Adaptation of a Kratky camera to use with a one dimensional position sensitive detector

A Kratky small-angle X-ray camera was modified so as to allow the use of a one dimensional position sensitive detector with it. The modification was designed in such a way that most of the calibrations, necessary for subsequent correction of the collected intensity data, can be performed with little alteration in the collimation geometry or the electronics settings. In particular, the calibration of the uniformity of detector efficiency can be performed by repeated vertical travel of the detector at a constant speed across a beam scattered from a sample. A much higher speed of data collection, with no increase in the background noise nor any loss in the angular resolution, has been achieved in comparison to a regular Kratky camera operating in step-scanning mode. The practical utility of combining the PSD with a Kratky camera for studies of isotropic samples has been demonstrated.
