The neutron optics design and performance for VULCAN ' the SNS Engineering Diffractometer ' is presented. A gradually tapered focusing neutron guide is used to deliver desired beam divergence at sample position. Selection of instrument resolution is achieved with an interchangeable guide-collimator system in the last 3-m of the neutron guide system. The effect of focusing on instrument resolution was evaluated and the strategy for detector deployment is discussed.
