| Abstract: | An X-ray directional device, usually measuring the geometry relations of different positions with the crystal to be measured, has been used to measure the direction of crystal. the directional device is composed of a high voltage set for the X-ray tube, counter tube, angle scale set and signal amplifier. It employs the diffrection characteristics of X-ray tube to measure crystal. X-ray tube is an important part that greatly determines the device precision. This article discusses the influence of X-ray tube characteristics on the device precision. |
