Description

Located on the Harwell Science and Innovation Campus in Oxfordshire, Diamond Light Source (DLS) is a leading-edge facility for science, engineering and innovation. Diamond

allows researchers from academia and industry to investigate the structure and behaviour of the world around us at the atomic and molecular level.

To continue delivering the world changing science that Diamond enables, the facility is being upgraded to Diamond-II, a coordinated programme of development that combines a major

machine upgrade with new instruments and complementary improvements to optics,detectors, sample environment and delivery capabilities, and computing, as well as

integrated and correlative methods. This will be transformative in speed and spatial resolution and will offer users streamlined access to enhanced instruments for life and

physical sciences.

The scope of the contract is to design, manufacture and deliver one single and one double horizontally deflecting mirror system to the performance specification using a shared concept.

Each mirror optic will have a motorised bender, cooling system, optic diagnostic and motorised 3-point kinematic motion system. Each Mirror System will have an Ultra High Vacuum (UHV) vacuum vessel, support structure and adjustments for alignment.
