TLDR
In this article, a theoretical model is presented which predicts the output response of a CCD to soft X-ray spectra, and compared the results of the analysis to an existing state-of-the-art CCD and project improvements which will be made in the near future.Abstract:
A theoretical model is presented which predicts the output response of a CCD to soft X-ray spectra. The model simulates the four fundamental parameters that ultimately limit CCD performance: Quantum efficiency, charge collection efficiency, charge transfer efficiency, and read noise. Simulated results are presented for a wide variety of CCD structures, and general conclusions are presented about achieving a practical balance of sensitivity, energy, and spatial resolution for an AXAF instrument. We compare the results of the analysis to an existing state-of-the-art CCD and project improvements which will be made in the near future.read more

TL;DR: In this paper, a detailed description of the CCD response model used to compute the XRT RMFs (redistribution matrix files), the changes implemented to it based on measurements of celestial and on-board calibration sources, and current caveats in the RMFs for the spectral analysis of XRT data.

Analytic Modeling Of Charge Diffusion In Charge-Coupled-Device Imagers
TL;DR: In this paper, it is shown that the charge cloud profiles resulting from field free diffusion have broad wings that can lead to significant charge splitting between adjacent pixels, even for field-free region thicknesses ≥ 1 um.
