In-flight observations of the radiation environment and its effects on devices in the SAC-C polar orbit

This paper presents particle flux measurements and single event effect (SEE) data obtained with Influence of Space Radiation on Advanced Components (ICARE) on the SAC-C orbit (707 km, 98.2/spl deg/) for the period November 2000-June 2002. An increase of 10 MeV proton flux in the belts is clearly observed and correlated to solar proton events associated with magnetic storms. SEU rate measurements are presented for SRAM and DRAM devices, and their response to solar events shows SEU rate increases (up to a factor of 115) correlated with high-energy protons (E/spl ges/84 MeV).

Low LET cross-section measurements using high energy carbon beam [DRAMs/SRAMs]

This paper reports on results from high energy heavy ion testing of devices. The low LET zones of the cross-section curves are explored. High and low energy measurements are compared.

In Flight Measurements of Radiation Environment on Board the French Satellite JASON-2

This paper presents particle flux measurements (protons and electrons) obtained with the ICARE-NG detector on the JASON-2 orbit (1336 km alt., 66° incl.) for the period June 2008-Aug. 2010. At this altitude, the South Atlantic Anomaly is greatly broadened as compared to lower altitudes. Proton flux measurements are made in the range 27.5-290 MeV and electron flux in the range 1.6-3.6 MeV. A great care was taken to assess the influence of the satellite on the particle measurements. Comparison of measurements with the results of the AP8 MIN model are given for protons, taken into account environment anisotropy.

Memories Response to MBU and Semi-Empirical Approach for SEE Rate Calculation

This paper deals with SEE rate prediction and proposes a semi-empirical approach that makes no use of the RPP concept. The investigation is based on a reduced set of ground data and SEU/MBU results are compared with in-flight data obtained on memories on-board ICARE (SAC-C orbit). Two-dimensional mixed-mode simulations complete this study and provide first insight to understand the observed behavior

Application of laser testing in study of SEE mechanisms in 16-Mbit DRAMs

A laser experiment has been carried out on the SMJ416400 and LUNA-E 16Mbit DRAMs in order to identify the mechanism leading to severe row/column errors. The error signatures observed with heavy ions are reproduced, related to physical locations on the die and the conditions of occurrence are studied (temporal behavior...). The question of laser to ion equivalence is discussed.

In flight observation of proton induced destructive single event phenomena

MEX Experience Module is a part of CARMEN2 instrument launched in June 22 2008 aboard JASON2 satellite. This scientific instrument is dedicated to the study of the effects of space radiation environment on various electronic devices. Among all the phenomena studied in this experiment, this paper focuses on the data collected on destructive SEEs: Latch-up on commercial SRAMs and Burnout on power MOSFETs.

CARMEN/MEX test board for the study of radiation effects on electronic components aboard JASON-2 and SAC-D satellites

This article presents an experiment module to be launched in 2008 and 2010 on two separate orbits in order to provide total ionizing and displacement damage doses and single event effects measurements on selected sensitive devices.

Electron Induced SEUs: Microdosimetry in Nanometric Volumes

The sensitivity of nanometric technologies, to electron induced single-event upset (SEU), is analyzed thanks to some microdosimetry calculations performed into nanoscale volumes, using the GEANT4 MicroElec low-energy electron transport module. The electronic showers are shown to be able to deposit ionizing energy comparable to SEU threshold energy. However, down to 16-nm technologies, it is difficult to trigger some SEUs with incident electrons without reducing the applied bias voltages. For high-energy electrons ( ), some other physical process can produce single-event upsets. The potential role of electron/coulombic interaction is investigated.

Radiation environment measurements with SPICA on-board the MIR station

Spectre de Particules et Influence sur les Composants Avances (SPICA) is an integrated test bench for the study of the space environment and its effects on electronic devices. Particles detection results measured in MIR orbit are presented and compared to the prediction of the AP8 model (proton flux and South Atlantic anomaly position). A two-dimensional correlation technique is used to estimate the shielding of the MIR station.

A Statistical Method to Extract MBU Without Scrambling Information

This paper reports on a new method for extracting MBUs from standard SEE data without the need for the physical organisation of the memories. Efficiency of the method proposed here is quantified through a reduced set of parameters.
