      abstract     = {Beams of free neutrons are an important probe to analyze
                      the structure and dynamics of condensed matter and are
                      produced at neutron research reactors, neutron spallation
                      sources or compact accelerator-based neutron sources (CANS).
                      An efficient construction of CANS with a maximized neutron
                      yield and brilliance requires reliable knowledge of the
                      consequences of radiation-induced material damage, the
                      predominating bottleneck of a target’s lifetime. In the
                      framework of the Jülich High-Brilliance neutron Source
                      project, the impact of proton- and neutron-induced material
                      damage of a tantalum target was investigated. The Monte
                      Carlo codes FLUKA and SRIM were utilized to extract the
                      number of displacements per atom resulting from atomic
                      rearrangements. The simulations performed distinctly
                      identify the rear of the neutron target as the most
                      vulnerable area, with the protons as main damage
                      contributors. The minor contribution of neutrons is a
                      material-specific phenomenon due to their high mean free
                      path length in tantalum. Numerical results of the
                      simulations served to calculate average and peak damage
                      rates Rd (dpa/s), both in turn scaled to annual displacement
                      doses for continuous operation in a full power year
                      (dpa/fpy). Supplemented by the literature, a minimum target
                      lifetime τmin of 2.6 years (33 Ah) is concluded.},
