## Summary

Diamond Light Source Limited is buying one complete turn-key permanent magnet multipole wiggler for the K14 beamline as part of the Diamond-II upgrade. The requirement covers design, manufacture, testing and delivery of the wiggler, including a support stand and positioning system, plus a lifting frame for crane handling. The supplier must provide drawings and documentation so the insertion device can be operated and maintained without supplier support if required. The specified design has a 116 mm period length, 6.5 periods, 13 full poles and a minimum physical gap of 14 mm, optimised for a 1.3 tesla peak field. This is a specialist magnet and accelerator-component supply delivered to Diamond Light Source at the Harwell Science and Innovation Campus in Didcot, Oxfordshire.

The process reached tender: Diamond Light Source invited offers through an open procedure. Bids were due by 21 September 2026 at 12:00. Offers could be submitted electronically by email, with a hard copy also requested at Diamond Procurement, Diamond House, Harwell Science and Innovation Campus, Didcot. The award decision was due by 5 October 2026 at 23:59:59. The contract is scheduled to run from 20 October 2026 to 17 December 2027. The estimated value is £180,000 excluding VAT, or £216,000 including VAT. There is one lot and the opportunity is suitable for SMEs. Evaluation is weighted 50% price, 20% technical quality, 20% experience and capacity, 5% commercial matters and 5% delivery.

This opportunity suits specialist manufacturers and engineering businesses with demonstrable capability in permanent magnet multipole wigglers, insertion devices, accelerator magnets or closely related high-precision magnetic systems. Competitors need to design and manufacture a complete engineered assembly, test it against demanding performance requirements, and deliver associated lifting, support and positioning equipment. The requirement also favours suppliers able to produce accurate technical drawings, operating information and maintenance documentation, enabling the facility to manage the equipment without relying on the supplier. Relevant experience and capacity are directly assessed, so bidders should be able to show comparable projects, suitable production and testing resources, quality controls, and the engineering capacity to deliver a bespoke system for a major national science facility.

## Notice

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.
