“…1 shows neutron energy distribution and energy spectrum of recoil nuclei in the Ti-alloy target generated by undulator photons (see Table 1). Following the approach used in [5] the calculations of diplacements in the target material have been performed seperately for damage induced by neutrons, ions and recoil nuclei. For estimations of displacements induced by neutrons the energy dependent displacement cross-sections from SPECTER code have been used [6].…”

The radiation damage of the positron source target for the International Linear Collider (ILC) has been studied. The displacement damage in target material due to multi-MeV photons has been calculated by combining FLUKA simulations for secondary particle production, SPECTER data for neutron displacement cross-sections and the Lindhard model for estimations of displacement damage by ions. The radiation damage of a stationary Ti6Al4V target in units of displacements per atom (dpa) has been estimated for photons from an undulator with strength 0.92 and period 1.15 cm. The calculated damage is 7 dpa. Approximately 12.5% of displacement damage result from neutrons.
