Description


Figure 2. Improvement in spectral resolution produced by charge injection. Shown are X-ray pulseheight spectra of an 55Fe source under pre-irradiation (black), post-irradiation without charge injection (red), and post-irradiation with charge injection (green). Both the centroid and the width of the response function are degraded by the radiation, and improved by charge injection. In particular, charge injection returns the width of the spectral response function to within 10% of its pre-irradiation value.
