Beamline Description

Insertion device

The radiation source of the BaDElPh beamline is the same Figure-8 undulator of the IUVS beamline. This undulator has two sections for a total of 32 periods of NdFeB magnets with a 140 mm period lenght and it provides a maximum photon flux of about 1015 photons/s/0.1%BW in the range 5-10 eV. The radiation spectrum (see for example the figure on the right) is composed of two sets of harmonics, conventionally defined by integer (i=1,2,3,...) and half-integer (i=1/2, 3/2,5/2,...) indices having alternatively horizontal (i=1,2,3,...) and vertical (i=1/2,3/2,5/2,...) polarization direction.   More details can be found here.
