## About this tender

Located on the Harwell Science and Innovation Campus in Oxfordshire, Diamond Light

Source (DLS) is a leading-edge facility for science, engineering and innovation. Diamond

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 manufacture a number of Production Secondary Photon

and Beam Port Absorber assemblies as defined in the specification, which will be required

for the assembly of the Diamond-II Storage Ring. This will require several development

activities, such as design, trials, manufacture, welding, brazing, inspection, testing and

delivery to Diamond Light Source. Installation at DLS is not included.

The total number of assemblies required are as follows: (including the First Articles):

- 6 off - LM Photon Leg Absorber Assy.
- 20 off - SM Photon Leg Absorber Assy.
- 12 off - BPA Assembly
