AbstractA description is given of the X‐ray facility installed at LAX (Laboratorio per Sperimentazioni con Radiazioni X), jointly operated in Palermo by the DEAF (Department of Energy and Physics Applications) of the University of Palermo and the IFCAT (Institute of Cosmic Physics and Informatics) of the Italian National Research Council. The X‐rays are produced by bombarding a target with energized electrons up to 60 keV.Depending on the material of the target, characteristic fluorescence lines as well as continuous bremsstrahlung is emitted.The X‐ray beam has an operational energy range of 0,1–25 keV with a flux of 1010–1012photons/sr · s; the beam, collimated on a length of 10,5 m, has a diameter at full aperture of 200 mm with a divergence of 1°.The beam line consists of:the X‐ray generatorthe Beam Channelthe Sample Chamber with a table capable of translation along the X, Y and Z axes and rotation around Y and Zthe Detector Chamber with translation movements along the X and Y axes and rotation around Y.The X‐ray generator chamber operates at 10−9hPa, whereas the other parts operate at 10−6hPa.The beam line has been developed by RIAL Vacuum S.p.A. following the specification
