Beamline Flux 

The experimental flux curves for the 2 storage ring operation energies at Elettra (i.e. 2.0 and 2.4 GeV) normalized to the beam current (300 and 160 mA respectively, typical top-up conditions) are shown below. The output flux was characterized immediately downstream of the refocusing mirror, at 14.3 m from the source, by using 2 ionization chambers behind a 0.3mm thick Beryllium window. The output curves are following closely the expected spectral dependence.
