Description

The High Brilliance neutron Source (HBS) project [1] aims for the development of compact, scalable, accelerator driven neutron sources. These are needed to facilitate the installation of a network of low to medium flux sources in Europe and close the developing supply gap for science and industry.
The NOVA ERA (Neutrons Obtained Via Accelerator for Education and Research Activities) [2] branch of the HBS project focusses on a low flux solution to be operated at universities, research institutes or industry laboratories. It uses a low power proton beam of 10 MeV to produce neutrons in a beryllium target via nuclear reactions. The neutrons are moderated in a compact system of thermal and cold moderators before they are extracted and transported to the instruments.
We will present the MCNP simulations used for the optimisation of neutron flux and brilliance in the extraction channels. In addition, we will introduce a measurement of the neutron yield produced by protons and deuterons and show a comparison with the simulated results to provide a quantitive legitimisation of the applicability of our simulations.
