Retention time and cell functionality degradation under proton irradiation is studied for SDRAM references that exhibit in-flight faulty behavior on satellites. Proton irradiation, with an adapted test protocol, allows to reproduce these effects and to gain a valuable insight on this phenomenon. Data acquired allow for a physical interpretation of the degradation, which results of one or more damage...
We present radiation test data on optocouplers from three different vendors including results on neutron (1MeV) and proton (30, 60, 190MeV) induced displacement damage, total ionizing dose (Co60) and proton induced Single Event Transients.
This paper presents non destructive SEE data collected in flight on commercial SRAMs, SSRAMs and SDRAMs by MEX module. Detected events are SEU, MCU, SEFI as well as weakened cell. MEX (Module Experience) is a part of CARMEN2 instrument, launched the 22th of June 2008 aboard JASON2 satellite (1335km, 66°). This scientific instrument is dedicated to the study of space radiation effects on electronic...
The CARMEN2/MEX instrument has been measuring radiation effects on electronic devices on board the JASON2 satellite since June 22 2008. This paper presents updated data concerning destructive phenomena and complementary observations for cumulative phenomena and Single Event Transients.
The 2011 release of the OMERE freeware includes a module that allows to consider the shielding effect of the satellite geometry in the calculation of Single Event Effects (SEE) on electronic devices. This module has been applied to calculations performed for proton induced SEE aboard the JASON-2 satellite. Calculated prediction rates agree with those observed in-flight. The shielding effect has also...
