AB  - Neutrons at a Compact accelerator-driven Neutron Source (CANS) are produced bynuclear reactions of light ions in the low MeV range impinging on a suitable targetmaterial. Within the HBS-project, we are developing a tantalum target whichmaximises the neutron yield for a 70 MeV proton beam able to withstand a heatdeposition of 100 kW. The produced neutrons with an average energy of around 1MeV need to be slowed down to thermal or cold energies depending on theinstrument requirements. The performance of this moderation process depends onthe materials and the geometry involved which requires the optimisation with MCNPand an experimental validation.For this we are planning to build a TMR prototype at the Big Karl experimental areaat the COSY facility which can be used to validate the MCNP simulations.Furthermore, it wil be used to deliver neutrons to basic neutron scatteringinstruments like e.g. a reflectometer.At the UNKEL workshop, I will present the current design of the target / moderator/ reflector assembly and the plans for the Big Karl experimental area where it will bebuild.
