“…The ring was in TOP-UP mode. The RIXS measurement chamber of the HOR-NET endstation was used, which is illuminated by an 8 segment parallel/perpendicular figure-eight undulator [92]. The beamline monochromator is an entrance-slitless variable-included-angle Monk-Gillieson mounting type with a varied-line-spacing plane grating (VLS-PGM).…”

“…The same arguments hold for a segmented crossed undulator system (Tanaka and Kitamura 2004). A segmented crossed undulator scheme with eight planar horizontal and vertical figure-8 undulators and seven phase shifters has successfully been installed at SPring-8 (Yammamoto et al 2014). Recently, the idea of a segmented crossed undulator was analyzed as an option for an X-ray SASE FEL (Geloni et al 2011).…”

Periodic magnetic structures, i.e., undulators and wigglers, have been used for nearly 40 years as sources of brilliant synchrotron radiation. Today, sophisticated undulator designs provide many degrees of freedom such as photon beam energy, variable polarization, and orbital angular momentum. Specific designs efficiently suppress higher orders or reduce the on-axis power density. All tuning parameters are required to be freely accessible by the users. Still, the majority of undulators is based on permanent magnets with a clear trend to short periods and in-vacuum and cryogenically cooled systems. Similar designs are used for storage rings and free electron lasers, though the field quality requirements are different. Today, the optimization of a specific experiment follows a global approach. This includes not only the undulator design itself but also local lattice modifications to cope with ambitious designs, elaborate tracking schemes to estimate the impact on the dynamic aperture, and last but not least radiation propagation tools which transport a realistic photon beam phase space to the sample. This chapter summarizes the theory of undulator radiation and reviews the technological realization of undulators and wigglers. Operational issues are discussed, as well.

“…[40][41][42] Therefore, multilayers are commonly used as a polarizer or phase retarder in the XUV region. [43][44][45][46][47] To extend the working bandwidth of polarizers in applications, the aperiodic multilayer system can be used as an alternative for the double-polarizer scheme 48 or the laterally graded multilayer. 49 The polarization degree or phase shift has to be taken into account in the merit function during multilayer design to achieve the broadband effect.…”

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.
