DLSITT1104 - Supply of I14 Beamline M1 and M2 Mirror Systems for Diamond Light Source
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 the contract is for the design, supply, manufacture, assembly, test, delivery, installation and commissioning of 2 mirror systems for the 114 Imaging Beamline.
This is a long hard X-ray beamline designed for hard x-ray nano focussing experiments, so stability is of the utmost importance. DLS will require the supplier to demonstrate that their proposed designs meet the vibration and stability requirements. This
can be done using finite element analysis (FEA) together with evidence of test and performance data from similar previously built systems.
