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 coordinated 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 of materials, manufacture, assembly,
test and delivery of two White Beam Slit systems (S1 and S2) for the Diamond-II new
flagship beamline I17. The WBSs will be used for defining the size and divergence of the
beam, controlling the heat load on downstream optics, and providing diagnostic
information about the beam. Each system includes the slit blades and their actuators,
cooling system, vacuum vessel, support and manual positioning system.
The I17 beamline will be a soft x-ray beamline operating in the energy range from 250 eV
to 3.5 keV. The beamline will include a series of optical components to focus the beam at
the exit slits to which will provide a secondary source for sample illumination.
The purpose of the white beam slits is to define the size and power of the beam impinging
on mirror M1, to define the dimensions of the accepted beam after deflection from M1,
and to provide the ability to tune between flux and transverse coherence.
