abstract = {The High Brilliance Neutron Source (HBS) is expected to be
the next-generation neutron facility, which uses low proton
energy (70MeV) to achieve high neutron brilliance. As the
moderator-reflector unit is correlated to the neutron
moderation, reflection, and transportation, designing a
suitable moderator-reflector unit is one of the important
issues for achieving the “high brilliance” of the
thermal neutron cloud. In this research, the optimization of
the thermal moderator-reflector of the 24Hz target station
will be conducted to optimize pulse shape and intensity. The
Monte Carlo simulation is applied to the design. PHITS and
Diffmod are used. In this presentation, at first, the
proof-of-principle simulation to reduce the absorption of
hydrogenous moderator material is introduced. The time and
energy characteristic of candidate material and structure
are simulated and analyzed. Then, according to the neutron
transportation simulation of different moderator-reflector
unit, the specific design is presented. And we will show the
result of thermal behavior and neutronic characteristics of
this moderator-reflector unit.This work is part of the
collaboration within ELENA and LENS on the development of
HiCANS.},
