Paper Abstract
The Italian Free Electron Laser (FEL) facility FERMI@Elettra has started to produce photon radiation at the end of
2010. The photon beam is presently delivered by the first undulator chain (FEL1) that is supposed to produce photons in
the 100-20 nm wavelength range. A second undulator chain (FEL2) will be commissioned at the end of 2011, and it will
produce radiation in the 20-4nm range.
The Photon Analysis Delivery and Reduction System (PADReS) was designed to collect the radiation coming from both
the undulator chains (FEL1 and FEL2), to characterize and control it, and to redirect it towards the following beamlines.
The first parameters that are checked are the pulse-resolved intensity and beam position. For each of these parameters
two dedicated monitors are installed along PADReS on each FEL line. In this way it possible to determine the intensity
reduction that is realized by the gas reduction system, which is capable of cutting the intensity by up to four orders of
magnitude. The energy distribution of each single pulse is characterized by an online spectrometer installed in the
experimental hall. Taking advantage of a variable line-spacing grating it can direct the almost-full beam to the
beamlines, while it uses a small fraction of the beam itself to determine the spectral distribution of each pulse delivered
by the FEL.
The first light of FERMI@Elettra, delivered to the PADReS section in late 2010, is used for the first commissioning runs
and some preliminary experiments whose results are reported and discussed in detail.
