Abstract
A horizontal two-axis diffractometer for glasses and liquids, installed at SPring-8 bending magnet beamline BL04B2, operated at 8 GeV electron energy, is described. Photon energies of 37.8 and 61.7 keV were obtained using a b ent Si (1 1 1) crystal and a bent Si (2 2 0) crystal, respectively. The ins trument has been successfully applied to measure diffraction spectra of vit reous SiO2 in transmission geometry up to scattering vector Q = 36 Angstrom (-1), and measured total structure factor S(Q) was well reproduced by reve rse Monte Carlo modelling.
