Simulated EDD patterns from an Fe powder sample, when different storage-ring fill patterns of the ESRF storage ring are assumed: (a) spectrum without pile-up and dead-time effects, (b) spectrum in uniform fill, and (c) spectrum in 16-bunch mode. The source is the AMPW of ID15 with the full field of 1.85 T. Symmetrical transmission geometry is used, the sample thickness is 1 mm, the scattering angle 2θ is 5°, the total count rate is 1.5 × 104 counts s−1, and the shaping time of the amplifier is 0.5 µs. The total pile-up count rate is 910 counts s−1. Background due to Compton scattering has been added. |
