The X-ray Facility at LAX in Palermo

1996

A 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 1010–1012 photons/sr · s; the beam, collimated on a length of 10,5 m, has a diam…

Air fluorescence efficiency measurements for AIRWATCH based mission: Experimental set-up

1998

In the framework of the AIRWATCH project we present an experimental set-up to measure the efficiency of the UV fluorescence production of the air using hard X-ray stimulus. The measures will be carried out at different pressure and temperature to emulate the same condition of the upper layers of the atmosphere where X-ray and gamma ray photons of Gamma Ray Bursts are absorbed.
