Abstract: The concept for the accelerator-driven High Brilliance neutron Source (HBS) is currently being in active design phase. The overall key optimization parameters in the design of this novel neutron source are: maximum brilliance at the instruments, rather compact dimensions, flexibility and cost efficiency. In this respect thorough and detailed simulations by means of particle transport codes are of a great importance. The simulated performance parameters, like neutron yield from the target, neutron fluxes at the cold and thermal moderators, achievable brilliance at the extraction channels give a rather promising outlook for the performance of future instruments to be built at the HBS neutron source. We are going to present the latest achievements of the work of the HBS simulation group regarding optimization of the Target- Moderator-Reflector (TMR) assembly. In addition, our current work on combining the results of these simulations with the design and development of the HBS instrument suite will be discussed.
