Abstract：
Compared with the method of one dimensional small angle X-ray scattering, two dimensional small angle X-ray scattering has the advantage of being able to study non-global symmetric system, thus to obtain the information about size and shape of particles (or holes) in oriented system. In this paper we report the establishment of a two dimensional synchrotron radiation small angle X-ray scattering device in Beijing Synchrotron Radiation Facility and the data analysis method developed. The results of an experiment on pitch-based carbon fiber with this device show the voids in pitch-based carbon fiber become larger as NH 3 content in the activator decreases in the activating process.
