Abstract :
A conic glass monocapillary was developed and used at the Biological Macromolecules Station (BMS) in Beijing Synchrotron Radiation Facility (BSRF). The structure and transmission property of this optics is reported here in details. The experiments have shown that the value of full width at the half maximum (FWHM) of the X-ray beams transmitted through this optics was nearly unchanged within a short distance. This is very convenient for further measurement of samples. The power diffraction experiments of CeO2 revealed that the Debye rings are much clearer in the case of applying this optics. The ratio of error in the diffraction peak position is reduced significantly to the value as less as 0.042%.
