Abstract

The Swiss spallation neutron source SINQ operated at the Paul Scherrer Institut is driven by PSI's 590 MeV proton accelerator at a beam power of 0.8 MW, as such being the most powerful (CW) spallation source worldwide. The core element of such a facility is the neutron production target. Since the commissioning in 1997, PSI has always fostered combined efforts in the development of the spallation target, including dedicated materials research for high dose radiation environments. The overall goal was to achieve optimized neutron production, combined with sufficient robustness, thermo-mechanical stability and radiation resistance to withstand the severe loads of high-dose irradiation and frequent thermal cycling over an acceptable lifetime. The target itself has been improved in several steps by searching for the optimal materials and geometries. In parallel, numerous experiments have been conducted in the targets of SINQ for studying radiation damage effects induced by high energy protons and spallation neutrons.

Keywords: Spallation target; Spallation materials; Radiation damage; STIP program
