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.},
