DLSITT1097 - Main Septum Magnets for Diamond-II
Authority: DIAMOND LIGHT SOURCE LIMITED (Central government)
What is being bought
Published requirement descriptionLocated 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 this contract is to carry out the detailed design, manufacture, quality control, testing and delivery of two out-of-vacuum main DC/PM septum magnets, with integrated vacuum vessels, on support stands, as well as some spares.
The two septum magnets are physically identical but will be installed with input and output ends inverted for booster extraction bend to the left, and storage ring injection bend to the right. This means that the magnet fields are also inverted, and also that the support frame should be rotationally symmetric so that the services connections are on the outside (bending channel side of the support frame) in each case.

How DIAMOND LIGHT SOURCE LIMITED buys Magnets (CPV 3163) — and who usually turns up
DIAMOND LIGHT SOURCE LIMITED’s own published record, next to the South East England market for the same work. Frameworks and DPS are kept out: they attract a different number of bids. Whole-market view: Magnets (CPV 3163) →
How the contest usually goes
Left: this authority. Right: the market where the work is delivered. Bids and award-vs-estimate pairs are per lot, from contested contracts only — direct awards (including PA 2023 transparency notices) report one bid by definition and are left out. On Procurement Act 2023 notices the count is the tenders assessed at the final stage, not every submission received; pairs compare like with like (VAT-exclusive, or VAT-inclusive on both sides). Empty means nothing was published, not filled in from elsewhere.

Coverage and what to read with care
- Each tile explains itself. The on a figure says what it is, how it is counted and which scope this notice’s own record came from (class, division, all categories, or the authority’s 24-month row). The two columns are never blended and nothing is filled from a UK-wide figure; an empty tile means the source published nothing usable. Long form: Methodology.
- Coverage. Roughly 40 % of notices publish a bid count; about half publish an ITL1 delivery location, so the market column reads the authority’s registered region when the notice has none (labelled). About 30 % of award-vs-estimate pairs are exact matches — the buyer published the award at the estimate. n is on every figure; a thin sample is muted, never hidden.
- “Match” and “relevance” are model scores from the nightly matcher, not published facts. Find a Tender does not publish who is bidding. Never shown: contact details, payment behaviour, or a recommended price.
