Reducing soft error rate of socs analog-to-digital interfaces with design diversity redundancy
(Institute of Electrical and Electronics Engineers [Society Publisher], 2019-11-11)
Neste artigo, um system-on-chip programável comercial (PSoC 5, da Cypress Semiconductor) é testado sob irradiação de íons pesados com foco nos blocos de interface analógico-digital do sistema. Para tanto, um sistema de ...
Evaluating Soft-Core RISC-V processor in SRAM-based FPGA under radiation effects
(2020)
Abstract— This article evaluates the RISC-V Rocket processor
embedded in a Commercial Off-The-Shelf (COTS) SRAM-based
field-programmable gate array (FPGA) under heavy-ionsinduced faults and emulation fault injection. We ...
Combined ionizing radiation & electromagnetic interference test procedure to achieve reliable integrated circuits
(2019-07-26)
International standards have been proposed and used to test Integrated Circuits (ICs) for Total-Ionizing Dose (TID) and Single-Event Upset (SEU) as well as for Electromagnetic Interference (EMI). Nevertheless, these standards ...
The study of natural radiation distribution in soil of São Bernardo do Campo.
(2008-10-05)
We have studied the distribution of natural radioactivity in the soil of five sites of the city São Bernardo do Campo, São Paulo, Brazil. The main contribution of the radiation dose is due to the isotope 40K, with smaller ...
Thermal neutron induced upsets in 28nm SRAM
(2019-01-01)
In this work, we present the first results of static tests in a 28nm SRAM under thermal neutron irradiation from the IPEN/IEA-R1 research reactor. The SRAM used was the configuration memory of a Xilinx Zynq-7000 FPGA and ...
First comparison of GEANT4 hadrontherapy physics model with experimental data for a NUMEN project reaction case
(2020-05-26)
Gamma-ray and neutron spectra from the 18O +76Se reaction at 15.3 MeV/u were measured with the EDEN array of liquid scintillators at the LNS. The results were compared to GEANT Hadrontherapy physics list simulations in ...
A proposal to study long-lived isotopes produced by thermal neutron irradiation of digital devices
(2019)
In this work, we present a facility to study errors in digital devices exposed to thermal neutrons from a beam hole in the IEA-R1 nuclear reactor, as well as the long-lived isotopes produced in the irradiation of digital ...
Single-event effects: experimental setup for power MOSFETs and diffusion model for cross section calculations in low-voltage MOSFETs
(2019-01-05)
MOSFETs are subject to di erent types of Single-Event E ects (SEEs) induced by heavy ions, with low-voltage MOSFETs being more susceptible to non-destructive e ects, such as Single-Event Transients, than high-voltage MOSFETs ...
Recent results on heavy-ion direct reactions of interest for 0νββ decay at INFN - LNS
(2020-01-05)
Neutrinoless double beta decay of nuclei, if observed, would have important implications on fundamental physics. In particular it would give access to the effective neutrino mass. In order to extract such information from ...
