000906984 520__ $$aWith the decommissioning of research reactors in Europe and elsewhere in recent years, theavailable capacity on neutrons for science is declining and access is becoming crucial for neutronusers. Responding to this development and to offer an alternative way on new neutron sources,the High Brilliance Neutron Source (HBS) project was initiated at the Jülich Centre for NeutronScience (JCNS) at the Forschungszentrum Jülich. It aims at developing a high-current acceleratordrivenneutron source (Hi-CANS) to deliver high-brilliant neutron beams to a variety of neutronscattering instruments. Within the framework of this project, a compact tantalum neutronproductiontarget with a sophisticated internal microchannel cooling was developed for a 70 MeVproton beam with a peak current of 100 mA and an average power of 100 kW for a target areaof 100 cm². The high-power density requires an optimization of the microchannel coolingstructure to reduce temperatures and to minimize thermo-mechanical stresses, whereas thehigh-current requires a design minimizing proton accumulation within the tantalum target toavoid relevant blistering problems. In order to get such an optimal design, the microchannelgeometry was gradually adapted using the particle transport code FLUKA and thermo-mechanicalsimulations with ANSYS. The details of these investigations and the resulting microchannel targetdesign will be presented.
