## Summary

Diamond Light Source Limited, a central government public authority based in Didcot, United Kingdom, has awarded a contract for the supply of Primary Electron Beam Position Monitor Supports as part of its Diamond-II upgrade programme. The tender, titled "9003417 - Supply of Primary Electron Beam Position Monitor Supports," is classified under the Miscellaneous fabricated products and related items industry category. The procurement process was conducted using an open procedure and culminated with the contract being signed on 6th January 2026, and the contract will run until 8th January 2027. With a total contract value of £1,015,744.80, the procurement aims to manufacture 103 support structure assemblies critical for enhancing the Diamond-II facilities situated on the Harwell Science and Innovation Campus.

This tender presents significant opportunities for businesses specialising in the manufacturing and supply of complex structural assemblies, particularly those experienced with precise engineering fabrication involving materials like Invar and stainless steel. As this process demanded high technical quality, experience, and capacity, companies with expertise in providing high-precision fabrication solutions are well-suited to similar future contracts. Furthermore, the involvement of small and medium enterprises (SMEs) like Revol TT Consulting, which was contracted to fulfil this requirement, highlights potential openings for smaller firms to engage in high-value, technically demanding projects.
