DLSITT1100 - Supply of APPLE-II Undulator for Beamline K07 for Diamond Light Source

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, manufacture, test, and delivery to DLS of one complete eight axis out-of-vacuum APPLE-II undulator, subject to the performance specification, together with all the necessary drawings and documentation to ensure the

insertion devices (IDs) can be operated and maintained without Supplier support.

The APPLE-II undulator must comprise of an out-of-vacuum permanent magnetic structure with a period length of 64 mm, designed to operate over a physical gap range of 14 to 65 mm, where physical gap refers to the minimum clearance between the upper and lower magnet surfaces, taking the magnet coating thickness into account.
