Early in 2008 an expert meeting [1] on model codes for spallation reactions had been organized by IAEA and ICTP. The experts had discussed in depth the physics bases and ingredients of the different models and the available experimental data as well. Since it is of great importance to validate on selected data the abilities of the various codes to predict reliably the different quantities relevant for applications, it has been agreed to organize an international benchmark of the different models developed by different groups in the world.
This benchmark is organized under the auspices of IAEA and the analysis of the results is done with the help of an International Advisory Board. Necessary tools have been developed to do a comparative study of the calculated and experimental data. Preliminary results have been obtained from the comparison of different models with experimental data to better understand the physical basis, approximations, strengths and weaknesses of the currently used spallation models and codes.
