FERMI is the first seeded EUV-SXR free electron laser (FEL) user facility, and it is operated at Elettra Sincrotrone Trieste. Two of the four already operating beamlines, namely LDM (Low Density Matter) and DiProI (Diffraction and Projection Imaging), use a Kirkpatrick-Baez (K-B) active X-ray optics system for focusing the FEL pulses onto the target under investigation. A wafefront sensor is used as diagnostic for the characterization of the focused spot and for the optimization of the parameters of these active optical systems as well. The aim of this work is, first, to describe in detail the optimization procedure using the wavefront sensor through the minimization of the Zernike coefficients, and second, report on the final results obtained on the K-B optical system at the DiProI endstation. The wavefront sensor, mounted out of focus behind the DiProI chamber, allows to compute the intensity distribution of the FEL beam, typically a mix between several modes resulting in a ”noisy hyper-Gaussian” intensity profile, and the wavefront residual from ideal propagation shape and after tilt correction. Combining these two measures we can obtain the electric field of the wave out of focus. Propagating back the electric field we reconstruct the focal spot in far field approximation. In this way the sensor works as a diagnostic reconstructing the focal spot. On the other hand, after modelling the electric field with a Zernike polynomial it is easy and fast to optimize the mirror bending and the optical system angles by minimizing the aberrations, quantified in terms of Zernike coefficients. Since each coefficient corresponds to a single parameter, they can be minimized one at the time. Online wavefront measurements have made possible the optimization of the bending acting on the mirror curvature, and of the (pitch and roll) angle positions of the K-B system. From the wavefront measurements we have inferred a focal spot for DiProI of 5.5 μm x 6.2 μm at 32 nm wavelength, confirmed by the PMMA ablation imprints. The experimental results were compared with the predictions from simulations obtained using the WISE code, starting from the characterization of the actual mirror surface metrology. The results from simulations were found to be in agreement with the experimental measurements.

FERMI is the first seeded EUV-SXR free electron laser (FEL) user facility operated at Elettra Sincrotrone Trieste. Two of the three already operating beamlines, namely LDM (Low DensityMatter) and DiProI (Diffraction and Projection Imaging), use a Kirkpatrick-Baez (K-B) active X-ray optics system for focusing the FEL pulses onto the target under investigation. The present work reports on the final results obtained from the optimization of the K-B optical system at the DiProI endstation. The aim of the optimization is to improve the system performances in terms of quality and size of the focal spot onto the sample, controlling the fluence as well. To characterize the performances and develop reliable and reproducible focusing procedures we performed a campaign of measurements with several diagnostic systems, including a wavefront sensor mounted after the DiProI chamber. Online wavefront measurements have made possible the optimization of the bending acting on the mirror curvature and of the (pitch and roll) angle positions of the K-B system. From the wavefront measurements we have inferred a focal spot of 8 μm x 9.5 μm, confirmed by the PMMA ablation imprints. The experimental results are compared with the predictions from simulations obtained using the WISE code, starting from the characterization of the actual mirror surface metrology. The results from simulations are in agreement with the experimental measurements. Filtering the Fourier transform of the mirror surface profiles, using the WISE code we have analyzed the impact of different spatial wavelengths on the focal spot degradation. For different energies of the incident beam we established the threshold where the focal spot degradation is no longer affected by the spatial wavelengths of the K-B mirror surfaces. In the very last period we were starting to observe a degradation of the focal spot. After a metrology analysis we concluded that the problem was due to a failure of the substrate material. We temporally solved the problem checking the mounting, but we have planned an improvement of the material for the future.

Soft x-ray emission spectroscopy is a well established technique, which has seen increased interest in recent years due to the development of high brilliance synchrotron radiation facilities. Emission spectra are obtained when a hole is created by impinging photons, and an electron from the valence band decays into the core hole emitting its excess energy radiatively. The fluorescence yield is intrinsically low in the range of soft x-rays, usually less than about 0.5%, since the most probable decay channels are radiationless channels like Coster Kronig and Auger processes. Emission is over all space, but only a restricted solid angle can be collected and this further reduces the efficiency of the instrumentation. Moreover, the emitted photons must be energy selected, and this involves the use of soft x-ray monochromators with good resolving power. We designed a photon spectrometer to be located in the experimental chamber of one of ELETTRA's beamlines (BACH) to perform inelastic X-ray scattering measurement in the energy range 20-1200 eV with relatively high resolving power (above 2000 in most of the range). The spectrometer is based on two interchangeable mechanically ruled spherical VLS gratings with blaze profile of the grooves. The diffracted photons are collected by a back illuminated CCD of 1300X1340 pixels, each of 20X20 micrometers ² dimension. The two interchangeable gratings are inserted in or removed from the beam by manual translation and are kept fixed during the measurement. The energy scan (or selection) is made by a mono-dimensional translation of the CCD. To cover the whole energy range, including the zero order light, only a small movement (about 7 cm of linear translation) of the detector is necessary. No detector rotation or bi-dimensional displacement is needed. Since the size of the CCD is quite large, it is possible to collect, in a single shot, a very large photon energy window, about 20-30% of the full energy range of each grating. The optical layout and the expected performances are reported.
