Abstract
A possible chip-irradiation facility is considered to be built at the European Spallation Source, which will start operation in 2019 and will be the most powerful (5 MW) spallation neutron source in the world. For single-event effects tests, a fast neutron spectrum is needed, to mimic the atmospheric reference spectrum. ESS can offer a convenient facility, by taking a beam line looking down at 27 degree angle with respect to the proton beam line, looking directly to the tungsten target, at a distance of about 10 m from the target. Such location offers unprecedented high neutron flux, crucial for providing an accelerated timeframe for the studies, with a convenient location for a shielded experimental room without negative impact to the instruments hall. Two main aspects have been studied: the fundamental beam characteristics (beam profile and footprint, spectrum) and a first design of the beam dump (geometry, materials and performance).
