Abstract. The Laser Integration Line located at CEA-CESTA is equipped with X-ray plasma diagnostics using different kinds of X-ray components such as filters, mirrors, crystals, detectors and cameras. To guarantee LIL measurements, detectors such as X-ray cameras must be regularly calibrated close to the facility. A new X-ray facility is currently available to perform these absolute X-ray calibrations. This paper presents the X-ray tube based High Energy X-ray Source (HEXS) mainly used to calibrate X-ray cameras and also X-ray filters of plasma diagnostics. 1. THE HEX SOURCE AND THE EXPERIMENTAL SET UP The X-ray calibration STATIX laboratory located at the CEA-CESTA, near Bordeaux, provides now the HEX source, a multi-anodes X-ray tube based continuous source developed by the Optique and Électronique Appliquée company consisting of an electron gun and an anode barrel being equipped with a different material (Al, Ti, Cr, Cu, Mo, Ag) to obtain characteristic lines. The X-ray detectors calibration with HEXS is essentially performed with characteristic radiation lines provided by current-voltage set and anode material. The emission spectra are monitored by means of a CANBERRA Ultra LeGe germanium liquid-nitrogen cooled spectrometer. The Ge spectrometer acts as a photon counter and the charge collected by the Ge crystal is converted and processed b
