The "Livio Scarsi" X-Ray Facility at University of Palermo for Device Testing
2015
In this work, we report on the characteristics of the Livio Scarsi X-ray facility at University of Palermo. The facility is able to produce low energy X rays, within the energy range of 0.1-60 keV, with fluence rates ranging from 105-108 photons/mm2 s. The laboratory is equipped with an innovative digital detection system, based on semiconductor detectors (Si and CdTe detectors), able to provide accurate and precise estimation of the fluence rate, the energy and the exposure of X rays, even at high counting rate conditions. Instrumentation for electrical characterization (DC-AC) of semiconductor devices, for both off-line and on-line (i.e. during the irradiation) measurements, is also avail…
Le facilities di irraggiamento del DEIM per il testing di componenti rad-hard
2015
Il Dipartimento Energia, Ingegneria dell’Informazione e Modelli Matematici dell’Università degli Studi di Palermo (DEIM), ospita due facility di irraggiamento impiegate per attività di didattica, sperimentale e di ricerca: • Impianto di irraggiamento Gamma Sicilia 3 (IGS-3); Irradiatore neutronico Am-Be. In questa monografia sono presentate le caratteristiche dei due impianti di irraggiamento insieme alle proprietà di interazione delle radiazioni con la materia, con particolare riferimento agli effetti sui componenti elettronici.
EVALUATION OF GAMMA-RAY AND NEUTRON FLUXES IN A NEUTRON IRRADIATOR USED FOR RAD-HARD ELECTRONIC COMPONENTS TESTING
2015
An irradiator with four Am-Be neutron sources (activity 111 GBq each) was used for testing electronic RAD-HARD components developed for space application [1]. For this goal, an essential requirement to be met is the knowledge with sufficient precision of neutron and gamma-ray fluxes in the irradiation channel where the components are put for the test. For this goal, an experimental measurement activity was started to validate also Monte Carlo simulation results, obtained with application of MCNP5 code. As regards gamma-ray flux, we considered separately two gamma-ray contributions: the first one, at 60 keV energy, associated with the decay of the 241Am, and the second one, at 2.2 MeV, due t…
