Abstract : An automated x-ray diffractometer has been designed and built to obtain pole figure data on polymeric samples. The pole figure goniometer is automatically driven, in a prefixed, constant increment program, by two pulse motors, allowing the operator to determine the complete distribution pattern for a given h k 1 plane automatically. The results are punched out on IBM cards; two programs have been written to process these data on the IBM 1620 computer. The first program computes the x-ray intensity at each sample orientation, corrected for absorption, polarization, background, and incoherent scattering. The second program uses these intensity data to obtain locations of constant-intensity contour lines.
