      abstract     = {Materials which are exposed to a radiation field with
                      particles of sufficient high kinetic energies suffer
                      degradation processes and undergo changes in their micro-
                      and macroscopic properties such as mechanical, thermal or
                      electrical ones. The understanding of these radiation
                      induced material damages is crucial both for the estimation
                      of a target's lifetime as well as for safety aspects. This
                      presentation aims to give a compact and clear overview about
                      the current status of the radiation damage analysis of the
                      tantalum target designated for the Jülich high-brilliance
                      neutron source (HBS) based on the common displacements per
                      atom (dpa) concept. After some few fundamental aspects in
                      the very early beginning, the obtained results of SRIM and
                      FLUKA simulations will be presented in a very concise and
                      clear manner. Whereas previous SRIM simulations focus only
                      on the proton damage, FLUKA simulations will mainly set the
                      focus on the damage caused by the produced neutrons but also
                      give a short overview about the contribution of all relevant
                      particles during the hadronic collision cascade.
                      Furthermore, the results of both Monte Carlo codes will be
                      compared to each other and the meaning of the obtained dpa
                      values will be discussed as well as a prospect for future
                      work will be given.},
