| 520 | _ | _ | |a In the framework of the development of the HBS HiCANS project in Jülich, the World's first 1-dimensional cryogenic moderator based on liquid para-hydrogen has been designed, constructed and tested. Para-hydrogen is a special form of hydrogen as the mean free paths for thermal and cold neutrons differ by about 1 order of magnitude. This makes it possible to develop a 1-dimensional cold moderator where the extraction happens along the extended dimension while the feeding with thermal neutrons is done along the other two dimensions, which are small in comparison.The moderator cryostat was designed such that the hydrogen volume is completely enclosed and where hydrogen serves as coolant as well as moderator material. The heat is removed by a closed-cycle cryocooler outside the target-moderator shielding and the hydrogen is circulated by a pump for cryogenic fluids. This system has been built to fit into a beamport plug of the JULIC Neutron Platform, the technology demonstrator of the HBS project in Jülich. The system successfully was brought into operation and we measured the neutron spectrum emitted from this cold source. Finally, the measurements and simulations of the neutron moderation were compared to assess the reliability of the simulation tools to be able to describe future moderator setups properly. |
