摘要: We present the design and characterization of a compact portable spectrometer realized for photon in-photon out experiments (in particular X-Ray Emission Spectroscopy, XES), in tailored to be used at FERMI freeelectron- laser (FEL) ELETTRA (Italy). The can installed on different end stations variable distances from target area both synchrotron FEL beamlines. Different input sections accommodated in order fit experimental requests, with/without an entrance slit additional relay mirror. The design is order realize instrument within total footprint less than one square meter. The instrument based use two flat-field grazing-incidence gratings EUV-enhanced CCD detector cover the 25-800 eV spectral range, with resolution better 0.2%. absolute response spectrometer, has been measured whole region operation, allowing calibrated measurements flux. The characterization Gas Phase beamline Synchrotron as XES some experimental data emission taken EIS-TIMEX FERMI, where has been beam diagnostics, are presented.
