Quantitative Determination of Pole Figures with a Texture Goniometer by the Reflection Method

Abstract

For different slit systems of a modern texture goniometer (type Siemens) the X-ray intensity reflected from textureless plane samples has been measured as function of the tilt angle {phi} and Bragg angle {theta}. The intensity curves obtained generally enable quantitative and almost complete pole figure determinations to be made with only one reflection recording, even for materials with high line density. Investigations on rolled uranium sheet with CuK{sub {alpha}} radiation showed that for reliable chart records up to {phi} {approx} 70 deg on reflections with an angular separation of only {delta}(2{theta}) = 0.7 deg, the vertical receiving slit must be limited to at least 1 mm when using a horizontal main slit of 0.5 mm, Though in this case the intensity drop off resulting from defocusing from the flat sample surface is considerable even at small tilt angles, a correction of intensity is possible also at large angles within an accuracy of {+-} 5 %. Moreover, different pole figures for one material can be compared quantitatively, without constant slit settings and recording conditions being necessary, if the intensity values of the contour lines are always referred to the background radiation.
