CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishA compact and reliable X-ray source, based on a 5 MeV, 1 kW, S-band electron linac, has been set up at the Dipartimento di Fisica, Università di Messina. This source, coupled with a GOS scintillator screen and a CCD camera, represents an innovative transportable system for industrial radiography and X-ray tomography. Optimization of the parameters influencing the 6-7 conversion and the X-ray beam characteristics have been studied by means of the MCNP-4C2 (Monte-Carlo-N-Particle, version 4C2) code. The converter choice is the result of the study of the 6-7 conversion performances for different materials and material thicknesses. Also the converter position with respect to the linac exit window has been studied. The chosen converter consists in a W-Cu target inserted close to the linac window. In the final source project, a collimation system provides a 14 cm diameter X-ray spot at the sample position, and preliminary radiographic results have been obtained by inspecting different density materials and thicknesses.

| Abstract: | A compact and reliable X-ray source, based on a 5 MeV, 1 kW, S-band electron linac, has been set up at the Dipartimento di Fisica, Università di Messina. This source, coupled with a GOS scintillator screen and a CCD camera, represents an innovative transportable system for industrial radiography and X-ray tomography. Optimization of the parameters influencing the 6-7 conversion and the X-ray beam characteristics have been studied by means of the MCNP-4C2 (Monte-Carlo-N-Particle, version 4C2) code. The converter choice is the result of the study of the 6-7 conversion performances for different materials and material thicknesses. Also the converter position with respect to the linac exit window has been studied. The chosen converter consists in a W-Cu target inserted close to the linac window. In the final source project, a collimation system provides a 14 cm diameter X-ray spot at the sample position, and preliminary radiographic results have been obtained by inspecting different density materials and thicknesses. | |
