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.},
