Figure 1
Response curves of virtual detectors with intrinsic dead times of (a) 120 ns, (b) 0.5 µs and (c) 3 µs to the incident X-ray intensity up to 5, 2 and 1 Mcps pixel−1 for SPring-8 bunch-modes A to H. The responses were calculated using Monte Carlo simulation based on the paralyzable model. The horizontal axis ICR represents the X-ray intensity per pixel incident on the detector, and the vertical axis OCR represents the count rate measured by the detector. Note that the EMCR, as defined in this study, are the values presented in Table 1. |
