Compilation and systematics of proton-induced fission cross-section data

Abstract A compilation of proton-induced fission cross-section data in EXFOR has been performed. Cross-section parameterizations for target nuclei from 165 Ho to 239 Pu have been made on the basis of comparative critical analysis and selection of the data. The overall systematics that was created allows predictions to be made for nuclei for which experimental data do not exist.

Characterization of the ANITA Neutron Source for Accelerated SEE Testing at the Svedberg Laboratory

ANITA ( Atmospheric-like Neutrons from thIck TArget), a new neutron facility for accelerated testing of components and systems for single event effects, has been put into operation at The Svedberg Laboratory in Uppsala, Sweden. Results of beam characterization measurements are reported.

Heavy-Ion Induced Threshold Voltage Tails in Floating Gate Arrays

We studied heavy-ion effects on floating gate memories, focusing on the generation of tails in the threshold voltage distributions after irradiation. Using both experiments and simulations based on the Geant4 toolkit, we provide new insight, distinguishing two types of events, large events and small events, which are responsible for the secondary peak and the intermediate region in the post-rad threshold distribution, respectively. Both are well correlated with the energy deposited in the FG. Implications for error rate predictions are discussed.

Light‐Ion Production in the Interaction of 96 MeV Neutrons with Silicon

Double-differential cross sections for light-ion (p, d, t, He and α) production in oxygen, induced by 96 MeV neutrons are reported. Energy spectra are measured at eight laboratory angles from 20◦ to 160◦ in steps of 20◦. Procedures for data taking and data reduction are presented. Deduced energydifferential and production cross sections are reported. Experimental cross ∗Corresponding author, Tel. +46 18 471 6850, Fax. +46 18 471 3853, E-mail: stephan.pomp@tsl.uu.se

The New Uppsala Neutron Beam Facility

A new quasi‐monoenergetic neutron beam facility has been constructed at the The Svedberg Laboratory (TSL) in Uppsala, Sweden. Key features include an energy range of 20 to 175 MeV, high fluxes, and the possibility of large‐area fields. Besides cross‐section measurements, the new facility has been designed specifically to provide optimal conditions for testing of single‐event effects in electronics and for dosimetry development. First results of the beam characterization measurements performed in early 2004 are reported.

Fidelity of energy spectra at neutron facilities for single-event effects testing

We quantify the fidelity of neutron beam spectra for single-event effects accelerated testing. Beam spectra are folded with representative SEE cross-section curves and errors in predicted SEE rates are determined. The use of quasi-monoenergetic neutrons to complement spallation neutron sources is described. Errors can be controlled to insignificant levels even when the maximum neutron energy is below 200MeV.

COMPACT THERMAL NEUTRON SENSORS FOR MODERATOR-BASED NEUTRON SPECTROMETERS

In the framework of the NESCOFI@BTF project of the Italian Institute of Nuclear Physics, different types of active thermal neutron sensors were studied by coupling semiconductor devices with a suitable radiator. The objective was to develop a detector of small dimensions with a proper sensitivity to use at different positions in a novel moderating assembly for neutron spectrometry. This work discusses the experimental activity carried out in the framework of the ERINDA program (PAC 3/9 2012) to characterise the performance of a thermal neutron pulse detector based on (6)Li.

High-energy neutron detection and spectrometry with superheated emulsions

The response of some superheated emulsions was investigated using quasi-monoenergetic neutron beams in the 46– 134 MeV energy range at the Universit! Catholique de Louvain, Louvain la Neuve, Belgium and at The Svedberg Laboratory, Uppsala, Sweden. In order to determine the detector response to the high-energy beams, the spectra of incident neutrons were folded over functions modeled after the cross-sections for the neutron-induced production of heavy ions from the detector elements. The cross-sections for fluorine and chlorine were produced in this work by means of the Monte Carlo high-energy transport code HADRON based on the cascade-exciton model of nuclear interactions. r 2003 Published by Elsevier Science B.V.

A new neutron facility for single-event effect testing

A new facility producing intense mono-energetic neutron beams has been developed at The Svedberg Laboratory (TSL), Uppsala, Sweden. The facility utilizes the existing cyclotron and a flexible lithium target in a rebuilt beam line. The new facility can operate at unsurpassed mono-energetic neutron intensities and provides flexibility of the neutron beam properties, like energy and geometrical shape.
