The 10 GeV CHEER electron storage ring will produce more than 1 MW of synchrotron radiation per turn with photon energies extending from the far infrared to the hard X-ray region. The critical energy of the synchrotron radiation spectrum will be 22 keV.Applications of hard X-rays to materials analysis are described and a discussion of some of the problems which will be encountered in implementing a synchrotron radiation facility at CHEER is presented.

We have performed the two-photon correlation measurement of synchrotron radiation in the VUV region to characterize the photon statistics of the light. The explicit bunching effect of the second-order coherence is observed, which implies that synchrotron radiation has a chaotic nature. We also estimate the electron beam emittance of a stored beam. The two-photon correlation measurement will be utilized to diagnose the storage ring and to characterize the coherence properties of X-ray free electron laser in the future.

The evolution of synchrotron radiation (SR) sources and related sciences is discussed to explain the ‘generation’ of the SR sources. Most of the contemporary SR sources belong to the third generation, where the storage rings are optimized for the use of undulator radiation. The undulator development allowed to reduction of the electron energy of the storage ring necessary for delivering 10 keV X-rays from the initial 6–8 GeV to the current 3 Gev. Now is the transitional period from the double-bend-achromat lattice-based storage ring to the multi-bend-achromat lattice to achieve much smaller electron beam emittance. Free electron lasers are the other important accelerator-based light sources which recently reached hard X-ray regime by using self-amplified spontaneous emission scheme. Future accelerator-based X-ray sources should be continuous wave X-ray free electron lasers and pulsed X-ray free electron lasers. Some pathways to reach the future case are discussed. This article is part of the theme issue ‘Fifty years of synchrotron science: achievements and opportunities’.
