Description

Abstract

This presentation introduces the new design features implemented in the collimator of the European Spallation Source small-angle neutron scattering instrument SKADI.

The first part focuses on the flexible beam-shaping concept achieved through a set of adjustable slits, allowing a wide range of experimental configurations. The integration of a VSANS option is also presented, extending the instrument capabilities toward very small scattering vectors.

The second part describes the practical and ergonomic features of the telescopic collimator nose. Its foldable design greatly facilitates access during maintenance operations, while its manual extension and retraction can be performed smoothly and with minimal effort, even when the collimator is under vacuum.

These developments aim to improve both instrument performance and operational usability for users and technical staff.

Key Words

Collimator, telescopic snout, slits, ergonomy, pneumatic assistance
