N2 - Simulations of target-moderator-reflector system at spallation sources are conventionally <br/>carried out using MCNP/X whereas simulations of neutron transport and instrument <br/>performance are carried out by neutron ray tracing codes such as McStas. The coupling <br/>between the two simulations suites typically consists of providing analytical fits from <br/>MCNP/X neutron spectra to McStas. This method is generally successful, but as <br/>will be discussed in the this paper, there are limitations and a more direct coupling <br/>between MCNP/X andMcStas could allow for more accurate simulations of e.g. complex <br/>moderator geometries, interference between beamlines as well as shielding requirements <br/>along the neutron guides. In this paper different possible interfaces between McStas <br/>and MCNP/X are discussed and first preliminary performance results are shown.
