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.

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)
