The Laue technique shortens the time required to measure integrated intensities for X‐ray structure determination. The Laue diffractometer presented here is a δ ‐circle diffractometer equipped with an ordinary low‐cost photomultiplier‐scintillation‐crystal combination. Stepper‐motor control devices and the multichannel analyzer (MCA) were originally developed for this particular purpose. These components are equipped with efficient microprocessor technology. A personal computer with graphic facilities is used for processing. Using special procedures in the analysis and the measurement of data, the disadvantages of a scintillation counter may be avoided or reduced.
