Reliability and use of INCL4.6-Abla07 spallation model in the frame of European Spallation Source target design
Résumé
In the framework of the European Spallation Source (ESS) project, works on ESS target design need
computational tools and the validation of these tools must be done to estimate accuracy of the calculation
results. INCL4.6 and Abla07 have been implemented in a beta version of MCNPX2.7 to be able to use them
when transport is needed as ESS spallation target design. Within ESS project, we decided to benchmark our
spallation model on excitation functions (p+W) to assess the reliability on a thin target according to the
produced isotope and the projectile energy. We focused on a list of hazardous nuclei given by previous ESS
calculations and from previous experiments. These results, which can of course help to estimate uncertainties
as designing ESS target, were supplemented by another benchmark done with a thick tungsten target and
giving isotope production along the beam axis and radially as well.
