DLSITT1097 - Main Septum Magnets for Diamond-II
The contract covers the detailed design, manufacture, quality control, testing and delivery of two out-of-vacuum main DC/permanent-magnet (PM) septum magnets for Diamond Light Source’s Diamond-II facility, including integrated vacuum vessels, support stands and associated spares. The buyer, Diamond Light Source Limited, operates the UK’s national synchrotron science facility at the Harwell Science and Innovation Campus in Oxfordshire, supporting academic and industrial research in life and physical sciences. The magnets must be physically identical but configured with inverted input and output ends and inverted fields for booster extraction and storage-ring injection, with rotationally symmetric support frames and external service connections on the bending-channel side. The estimated contract value is £400,000, although no contract duration or delivery timeframe is stated. Delivery is in UKJ14, United Kingdom, with the equipment intended for installation at Diamond’s Oxfordshire facility. The critical qualification requirement is the ability to meet the technical specification for design, manufacture, quality control and testing of these specialised accelerator magnets.

From the official 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 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 ...
