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

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.
