Abstract :
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.
