| 520 | _ | _ | |a Compact accelerator-based neutron sources (CANS) are an emerging technology that enables scientists to analyze the dynamics and structure of matter. One of these projects is the High Brilliance neutron Source (HBS) project, which aims to tailor the neutron beams to meet requirements for different instruments [1]. A key component in the optimization process is the development of the target-moderator-reflector (TMR) system, where the moderator plays an important role in accumulation, moderating, and emitting neutrons towards several instruments through extraction channels. This study investigates the mutual influences of several extraction channels on the neutron flux and the beam divergence compared to a one extraction channel system.To understand the production, moderation and propagation of neutrons Monte Carlo particle-tracking codes, such as MCNP and PHITS can be used. Simulations using the PHITS program have first been performed for a single extraction channel system to observe moderator design effects on the beam divergence and the peak neutron flux emitted towards the instrument. Lastly, several arrangements of multiple extraction channels have been simulated to investigate the influence of additional extraction channels on the flux and the beam divergence.The results achieved in this study show that the influence of multiple extraction channels on the thermal neutron flux is minimal depending on the amount of moderator material that is used and on the arrangement of the channels. The insights gained from this work contribute to the continuous development of the HBS project and provide helpful information for the optimization of such a neutron source and design of neutron extraction channels in forthcoming neutron source facilities.[1] T.
