UK Public Sector Contracts & Tenders

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 to design, manufacture, supply, test and deliver one Front end for the K14 beamline in Diamond-II. The Front End will be located in a restricted area so it must be capable of continuous operation over long periods without maintenance. The support frames must be rigid construction and constructed so that they minimise the effects of ground vibrations. The support frames must be supported from the floor with three manually adjustable feet to allow them to be accurately surveyed into position.

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 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 this contract is to carry out the detailed design, manufacture, quality control, testing and delivery of 4 in-vacuum kicker magnets and power supplies. The main parts of all four magnets will be identical with individual matching pieces for each magnet. One magnet is used for injection and requires a rapid return to zero field, the other three are used for extraction and require a rapid rise to nominal field which is also stronger than in the injection magnet. It is envisaged that these differences should be achieved in the power supplies i.e. there will be two different power supply types, which should use as many common components as possible. The DLS design envisages a common magnet structure and main vessel for all 4 kickers with bespoke taper/matching pieces for each location. Use of a common power supply design tuned for the two different requirements is desired but different designs would be considered with appropriate justification.

This will be transformative in speed and spatial resolution and will offer users streamlined access to enhanced instruments for life and physical sciences. The logistics model devised that underpins this programme mandates a suitable offsite storage facility to be secured for a period of three years starting sometime during 2025. This will serve as a cross-dock style operation with inbound material being checked, identified and prepared for despatch to the point of installation in the synchrotron and surrounding buildings in a timely fashion. The material consists of technical equipment delivered from around the world normally in wooden crates or pallets. The requirement is for Warehouse space up to 3750 sq. metres, no less than 1350 sq.metres. This pace need not be contiguous and can be spread across up to five different sites. There may also be a kitting process established. An estimated 20% of the footprint will be racking and shelving. The remaining open floor area will be used for marshalling the inbound inventory and setting out for inspection and despatch.

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 for the Design, supply of materials, manufacture, test, and delivery of two sets of three mirror optics for the I17-CSXID (Coherent Scattering and X-ray Imaging Diffraction) beamline. a) Three polished mirror optics (M1a, M3a, M5a) with Ni coatings. b) Three polished mirror optics (M1b, M3b, M5b) with Pt coatings. The optics should be clean and ready for immediate installation and use in ultra-high vacuum (UHV) conditions on the beamline. The tender specification is for the three mirrors M1, M3 and M5 as listed below. Two sets of these mirrors will be required with different coatings: • The M1 optic is a vertically-collimating optic with a sagittal cylindrical shape that deflects the beam outboard • The M3 optic is a vertically-focussing optic with a sagittal cylindrical shape that deflects the beam outboard • The M5 optic is a vertically-focussing optic with a sagittal cylindrical shape that deflects the beam inboard. To achieve the required flux at the sample position, the I17 Mirror Systems will require the ability to switch between optics with either a Ni or Pt coating. The sagittal cylindrical shape means that two set of optics will be required, with one coating on each optic.

This will be transformative in speed and spatial resolution and will offer users streamlined access to enhanced instruments for life and physical sciences. The Optics and Metrology Group at Diamond Light Source wish to procure and develop a computer-controlled optical surfacing (CCOS) machine. The CCOS machine will be used to complement the ion beam figuring (IBF) project at Diamond. It will be used to polish a variety of materials, including single crystal silicon (Si), used for X-ray mirrors, grating substrates, and multilayer mirrors substrates. It should be compatible with a range of sample sizes, up to 1000 mm (length) x 100 mm (width) x 100 mm (height). The machine should allow for polishing of various surface geometries. Using appropriate slurries and polishing heads, the machine should be capable of "super-polishing" silicon to obtain micro-roughness Sq below 0.5 nm rms, and ideally below 0.3 nm rms (as measured over a field of view of < 1mm). The machine should also be capable of deterministically polishing and correcting optical surface errors with a spatial period from 5 mm to the full length of the mirror. It should be capable of polishing strongly-curved, concave surface geometries. It is expected that the CCOS machine will be based on: a motorised stage for the workpiece (which may have one or more axes of motion, such as rotation); a motorized tool holder with at least five axes of motion (X, Y, Z, and two pivot axes A and B); a rotating polishing tool head; and a slurry feed to controllably provide polishing slurry to the tool head when it is in motion against the workpiece. An interchangeable polishing tool head that can be quickly and easily replaced, to provide suitable polishing for different sizes, shapes or materials of various optical surfaces. A simple method is also required to change the type of polishing slurry. The scope of this contract is to supply, deliver, install and commission a computer-controlled optical surfacing machine based on an interchangeable rotating tool head, motorized tool holder, mounting stage for the workpiece, and polishing slurry feed. The supplier is encouraged to comment on any aspect of the specifications and to identify possible modifications that could lead to either improved performance or reduced cost (without compromising the performance specification)
