Abstract: Neutrons can be produced by fission in nuclear reactors, by spallation using high-power proton accelerators, and by nuclear reactions with low-energy proton accelerators. While the first two techni¬ques can offer the highest neutron flux production, current state-of-the-art accelerator technology offers the opportunity for a new landscape of novel and unique high-brilliance neutron sources based on low-energy proton accelerators. The Jülich Centre for Neutron Science has started a project to develop and design compact accelerator driven high-brilliance neutron sources as an efficient and cost effective alternative to current low- and medium-flux reactor and spallation sources. Such compact sources have the potential to offer access of science and industry to neutrons as local national or regional medium-flux, but high-brilliance neutron facilities. The project aims to deliver a “High-Brilliance Neutron Source (HBS)”, where a compact neutron production and moderator system provide thermal and cold neutrons with high brilliance efficiently extracted in an optimized neutron transport system. With shaping the experiment from the source to the detector a holistic neutron experiment could be set-up for the specific scientific requirements in a flexible and efficient way for the neutron user. This presents a particular challenge for the appropriate neutron transport systems to deliver the full brilliance of the source to the sample. Neutron lenses, ballistic guides and focusing systems will be requested to minimize any loss in brilliance and neutron flux. In this report we will present a brief outline of the JCNS HBS project and discuss resulting requirements on neutron transport devices.
