Description
The beam axis of any neutron instrument is a very important property, with wide-ranging implications for beam shaping, shielding, and component interfaces. New instruments and institutes employ more complex trajectories for their neutron beams to further optimise performance and for operational reasons. While this is not inherently a problem, the precise definition and communication of the axis- and interface-specifications to suppliers is a key challenge to ensure components meet scientists’ requirements. Due to the complex dependencies between subsystems, errors or uncertainties can delay a project significantly.
In this presentation, I outline the aspects of a neutron guide system design affected by the axis layout. I demonstrate different approaches to the beam axis definition used by customers in the past, potential pitfalls, and propose initial guidelines towards best practices that accommodate the uniqueness of individual instruments while enabling clearer, more efficient communication between instrument designers and component suppliers
