      abstract     = {With 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.},
