摘要： An x-ray diffractometer is disclosed having a position-sensitive detector which is quasi-continuously movable in stepped fashion around a sample by a stepping motor. Output signals triggered by x-ray quanta are output from the position-sensitive detector and converted by an electronic evaluation unit into a time duration corresponding to a position of a particular x-ray quantum in the detector. The time-digital converter connected to the evaluation unit converts the time duration to a digital signal. A digital adder is provided having three inputs. The first input connects to an output of the time-digital converter, the second input connects to receive a digital value generated by a counter associated with the stepping motor, and a third input connects with a digital region selector. An output of the adder connects to a multi-channel analyzer having a plurality of regions therein for analyzing various desired measurement applications. The digital region selector addresses the appropriate region in the analyzer for a desired measurement application.

摘要： An X-ray powder diffractometer functioning as a goniometer is disclosed wherein a monochromatic X-ray source is provided together with a sample to be analyzed and a detector means with position sensitive behavior. A transport system for digitally controllable advance drive is provided so as to advance the detector along an arc suited for a Guinier method for transmission and/or back reflection beam direction. An electronic analysis system is provided for preparing an intensity diagram of a local distribution of diffracted radiation for a given position location 2.theta. of the detector. The analysis system includes an amplifier/discriminator for delivering a time signal corresponding to the position/location of a respective single photon event received from the detector. A time-digital converter connected to the amplifier/discriminator is also provided together with a multichannel analyzer connected to the time-to-digital converter by a digital adder. The position-sensitive detector is located diametrically opposite the sample on the Guinier circle so as to form an assembly. This assembly is rotated in the primary beam such that the primary beam always impinges on the sample, and the detector is always in a focus of the diffracted radiation.
