[en] At the Paul Scherrer Institut, several experiments have been conducted for studying radiation damage effects induced by high energy protons and spallation neutrons. The materials for these investigations were irradiated in the targets of the Swiss spallation neutron source (SINQ): this SINQ target irradiation program (STIP) has been run since 1998 within a broad international collaboration with Ecole Polytechnique Federal de Lausanne (EPFL), Forschungszentrum Juelich (FZJ), Oak Ridge National Laboratory (ORNL), Commissariat a L'energie Atomique Centre D'etudes de Saclay (CEA), Japan Atomic Energy Agency (JAEA), Los Alamos National Laboratory (LANL), and University California Santa Barbara (UCSB). In several consecutive campaigns, more than 40 kinds of materials, mainly austenitic or ferritic/martensitic (FM) steels, were irradiated to doses up to 20 dpa and 1800 appm He in a temperature range of 80 to 600 deg. C). As well, experiments have been performed to investigate liquid lead-bismuth eutectic (LBE) corrosion and embrittlement effects on T91 steel under irradiation with 72 MeV protons. In this presentation, an overview will be given showing a selection of results from these experiments, which include the mechanical properties and microstructure of FM steels like T91, F82H, Optifer, and austenitic steels like EC316LN, SS 316L.
