本文提出了一个预测CCD对软X射线谱的输出响应的理论模型。该模型模拟了最终限制CCD性能的四个基本参数：量子效率、电荷收集效率、电荷转移效率和读取噪声。各种CCD结构的模拟结果，并提出了一般的结论，实现一个实际的平衡的灵敏度，能量和空间分辨率的AXAF仪器。我们比较分析的结果，现有的国家的最先进的CCD和项目的改进，将在不久的将来。
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.
