Description
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 this contract is to design and manufacture two types of Collimator assemblies which form part of the Diamond-II Storage Ring, this will require several development activities, such as design, trials, manufacture, welding, inspection, testing and delivery to Diamond Light Sources. Installation at DLS is not included.
There will be six (6) Collimator assemblies required for Diamond-II, three Vertical and three Horizontal. These are used to collect particles lost from the electron beam and to provide machine protection for sensitive components within the Diamond-II Storage Ring, they will be fitted at specific positions around the storage ring mounted on MS Girders.
