Abstract：
Technical specifications of Beam-line 4W1C and X-ray diffuse scattering station at Beijing Synchrotron Radiation Facility(BSRF)were discussed. Double focussed monochromatic X-ray beam,with energy resolution of 4.4×10^－4 and beam spot of 0.5mm(H)×0.3mm(V),was obtained with a bent crystal mdnochromator shaped in triangular and a cylindric mirror.Nonspecular X-ray scattering from quasiperiodic amorphous multilayer was studied.The scattering maximums formed intensity streaks in the reciprocal space having the quasiperiodic character.Intensity modulations were observed and simulations based on atomic scattering gave satisfactory results.
