Power density distribution of the undulator radiation emitted in the energy range (4.4 < E < 5.4 keV) (left) and of the whole spectrum (1.0 < E < 161.0 keV) (right) through the front-end mask calculated using SRW (top), the algorithm with constant energy (CE) steps (middle) and with constant power (CP) steps (bottom). In the latter two methods, the sampling steps are 1000 and 16000 for the energies around the first harmonic and the whole spectrum cases, respectively. |
