Description	Journal: Journal of Physics: Conference Series The proposed High Brilliance Neutron Source (HBS), recognized within the Helmholtz Association of German Research Centres, will optimize the entire chain from particle source through particle accelerator, target, moderator, reflector, shielding, beam extraction, beam transport all the way to the detector, utilizing the nuclear Be(p,n) or Be(d,n) reaction in the lower MeV energy range. A $D_{2}$O moderating reflector prototype (MRP) and a cold source were constructed and build according to MCNP parameter studies. The MRP was tested in a feasibility study at the TREFF instrument at MLZ (Garching). Cold beam extraction from the flux maximum within the moderator based on liquid para $H_{2}$ and other cold moderators will be tested by energy spectroscopy via TOF-method. Different ratios of liquid ortho/para $H_{2}$ will be fed to the cold moderator. The ratio will be controlled by feeding from reservoires of natural liquid $H_{2}$ and a storage loop with an ortho/para converter and determined via online heat capacity measurement.
