Abstract: In any experimental discipline, raw data represents the source from which all discoveries are derived. A more strict interpretation in X-ray diffraction experiments may refer to this as primary data since any pixel counts will have been manipulated (e.g. analogue to digital conversion, dark current correction, interpolation of pixels etc.); however the fundamental idea remains: this is the closest it is possible to get to the original experimental measurements. At Diamond Light Source, the principle of secure recording and storage of the primary data was embedded in the data acquisition system from the outset. The general user does not have permission to alter or delete the raw experimental data, and the acquisition system GDA is designed to prevent over-writing of the images.
