The SPES project, based on a variable energy high current proton cyclotron (35-70 MeV; 750 μA), soon to be operational at LNL, foresees a neutron irradiation facility for Single Event Effects (SEE) studies on microelectronic components and systems. The proposed facility will comprise both a beam line with continuous energy atmospheric-like neutron production targets, and a Quasi Mono-energetic Neutron (QMN) beam line. A direct proton beam line is also foreseen. Here we describe the general features of the proposed QMN beam line. The quasi mono-energetic neutrons will be produced in various thin Be and Li targets and the spent proton beam will be magnetically deflected towards a beam dump. The layout of the facility with a multi-angle collimator scheme for tail corrections is presented and the proton currents necessary to deliver high neutron fluxes using thin Be targets are estimated.

Abstract
The SPES project, based on a variable energy high current proton cyclotron (35-70 MeV; 750 μA), soon to be operational at LNL, foresees a neutron irradiation facility for Single Event Effects (SEE) studies on microelectronic components and systems. The proposed facility will comprise both a beam line with continuous energy atmospheric-like neutron production targets, and a Quasi Mono-energetic Neutron (QMN) beam line. A direct proton beam line is also foreseen. Here we describe the general features of the proposed QMN beam line. The quasi mono-energetic neutrons will be produced in various thin Be and Li targets and the spent proton beam will be magnetically deflected towards a beam dump. The layout of the facility with a multi-angle collimator scheme for tail corrections is presented and the proton currents necessary to deliver high neutron fluxes using thin Be targets are estimated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
