## Summary

Diamond Light Source Ltd, situated on the Harwell Science and Innovation Campus in Oxfordshire, is well-known for its advanced scientific research capabilities. They have recently awarded a contract for the supply of power converters for their Diamond-II Booster BF and quadrupole magnets. The procurement, valued at £335,782.94, was conducted through an open procedure and falls under the industry category of power converters (CPV - 31121110). This project is part of the larger Diamond-II upgrade, which aims to enhance scientific instruments and computing capabilities. The awarded contract, starting from 23 August 2024 to 7 June 2027, has been secured by Energy Technology S.R.L. (OCEM), and the delivery is to the South East region of the United Kingdom.

This tender provides an exciting opportunity for businesses, particularly those specialising in power electronics and magnet control systems, to collaborate in cutting-edge scientific development. SMEs are particularly encouraged to participate, given the inclusivity criteria set forth by Diamond Light Source Ltd. The procurement seeks innovative solutions that could potentially influence future scientific breakthroughs. Suitable candidates include companies capable of producing high-fidelity power converters with the flexibility to propose alternative arrangements to enhance the stability and performance required. Engaging in such prestigious projects offers significant growth and the possibility of establishing a long-term relationship with a leading scientific research facility.

## Notice

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 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 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 subject of this call for tender are the power converters for the Booster BF and quadrupole magnets as indicated below. BF Number of Magnets: 36 Connection Arrangement: Series Number of Power Converters: 1 Quadrupole Number of Magnets: 4 per converter Connection Arrangement: Series Number of Power Converters: 5 The solution foreseen for both types of power converters is two quadrant H-Bridges fed from a DC bus/capacitor. The voltage on the capacitor is controlled by a boost regulator fed from an AC/DC SMPS, as shown in Diagrams 1 and 2. This has the advantage of presenting a fairly constant load to the ac distribution system, with energy circulating between the DC bus capacitor bank and magnets. The Booster Quadrupole power converters could have a common DC bus/capacitor and AC/DC SMPS. The contractor may propose an alternative arrangement. There will be three variants of the Booster Quadrupole power converters. They will all have the same power circuit, but two variants will have reduced current control ranges to achieve greater repeatability, resolution, and stability. This will be achieved by fitting different DCCTs and/or current sense resistors.
