Abstract The Budapest Neutron Center underwent its last significant up-grade approximately 25 years ago with the installation of a cold neutron source. However, advances in instrumentation and newly emerging opportunities prompted us to plan a comprehensive modernization effort. The currently used liquid hydrogen cold source will be replaced by a new para-hydrogen one, using an advantageous low-dimensional configuration. We will discuss the cold source optimization procedure and how the requirements of various instruments influence the design. The expected performance improvements will be highlighted as a result of advanced Monte Carlo simulations.
