Summary of the contracting process

Diamond Light Source Limited sought one complete permanent-magnet multipole wiggler for its K14 beamline at the Harwell Science and Innovation Campus in Oxfordshire. The equipment is for the Diamond-II facility upgrade, supporting research in life and physical sciences. The requirement covers design, manufacture, testing and delivery of the wiggler, together with its support stand and positioning system, a crane lifting frame, and drawings and documentation sufficient for operation and maintenance without supplier support. The wiggler specification calls for a 116 mm period length with 6.5 periods (13 full poles), a minimum physical gap of 14 mm and a gap optimised for a 1.3 T peak field. This is a specialist magnet and insertion-device supply.

Diamond Light Source invited offers through an open procedure. The process reached the tender stage, but the procurement was subsequently cancelled; no reason for cancellation is stated. The single-lot requirement had an estimated value of £180,000 excluding VAT (£216,000 including VAT). The submission deadline set was 21 September 2026 at 12:00 BST, and the stated award decision date was 5 October 2026. The contract period was scheduled to run from 20 October 2026 to 17 December 2027. Evaluation allocated 50% to price and 50% to quality: technical quality 20%, experience and capacity 20%, commercial matters 5% and delivery 5%. The lot was identified as suitable for small and medium-sized businesses.

This opportunity suited suppliers able to deliver a specialist permanent-magnet multipole wiggler as a complete, integrated system, rather than provide a magnet alone. The work required capability across design, manufacture, testing and delivery, including the support stand, positioning system and crane lifting frame. Suppliers needed to demonstrate that their technical design met the specified period length, pole count, minimum gap and peak-field optimisation requirements. Experience and capacity were a substantial part of the quality assessment, alongside technical quality; delivery and commercial considerations also contributed. The documentation requirement favoured suppliers able to provide drawings and operating and maintenance information that would allow Diamond Light Source to run the insertion device without relying on supplier support. The opportunity was explicitly considered suitable for SMEs, although it called for relevant specialist engineering capability.

Notice Information

Notice Title

DLSITT1098 - Diamond-II Multipole Wiggler for K14

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 to design, manufacture, test and deliver to DLS one complete turn-key permanent magnet multipole wiggler (MPW) including support stand and positioning system and one lifting frame to allow the wiggler to be lifted by crane, subject to the specification, together with all necessary drawings and documentation to ensure the insertion device (ID) can be operated and maintained without supplier support if necessary. The MPW should have a period length of 116 mm with 6.5 periods (13 full poles). These parameters have been chosen to reduce the interference effects in the flux-energy spectrum. A 14 mm minimum physical gap is allowed, but the gap should be optimised for a 1.3 T peak field. See specification for further details.
