## Summary

Diamond Light Source Ltd has completed its procurement process for the manufacturing, testing, and delivery of HOM-damped RF Cavities to upgrade its 3.5 GeV beam storage ring. The procurement was conducted under an open procedure, focusing on the industry category of "Miscellaneous general and special-purpose machinery" (CPV code 42900000). This contract awards the supply of four or five additional RF cavities similar to those installed at ALBA and BESSY light sources, contributing to the research facility's upgrade. The procurement process reached its award stage on 30th October 2024, with the contract signed off, ensuring a well-executed upgrade for continued world-changing science. The procurement is associated with the region UKJ14, reflecting where the delivery will occur.

This tender presents significant business growth opportunities, particularly for companies specialising in advanced machinery and scientific instruments manufacturing. Companies with expertise in high-precision engineering, RF technology, and experience in similar large-scale scientific projects are well-suited to compete. The tender's focus on technical quality, experience, and delivery supports opportunities for businesses to showcase innovation and competence while contributing to cutting-edge scientific advancements at Diamond Light Source Ltd. Given the high standards required and the procurement's strategic importance, it enables participating companies to strengthen their portfolio and credibility in the global scientific community.

## Notice

To continue delivering the world-changing science that Diamond enables, the facility is being upgraded. The 3.5 GeV beam in the Diamond-II storage ring will be maintained by seven (or eight) RF cavities of a normal-conducting design with damped Higher Order Modes (HOMs) similar to those installed at the ALBA light source in Barcelona and the BESSY and MLS storage rings in Berlin. Three HOM-damped normal-conducting cavities are already installed in the storage ring and so four or (five) additional cavities are required. The scope of the contract is the manufacture, test, and delivery to DLS of four (or five) HOM-damped cavities resonant at 499.511 MHz, including cavity support frames to hold the cavities in the required orientation, and base frames which support two cavities and their respective support frames.
