TLDR
Developments of optics for coherent X-ray applications and their role in diffraction-limited storage rings are described.Abstract:
Developments of X-ray optics for full utilization of diffraction-limited storage rings (DLSRs) are presented. The expected performance of DLSRs is introduced using the design parameters of SPring-8 II. To develop optical elements applicable to manipulation of coherent X-rays, advanced technologies on precise processing and metrology were invented. With propagation-based coherent X-rays at the 1 km beamline of SPring-8, a beryllium window fabricated with the physical-vapour-deposition method was found to have ideal speckle-free properties. The elastic emission machining method was utilized for developing reflective mirrors without distortion of the wavefronts. The method was further applied to production of diffraction-limited focusing mirrors generating the smallest spot size in the sub-10 nm regime. To enable production of ultra-intense nanobeams at DLSRs, a low-vibration cooling system for a high-heat-load monochromator and advanced diagnostic systems to characterize X-ray beam properties precisely were developed. Finally, new experimental schemes for combinative nano-analysis and spectroscopy realised with novel X-ray optics are discussed.read more

Correlation between Photons in two Coherent Beams of Light
R. Hanbury Brown,R. Q. Twiss +1 more
TL;DR: Hanbury-Brown and Twiss as mentioned in this paper showed that photon detections in the two daughter beams were correlated: the photons were bunching together, which corresponded to a correlation in the intensity of light in two beams, which could be used to infer the angular size of distant stars.
