with the experimental data.
Key Findings
1
Geant4 simulations with three different models were performed to compare with experimental results.
2
Neutron yield from a thick lead target bombarded by 400 MeV/u carbon ions is measured as 18.4 ± 2.1 neutrons per incident carbon ion.
3
Neutron yield measurement used a water-bath activation-foil moderation technique with gold (Au) foils to detect moderated neutrons.
4
The Geant4 INCL model's calculated neutron yield agrees well with the experimental measurement.
