      abstract     = {The High Brilliance Neutron Source (HBS) project was
                      initiated at the Jülich Centre for Neutron Science of the
                      Forschungszentrum Jülich (JCNS). It aims to develop a
                      medium neutron source facility based on a linear
                      accelerator, scalable up to 70 MeV proton energy and
                      optimized to deliver high brilliance neutron beams to a
                      variety of neutron instruments. To better understand the
                      neutron yield of different materials at different energies
                      of bombarding protons, measurements to determine the
                      proton-induced neutron production were carried out at the
                      accelerator facility Julic-Cyclotron at Forschungszentrum
                      Jülich. The experiment was set up with different targets
                      (e.g. beryllium, vanadium and tantalum), which were
                      surrounded by a polyethylene moderator. The neutron yield
                      was indirectly determined by measuring the gamma radiation
                      induced by thermal neutron capture in the moderator. The
                      calibration was performed with an Am-Be neutron source to
                      obtain the neutron gamma conversion rate. Corrections were
                      made for escaping neutrons with the parameter of neutron
                      escape ratio, which was calculated from Monte Carlo
                      simulations. The details of the simulations will be
                      introduced at the workshop. The total neutron production
                      compared with measurements, the neutron and gamma escape
                      ratio and the spectrum as well as the neutron flux
                      distribution will also be presented.},
