Energy spectrometer on a diffractometer using a charge-coupled device X-ray detector

A charge-coupled device (CCD) X-ray detector for inelastic X-ray scattering was installed at beamline BL-4C of the Photon Factory at the High Energy Accelerator Research Organization in Japan. A wavelength-dispersive X-ray spectrometer was mounted on a six-circle diffractometer. Energy spectra were obtained by the CCD X-ray detector and a curved highly oriented pyrolytic graphite analyser. By the combination of energy spectroscopy and diffraction, simultaneous real-time data acquisition of both the momentum and the energy transfer was performed.
