      abstract     = {The advent of high-current accelerator systems launched the
                      development of high-current accelerator-driven neutron
                      sources (Hi-CANS) utilizing low energy nuclear reactions.
                      These facilities are intended to bridge the gap between the
                      high-power spallation sources and the low power CANS. They
                      are designed to maximize beam brightness and to offer
                      performance of their beamline instrumentation highly
                      competitive with existing research reactors. Within the
                      framework of the Jülich High Brilliance Neutron Source
                      (HBS) project, a HiCANS is developed. One of the key
                      components as well as the main power-limiting factor is the
                      target that releases neutrons from the impinging protons via
                      nuclear reactions. Since the neutron yield of nuclear
                      reactions is quite small, this is compensated with a high
                      proton current. However, the high proton current leads to a
                      strong heat release inside the target. At the same time the
                      target has to be very compact to allow the subsequent
                      extraction of a neutron beam with a high brilliance.
                      Overall, this leads to unique requirements, such as those
                      for the HBS target given by a 70 MeV pulsed proton beam with
                      a peak current of 100 mA and an average thermal power
                      release of 100 kW inside the target with a surface area of
                      100 cm². The talk will highlight the technical challenges
                      involved in designing this new type of HiCANS target.
                      Starting with the choice of materials, it will cover topics
                      such as heat dissipation, radiation damage, and handling an
                      activated target, as well as the difficulties involved in
                      properly testing such a target.},
