(a) Calculated brilliance distribution of synchrotron radiation from the FlexPES LPU with 500 mA in the ring and 0.1% bandwidth of the monochromator. (b) Calculated undulator spectra (first harmonic) for the gap of 20 mm and the acceptance cone of 100 µrad × 100 µrad in the case of straight (red) and tapered by 1 mm (blue) magnet arrangement. (c) Same as (b) but measured experimentally with a photodiode after the exit slit. |
