We describe a proposed neutron irradiation facility for studying neutron-induced Single Event Effects (SEE) in microelectronic components and systems at the new variable energy high current proton cyclotron (35-70 MeV; 750μA) soon to be operational at LNL. We describe the progress in designing two neutron production targets to furnish continuous atmospheric-like neutron differential spectra: a W-based thick target (to stop 70 MeV protons), and an innovative composite target made of Beryllium and Tantalum or Lead. We also describe the layout of the facility that will also house quasi-monoenergetic neutron (QMN) and direct proton beam lines. The thick target beam line could be available as soon as the new cyclotron is commissioned. The composite target and QMN beam lines, to be designed in concert, would be completed soon after.

Abstract
We describe a proposed neutron irradiation facility for studying neutron-induced Single Event Effects (SEE) in microelectronic components and systems at the new variable energy high current proton cyclotron (35-70 MeV; 750μA) soon to be operational at LNL. We describe the progress in designing two neutron production targets to furnish continuous atmospheric-like neutron differential spectra: a W-based thick target (to stop 70 MeV protons), and an innovative composite target made of Beryllium and Tantalum or Lead. We also describe the layout of the facility that will also house quasi-monoenergetic neutron (QMN) and direct proton beam lines. The thick target beam line could be available as soon as the new cyclotron is commissioned. The composite target and QMN beam lines, to be designed in concert, would be completed soon after.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
