摘要：

We present a here a non-parametric analysis of x-ray spectra for experiment E125 performed at GSI-FAIR in Darmstadt. This experiment measured intra-shell transitions of highly charged uranium with a twin-arm Bragg spectrometer equipped with x-rays CCDs. The method consists in slicing the CCD image and calculating the centroids of the lines, then adjusting the slice size in order to remove background. Due to the low count rate, we reveal the limitations of this method which provides an accuracy of only a few pixels, far from the sub-pixel requirement.
