“…Additionally, recent developments in X-ray optics have demonstrated efficient focusing with large depth of focus to spot sizes of a few nanometers, using multilayer coated Kirkpatrick-Baez mirrors [13] and multilayer Laue lenses [14]. These, and new storage-ring designs that increase the brightness of synchrotron radiation by several orders of magnitude [15,16], open up new imaging modalities and opportunities for hard X-ray cellular microscopy that we explore here.…”

X-ray imaging techniques have proven invaluable to study biological systems at high resolution due to the penetration power and short wavelength of this radiation. In practice, the resolution and sensitivity of current X-ray imaging techniques are not limited by the performance of optics or image-recovery methods but by radiation damage. We propose the use of Compton (inelastic) X-ray scattering for high-resolution cellular imaging and provide a study of a scanning microscope geometry that requires a dose to achieve a given resolution that is three orders of magnitude lower than for coherent (elastic) scattering. We find that the dose per imaging signal is minimized at a photon energy of 64 keV. This corresponds to a short enough wavelength (0.02 nm) to provide nanometer transverse resolution and micrometer depth of field for tomographic imaging of whole cells. The microscope could be implemented at future high-energy and high-brightness synchrotron-radiation facilities to provide images of unsectioned and unlabeled cells in their native conditions at enough detail to bridge the techniques of super-resolution optical microscopy and cryo-electron microscopy. © 2018 Optical Society of America under the terms of the OSA Open Access Publishing Agreement OCIS codes: (110.7440) X-ray imaging; (340.7460) X-ray microscopy; (170.3880) Medical and biological imaging.

“…Nevertheless, new opportunities as well as challenges exist, not in the least pushed forward by the availability of high brightness sources with high optical quality. New generations of XUV sources, including Diffraction-limited Storage Rings (DLSR), 164 Free Electron Lasers (FEL), 165,166 High Harmonic Generation sources, 167,168 and high power EUV lithography sources, have been or are coming on line. The new DLSR and FEL sources will provide 3-10 orders of magnitude higher brightness with much better coherence than the current generation of storage rings.…”

Extreme ultraviolet and soft X-ray (XUV) multilayer optics have experienced significant development over the past few years, particularly on controlling the spectral characteristics of light for advanced applications like EUV photolithography, space observation, and accelerator- or lab-based XUV experiments. Both planar and three dimensional multilayer structures have been developed to tailor the spectral response in a wide wavelength range. For the planar multilayer optics, different layered schemes are explored. Stacks of periodic multilayers and capping layers are demonstrated to achieve multi-channel reflection or suppression of the reflective properties. Aperiodic multilayer structures enable broadband reflection both in angles and wavelengths, with the possibility of polarization control. The broad wavelength band multilayer is also used to shape attosecond pulses for the study of ultrafast phenomena. Narrowband multilayer monochromators are delivered to bridge the resolution gap between crystals and regular multilayers. High spectral purity multilayers with innovated anti-reflection structures are shown to select spectrally clean XUV radiation from broadband X-ray sources, especially the plasma sources for EUV lithography. Significant progress is also made in the three dimensional multilayer optics, i.e., combining micro- and nanostructures with multilayers, in order to provide new freedom to tune the spectral response. Several kinds of multilayer gratings, including multilayer coated gratings, sliced multilayer gratings, and lamellar multilayer gratings are being pursued for high resolution and high efficiency XUV spectrometers/monochromators, with their advantages and disadvantages, respectively. Multilayer diffraction optics are also developed for spectral purity enhancement. New structures like gratings, zone plates, and pyramids that obtain full suppression of the unwanted radiation and high XUV reflectance are reviewed. Based on the present achievement of the spectral tailoring multilayer optics, the remaining challenges and opportunities for future researches are discussed.

“…ID radiation sources are far more intense and attractive to scientists than BM sources and so it would be advantageous to reconfigure the DBA cell to include a second ID in between the 2 dipoles. There is also a great deal of interest now in building much higher brightness Diffraction Limited Storage Rings (DLSRs) which generally employ Multi-Bend Achromats (MBA) whereby the horizontal emittance is reduced in inverse proportion to the cube of the number of bending magnets, Eriksson et al, (2014).…”

Abstract.A major project is underway at Diamond Light Source to remove one of the 24 Double Bend Achromat (DBA) Storage Ring cells and replace it with a Double Double Bend Achromat (DDBA). In this way a new Insertion Device (ID) straight can be created and so ID light can be produced and delivered to a beamline previously only capable of receiving Bending Magnet (BM) radiation. This project is in support of the micro-focus Protein Crystallography (MX) beamline VMX-m which is scheduled to take users towards the end of 2017. This paper describes the Engineering Design of the DDBA project in more detail and gives the current status of the project.
