      abstract     = {In recent years, the development of high-current
                      accelerator-based neutron sources (HiCANS) has gained in
                      interest to propose a novel option for the next generation
                      of neutron sources. In HiCANS high neutron yields are
                      achieved by irradiating metal targets with proton beams with
                      energies in the MeV range bellow the spallation threshold
                      and currents of several tens of milliamps. Based on this
                      concept, the High Brilliance neutron Source (HBS) project
                      was developed at Forschungszentrum Jülich to deliver a high
                      flux of neutrons to various scattering, analytics and
                      imaging instruments.Relying on the experience and challenges
                      of assembling the HBS shielding prototype at
                      Forschungszentrum Jülich, the HBS target station shielding
                      was developed from several layers of lead and borated
                      polyethylene with a suitable stepped support structure. The
                      aim of the shielding is to keep the dose rate in the
                      monitored area well below the radiation protection criteria.
                      The entire target station is modelled for particle transport
                      simulation on the basis of the mechanical design. The dose
                      rate distribution inside the target station as well as on
                      the outside of the bunker walls is calculated during beam
                      operation and also when the beam is switched off. The
                      analysis of neutron and gamma flux and dose rate
                      distribution in the target station from the radiation
                      protection aspects will be presented.This work is part of
                      the collaboration within ELENA and LENS on the development
                      of HiCANS.},
