| Abstract: | A driving system for θ-angular displacement has been developed and successfully used for the model BD-1 high accuracy diffractometer. This system, which has high accuracy and stability, is controlled manually or by computer. Control sensitivity 0.29’/V, accuracy σ=±0.12. In the paper, principle and method used to fine adjust angle, line principle are discribed. |
