A white‐X‐ray four‐circle diffractometer

A white‐X‐ray ( Bremsstrahlung ) four‐circle diffractometer with a solid‐state detector [Si(Li)] has been constructed. The system is operated by a small computer with magnetic disk memories, and enables energy‐dispersive intensity measurements to be carried out with the X‐rays selected from white X‐rays. The present paper describes (1) how the present system can be used for energy‐dispersive diffractometry even with the white radiation from a standard X‐ray tube, and (2) how this system allows the measurement of the integrated intensities with almost the same accuracy as in angle‐dispersive diffractometry with characteristic X‐rays.
