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).

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.

In operation since 2007, it utilises a superconducting multipole wiggler X-ray source to deliver X-rays across a broad energy range from 20 to 80 keV to its end stations. It supports both powder and single-crystal diffraction experiments under high-pressure and variable temperature conditions. While primarily dedicated to extreme conditions research, the beamline also facilitates a broad spectrum of studies requiring high-energy X-ray scattering techniques. The D-II upgrade will increase the machine energy from 3 GeV to 3.5 GeV. The I15 Double Crystal Monochromator (DCM), as the beamline's first optical element, will consequently experience a substantial increase in power load due to this upgrade. Therefore, it is crucial to upgrade the DCM to ensure continued efficient and effective beamline operation without significant flux loss under the higher power load conditions on D-II. This contract covers the design, manufacture, testing, delivery, and installation of a Double Crystal Monochromator (DCM) system, guided by the properties of the X-ray source and the performance requirements set out in the specification. The Supplier is responsible for delivering a complete and functional system, including all necessary mechanical, electrical, and cooling components, suitable for integration into the available DLS infrastructure.

The scope of this contract is to Supply, deliver, install and commission a Fizeau laser interferometer, subject to the performance specification. The specification details the requirements for a Fizeau interferometer to accurately measure the surface quality of X-ray optics for Diamond's beamlines in the Optics Metrology Lab (OML). The Optics & Metrology group at Diamond requires a Fizeau interferometer with a ~ 150 mm diameter exit laser beam to measure the slope and figure error of synchrotron X-ray mirrors and crystals. Such optics are manufactured from single-crystal silicon, often with a metallic coating to enhance X-ray reflectivity. Advances in optical production technology, including ion beam figuring and elastic emission machining, mean that it is now possible to produce X-ray optics with figure errors less than 1 nm rms. To accurately characterise such optics, a measurement tool is required with an accuracy and repeatability
