Summary of the contracting process

Diamond Light Source Limited is procuring two mirror systems for the I14 Imaging Beamline at its Diamond-II upgrade facility on the Harwell Science and Innovation Campus in Oxfordshire. The requirement covers the complete supply chain: design, manufacture, assembly, testing, delivery, installation and commissioning of the systems. These are mirrors for a long, hard X-ray beamline used for hard X-ray nanofocusing experiments, where vibration control and stability are critical. The procurement is for goods in the specialist scientific and optical equipment sector. The work will be delivered at Diamond Light Source’s facility in Oxfordshire, with the buyer based in Didcot. The equipment will support improved speed, spatial resolution and research access for academic and industrial users of the science facility.

The process has reached tender: Diamond Light Source invited offers through an open procedure. Bids were to be submitted by 12:00 on 28 August 2026, with electronic submission allowed in English; the stated arrangements also included sending a hard copy. The evaluation decision was due by 14 September 2026 at 23:59. The contract period runs from 28 September 2026 to 17 March 2028. The estimated value is £600,000 excluding VAT, or £720,000 including VAT. There is one lot, and the opportunity is identified as suitable for SMEs. Evaluation is based on price at 40%, technical quality at 25%, experience and capacity at 25%, commercial considerations at 5%, and delivery at 5%.

This opportunity suits specialist suppliers of precision X-ray, scientific or optical mirror systems able to manage a complete design-to-commissioning delivery. Bidders need to demonstrate that their designs meet demanding vibration and stability requirements for hard X-ray nanofocusing. Evidence may include finite element analysis, together with test and performance data from comparable systems previously built. Relevant capability therefore includes precision engineering and optical design, manufacture and assembly, rigorous testing, safe delivery, installation and commissioning, supported by credible experience and sufficient delivery capacity. The evaluation gives substantial weight to technical quality and to experience and capacity, so suppliers will need a technically robust solution and evidence of successfully delivering similar high-stability mirror systems. The procurement is expressly suitable for small and medium-sized enterprises.

Notice Information

Notice Title

DLSITT1104 - Supply of I14 Beamline M1 and M2 Mirror Systems for Diamond Light Source

Notice Description

Located on the Harwell Science & Innovation Campus in Oxfordshire, Diamond Light Source (DLS) is a leading-edge facility for science, engineering and innovation. DLS 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 scope of the contract is for the design, supply, manufacture, assembly, test, delivery, installation and commissioning of 2 mirror systems for the I14 Imaging Beamline. This is a long hard X-ray beamline designed for hard x-ray nano focussing experiments, so stability is of the utmost importance. DLS will require the supplier to demonstrate that their proposed designs meet the vibration and stability requirements. This can be done using finite element analysis (FEA) together with evidence of test and performance data from similar previously built systems. See specification for further details.
