Abstract:
Thermal and cold neutrons are an important tool for solid-state physics and engineering investigations. In history, research neutrons have been provided by fission reactors and spallation neutron sources. More and more fission reactors are being shut down due to their age and the provision of new spallation sources is very costly, not only due to the high energy and high current proton accelerator which is necessary.
The Jülich Centre for Neutron Science JCNS has started the HBS project ("High Brilliance neutron Source") to develop a cost-efficient research neutron source based on low energy (some 10 MeV) (p,n) nuclear reactions. Recently, the Technical Design Report for a user facility has been published and a technology demonstrator at low proton intensity has been brought into operation successfully and helped to prove the feasibility and the performance of this kind of facility.
In my talk, I will present the physics behind the HBS neutron source in comparison to the previous approaches and some of the technological innovations necessary to build an efficient research neutron source based on this principle.
