## Summary

Diamond Light Source Ltd, located at the Harwell Science and Innovation Campus in Oxfordshire, has successfully completed the procurement process for the supply of Booster & Quadrupole Power Converters as part of the Diamond-II upgrade. The procurement falls under the industry category of power converters (CPV code 31121110) and is designated for scientific research. The contract, signed on 23rd August 2024, was awarded to Energy Technology S.R.L. (OCEM) with an award value of EUR 398,740. This procurement follows an open procedure, with the tender stage having started in early 2024 and completed on 5th March 2024.

This tender presents substantial opportunities for businesses involved in the design and supply of power converters, particularly those with experience in providing technical solutions that require custom modifications to standard products. Suppliers capable of delivering innovative, high-quality solutions while meeting stringent delivery schedules will find this tender particularly attractive. SMEs specialising in advanced power solutions and possessing strong technical expertise in the field of AC/DC SMPS systems and DC bus/capacitor configurations are particularly well-suited to compete for such opportunities, fostering growth through collaboration with leading scientific research facilities like Diamond Light Source.

## 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 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.
