Fig. 5: Photon flux at beamline ID10.
From: The Extremely Brilliant Source storage ring of the European Synchrotron Radiation Facility
The curves are for flux from a single 1.6 m long, 27 mm period undulator measured with a 0.15 × 0.15 mm2 slit at 27.2 m from the source (Measurement: black line). The undulator deflection parameter was set to 1.2, corresponding to the peak brilliance. For the simulations, the rms electron beam size was kept fixed while the electron beam divergence was set to ±50% of the nominal value (red full line, red dotted (Horizontal divergence/1.5) and red dashed (Horizontal divergence × 1.5) lines).
