SAXS/WAXS-detector calibration


This Javascript does the-q-scale calibration of a 1D-SAXS or WAXS-curve in transmission mode with a Calibration sample. Enter the number of the detectable peaks, their d-values and the respective pixel values on the detector. If the origin (q=0) can be measured, it can be entered as the first peak value with d=0. The resulting equation for the q-scale is then: q = intercept + slope*pixel. Note: the linear relationship between q and pixel position is only valid over a small angular range by using a plane position sensitive 1D detector. Unit of q is 1/A if the values of the peak positions or spacing is also in A. The values of the slope and of the intercept will be displayed and the fit will be plotted.
