Abstract

VENUS, a world‐class versatile neutron imaging instrument, is under construction and is expected to be completed and ready to start commissioning in 2023. The range of cold to epithermal neutrons at SNS will give users of VENUS access to novel imaging methods, as well as to significantly improved existing methods. Both the beam, which contains a large fraction of high-energy neutrons, and the desire for a large footprint on the detector are challenges for shielding design and budget, because the driving cost for the instrument is the front-end and instrument cave shielding. For cost reasons VENUS baseline design is optimized with respect to both the instrument cave footprint and its wall thickness, and beam line shielding is tailored along the beam. Analyses are performed with the Monte Carlo particle transport code MCNPX version 2.7.0. Numerous analyses are performed to meet space and cost constraints and to satisfy instrument requirements.
