Figure 1
Layout of the FERMI-FEL and IR laser beamlines delivering FEL and IR light to the DiProI end-station. The FEL pulses, generated by two distinct FEL amplifiers (FEL-1 and FEL-2), are delivered to the DiProI end-station by the FERMI photon transport system. The FEL pulses can be tailored by the beam defining aperture (BDA) for removing the undulator off-axis emission. The FEL beam intensity can be monitored using two different ionization chambers (I0 monitors). A gas cell, placed between the two I0 monitors, can be used to reduce the intensity of the beam according to the experimental needs. The spectral content of the photons delivered to the end-station is monitored by a single-shot spectrometer along the photon transport systems. A split–delay line unit and an active Kirkpatrick–Baez (KB) system are additional optical elements for generating two FEL pulses with controllable delay for single color time-resolved experiments and to focus the beam onto the sample, respectively. Parallel to the EUV/soft X-ray beamline, there is an IR laser beamline that provides optical laser pulses for two-color experiments (IR pump–FEL probe or FEL pump–IR probe). |
