This unique feature makes it possible to design and construct low-dimensional moderators which are elongated along the cold neutron extraction direction(s) but compact along the thermal neutron feeding directions. The small luminous surface together with the directed emission of cold neutrons leads allows to extract cold neutron beams with high brilliance.Here, we will present the concept of low-dimensional moderators as developed within the HBS project for a HiCANS neutron source as well as the experimental realization of a 1-dimensional para-hydrogen cold moderator and first experimental results obtained at the JULIC Neutron Platform.
