After the commissioning phase, it received the first external users at the end of 2012. The design and characterization of the LDM photon transport system is described, detailing the optical components of the beamline.en540 Chemie und zugeordnete Wissenschaften550 Geowissenschaftenbeamlinefree-electron laserlow-density matterphoton transportmetrologyThe Low Density Matter (LDM) beamline at FERMI: optical layout and first commissioningArticle1600-577525931066
