Abstract: This abstract presents the results obtained by the High Brilliance Neutron Source (HBS) project at Forschungszentrum Jülich on the use of ethane as a neutron moderator material. The aim of the study was to conduct a detailed investigation on the behaviour of ethane as a cold moderator for neutrons and assess its performance at different cryogenic temperatures. The experimental measurements were carried out at temperatures of 170 K, 135 K, 100 K, 70 K, 50 K, 25 K, 15 K, and 10 K. The experimental data obtained from the measurements were then analysed and compared with simulation results using the PHITS (Particle and Heavy Ion Transport code System) code. A special phase analysis focusing on ethane's metastable phase was thoroughly analyzed and discussed which allowed for a comprehensive evaluation of the moderator's behaviour and its suitability for neutron moderation. The results showed that ethane exhibited notable changes in its response as the temperature changes. The findings from this study will contribute to the development of advanced neutron compact moderators and provide valuable information for optimizing neutron-based experiments and research facilities.
