## Summary

The Diamond Light Source Ltd, located in Didcot, Oxfordshire, has completed the procurement process for the project titled "Supply of 1st Collimating Mirror for Beamline K18." This project, set on the Harwell Science and Innovation Campus, falls under the industry category of mirrors (CPV 38622000). Initially published on 11th December 2024, the tender underwent an open procedure, reaching the award stage. Key dates include the tender period closing on 22nd January 2025, with the contract commencing on 10th March 2025 and ending on 23rd June 2026. The entire project aims to support Diamond-II's development programme by designing, manufacturing, and installing a sophisticated collimating mirror system to improve the facility's capabilities in producing high-resolution X-ray beams.

This contract presents substantial opportunities for businesses involved in mirror manufacturing and high-precision engineering, particularly those capable of innovation in optical technologies. Small and medium enterprises (SMEs) such as XDS Oxford Limited, which has been awarded this contract, would find this tender particularly beneficial due to its focus on high-specification custom components including motorised mechanical systems and vacuum technology. Engaging in such projects allows businesses to demonstrate expertise in cutting-edge scientific equipment, fostering growth through enhanced reputation and potential future collaborations within the scientific research sector.

## Notice

Located on the Harwell Science and Innovation Campus in Oxfordshire, Diamond is a leading-edge facility for science, engineering, and innovation. It is the largest science facility to be built in the UK for 40 years and produces ultra-violet, infra-red and X-ray beams of exceptional brightness. 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 co-ordinated 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 correlative methods. This will be transformative in speed and spatial resolution and will offer users streamlined access to enhanced instruments for life and physical science. The scope of the contract is for the design, supply of material, manufacture, assembly, test, delivery, installation and commissioning of a collimating mirror system (M1) for the K18 beamline. The minimum scope of the contract is the design, manufacture, test, and delivery of: * M1 upward reflecting, vertical collimating, white beam X-ray mirror & mechanics. * Motorized mechanical bender to adjust the curvature of M1's reflecting surface. * Motorized gravitational sag compensator. * Cooling arrangements as described in the specification. * Vacuum vessel and associated controls. * Support frame. * Interface to beamline services.
