Reliability and use of INCL4.6-Abla07 spallation model in the frame of European Spallation Source target design

International audienceIn the framework of the European Spallation Source (ESS) project, works on ESS target design needcomputational tools and the validation of these tools must be done to estimate accuracy of the calculationresults. INCL4.6 and Abla07 have been implemented in a beta version of MCNPX2.7 to be able to use themwhen transport is needed as ESS spallation target design. Within ESS project, we decided to benchmark ourspallation model on excitation functions (p+W) to assess the reliability on a thin target according to theproduced isotope and the projectile energy. We focused on a list of hazardous nuclei given by previous ESScalculations and from previous experiments. These results, which can of course help to estimate uncertaintiesas designing ESS target, were supplemented by another benchmark done with a thick tungsten target andgiving isotope production along the beam axis and radially as well
