摘要：We present the results of our analysis of the performance of the High Time Resolution Spectrometer (HTRS) studied with aMonte-Carlo simulation of the photon imaging and detection processes. The simulation of the photon imaging is based on a model of the X-ray optics with the particular effective area distribution of the International X-ray Observatory (IXO) Silicon Pore Optics (SPO) design. The detector was simulated with analog and with digital readout electronics. We have analysed the photon distribution on the HTRS detector at its particular out-of-focus position taking into account instrument misalignment effects within the margins imposed by the instrument requirements. We have studied different pixel geometries and analysed the bright source performance with respect to pile-up.
